Guide to Using Harris Parts List Information
The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index.
The example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill
of materials table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output
Cabinet. In the Replaceable Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one
indentation level below the Transmitter and implies that they are used in the Transmitter. The Controller Board is
indented one level below the Control Cabinet so it will show up in the bill of material for the Control Cabinet.
The tree structure of this same index is shown to the right of the table and shows indentation level versus tree
structure level.

The part number of the item is shown to the right of the description as is the page in the manual where the bill for
that part number starts. Each table headings is in the format of; Table #-#. ITEM NAME - HARRIS PART
NUMBER - this line gives the information that corresponds to the Replaceable Parts List Index entry (NOTE:
The letter in parenthesis, following the part number, represents the current—at time of this printing—revision);
Inside the actual tables, four main headings are used:
•
•
•
•
HARRIS P/N column gives the Harris part number (usually in ascending order);
DESCRIPTION column gives a 25 character or less description of the part number;
Qty UM column notes the quantity and unit of measure of the item;
REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e.,
C001, R102, etc.) that corresponds to the number found in the schematics (C001 in a bill of material is
equivalent to C1 on the schematic) or 2) gives added information or further explanation (i.e., “Used for
208V operation only,” or “Used for HT 10LS only,” etc.).
NOTE: Inside the individual tables some standard conventions are used:
•
•
•
A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column means that this item is used on or with C001 and is not the actual part number for C001.
In the ten digit part numbers, if the last three numbers are 000, the item is a part that Harris has purchased and has not manufactured or modified. If the last three numbers are other than 000, the item is
either manufactured by Harris or is purchased from a vendor and modified for use in the Harris product.
The first three digits of the ten DIGIT part number tell which family the part number belongs to - for
example, all electrolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic
(can) capacitor is found to have a 9xx xxxx xxx part number (a number outside of the normal family of
numbers), it has probably been modified in some manner at the Harris factory and will therefore show
up farther down into the individual parts list (because each table is normally sorted in ascending order).
Most Harris made or modified assemblies will have 9xx xxxx xxx numbers associated with them.
The term “SEE HIGHER LEVEL BILL” in the description column implies that the reference designated part
number will show up in a bill that is higher in the tree structure. This is often the case for components that may
be frequency determinant or voltage determinant and are called out in a higher level bill structure that is more
customer dependent than the bill at a lower level.

Introduction
The FlexStar HDx is a new dual-output, tri-mode HD Radio™ capable exciter. With the optional Exgine Module,
the two configurable RF outputs are available for three different modes of operation: FM, FM+HD, and HD only.
The Main output is capable of up to 55 watts and the AUX output is capable of up to 10mW, depending on mode.
The three modes available with the Exgine Module option installed are:
•
•
•
•
HD: Generates the digital sidebands for use in "digital-only" transmitters.
FM+HD or hybrid mode: For use by common amplification FM transmitters. The HD to FM ratio is easily set
using the touch-screen GUI.
FM: Analog FM only mode capable of up to 55 watts.
There is also a specialized purchased option for driving two combined transmitters called Split Level Combining (SLC) mode. Typically a larger FM-only transmitter and a smaller FM+HD transmitter.
Other products in the FlexStar family include the HDI Importer and the HDE Exporter. These products create an
HD Radio system for a new level of digital radio capabilities.
An HDx-FM analog exciter can be upgraded to HD by adding the iBiquity DSP-based modulator called Exgine
(available with or without Host Audio Extraction [HAX]). To transmit HD Radio carriers, an HDE Exporter will
have to be added to your system. A Harris HDI Importer can also be added to allow Supplemental Program
Services (SPS) for multicasting, or other data services known as Advanced Application Services (AAS).

SPS - Supplemental Program Service. Also referred to as Supplemental Audio Service, Supplemental program
audio is input to the HDI Importer in AES3 digital format.
MPS - Main Program Service. The stations main program audio delivered from the station’s on-air studio. At
the time of this printing, the MPS program must be identical to, and time-aligned with, the analog FM signal.
MPS PAD - Main Program Service Program Associated Data, now utilized as Program Service Data (PSD).
Program related data such as song title and artist information. Delivered in the iBiquity protocol from the station’s audio hard disk storage system via an Ethernet communications port. This data is fed to the HDE
Exporter to be transmitted and ultimately displayed as text on an HD receiver.
SPS PAD - Supplemental Program Service Program Associated Data, now utilized as Program Service Data
(PSD). Identical to MPS PAD but for SPS audio service.
AAS - Advanced Applications Service. Non-program related data services encoded into the HD bitstream and
includes Supplemental Audio, traffic information, news, weather, stock quotes, etc. The first AAS to be implemented in HD receivers will be Supplemental Audio channels. The HDI ingests, manages and multiplexes all
AAS services for HD Radio.
EOC - Ensemble Operations Center for the HDI Importer. The functional capabilities to manage the transmission, configuration and status of all AAS inputs.
ECC - Exporter Control Center for the HDE-200. It has two main functions: To configure or define the operational parameters for one or more HDE-200 Exporters; and to allow multiple computers to be able to remotely
monitor HDE-200 operations.
AES3 - Abbreviation for AES3-1992 which is the established standard for professional digital audio conveying
two channels of periodically sampled and uniformly quantized digital audio on a single twisted pair wire. The
sample rate standard for HD Radio is 44.1 kHz.
Common Amplification - Also referred to as Low Level Combining. Common amplification utilizes a single
transmitter and it’s associated IPA and PA stages to amplify a hybrid HD+FM signal that has already been
combined with the proper power ratios at the exciter stage.
Separate Amplification - Uses the station’s existing FM transmitter and an HD transmitter that amplifies the
digital signal only. These 2 are combined in a high-power 10dB combiner.

Split Level Combining - A Harris exclusive method of developing a hybrid FM signal using a combination of
separate amplification and common amplification providing minimum reject power and overall dissipation and
maximum combining efficiency and overall AC to RF efficiency of greater than 50%.
Separate Antennas - The technique that employs an existing FM antenna and a second antenna for transmitting
the HD Radio digital sidebands. The analog and digital signals are effectively combined in space. The primary
advantage of using separate antennas is very low loss to the HD signal, significantly reducing the HD transmitter power requirements. The primary disadvantage is unequal azimuth radiation patterns and resulting variation of the analog to digital signal ratios.
Dual Input Antennas - a low loss method of developing an FM+HD hybrid signal. Dual input antennas utilize
two RF inputs, one for FM and a second for the HD transmitter. They combine the HD and FM signals and
each element radiates a hybrid FM+HD signal.
Interleaved Antennas - a low loss method that employs two antenna inputs; one for FM and a second for the
HD signal. In an interleaved antenna system the antenna bays are alternately radiating the FM and HD signals.
The following paragraphs provide a brief description of the various EOC components.

EOC Database: The persistent data for the functioning of the EOC is stored in the EOC database. All the
Administrative functionality is handled by interaction with this database. Administration is basically an offline
activity to enable broadcast stations to configure the EOC according to their requirements. Other EOC components like the Connection Manager and the Logistics Processor write data about their functioning into the EOC
Database. The EOC Monitor component connects to the EOC database to view the status of the EOC and the
data.
SPS Processor: The SPS Processor captures the multiple audio streams and performs the HDC (HDRadio
Codec) encoding. It also captures the SPS Program Associated Data (PAD) data packets and performs the
encapsulation of these data packets. The SPS Processor is also responsible for the multiplexing of the encapsulated SPS PAD within the encoded audio streams.
Logistics Processor: The Logistics Processor is responsible for the data reception from the service providers in
accordance with the specific protocol chosen for that particular service provider. It is also responsible for managing the bandwidth and Quality of Service (QoS) for each service provider as defined in the Contracts
between the service provider and the broadcast station. It communicates with the Connection Manager as well
as the Exporter. It also communicates with the EOC Database in order to retrieve configuration information
and save its performance data.
Connection Manager: The Connection Manager is responsible for managing the connections from the various
service providers. It authenticates service providers and delivers the specific information regarding the Contracts and Services for each service provider. It provides the mechanism for service providers to deliver data
services to the EOC. It allows multiple service providers to connect to the EOC as well as for multiple services
to be delivered from either one or multiple service providers. The Connection Manager connects to the EOC
Database for authentication information as well as to the Logistics Processor for bandwidth and QoS information.
Contract Management API: Service providers deliver data services to the EOC based upon their ‘Contracts’
with the broadcast stations or the EOC with regards to the services sent and the bandwidth and QoS requirements. The Contract Management API provides a standard interface for client applications to add data about
service provider contracts to the EOC Database and to administer this information.
Exporter Configuration API: The Exporter Configuration API basically supports the ability to configure an
exporter in order to support data services. It provides a standard way for client applications to access and configure an exciter through an exporter. The API supports the management of station information, mode configuration and channel configuration, which enables clients to allocate bandwidth resources for data services.
Monitoring API: The Monitoring API allows real-time monitoring of the EOC. It provides a standard way for
client applications to monitor EOC activity and configuration details about the EOC. It provides an interface
for viewing EOC configuration, service provider connections, services sent, throughput and application functionality.

Service Provider API: The Service Provider API provides a common interface for service providers to access
and deliver data services to the EOC. It helps in the connection/disconnection of services to the EOC. It provides the communication protocol used between applications and the EOC Connection Manager. It allows for
service provider authentication and error reporting. The Service Provider API supports discrete object broadcast which allows a service provider to send variable-sized objects of arbitrary data types over the HD Radio
system.
HD PAD API: The HD PAD API allows applications to create and transmit PAD content. It allows for application to input PAD data without having to worry about the data encoding and transfer protocols. The PAD API
transfers the data streams to the SPS Processor in the EOC where it is multiplexed with the audio streams.
Resource Manager/EOC Monitor: The Resource Manager and the EOC Monitor are sample client applications
which are used to configure and monitor the EOC through the various APIs. The Resource Manager provides a
graphical user-interface which combines the functionality of Contract Management and the EOC Administration through the Contract Management API and the Exporter Configuration API. The EOC Monitor helps in
monitoring EOC functionality through the Monitor API. The EOC components are designed so that various
such that other such third-party applications can be developed to access the full EOC functionality through the
APIs.

Quick Start
BENCH TEST FOR HDx EXCITER TO EXPORTER ETHERNET COMMUNICATION.
1. Before operating the FlexStar HDx-FM Exciter, unlock the PLL shipping screw on the rear of the exciter.
2. If you are going to connect an Exciter to a DEXSTAR that will be converted to an Exporter, a new product key
for the DEXSTAR must be obtained from the factory prior to operation. Contact Customer Service for a new
product key.
3. If externally mounting the Exciter, use shelf part number 992-9854-011 to house the exciter. Do not use a shelf
intended for a Digit exciter, they appear similar but does not have sufficient ventilation for the HDx-FM.
4. Use the supplied memory stick to save user configurations after final installation. Multiple configurations can
be saved on the same memory stick. See section 5 of this manual.
5. Test the Exciter and Exporter back to back to verify communication prior to configuration for your network.
This step will save much time when troubleshooting non-communication issues.
Before installing, with equipment located at separated sites, it is required to bench test the Exciter and Exporter
together as a system to validate that these units do communicate properly over Ethernet with each other, before
separating them via a Network or STL link. This will provide you a valid point of reference if any communication
issues arise during installation into your system.
Until the units are configured properly there will be communication problems. The Harris factory configures
“Default” IP addresses in these components before shipping them, that will allow quick and easy testing. After
completing bench testing, other IP addresses assigned by your network administrator may be used to operate with
local equipment.
If your unit(s) have already had their IP addresses changed then setting them back to these basic addresses will help
with troubleshooting. However the units need to be operated separately from a local LAN while using these
addresses.

over an STL from the Exporter to the FlexStar exciter; obtain the Exporter Link MAC address,
from Serial Setup 4/4 in the exciter, and enter that it in the Exporter network configuration page.
Make sure you use the correct MAC as the exciter has four of them. You may reduce the complexity of the installation by clearing this Exciter MAC field in the Exporter when a bidirectional
Ethernet STL is used.
NOTE:
Exciter Link Note: For the Exporter to serve multiple Exciters you may use a broadcast address.
i.e. 10.10.10.255. However please note that broadcast packets will not pass through a router to
another network
2.2.1
Bench Testing:
Before proceeding it is recommended to save the exciter’s configuration on a USB memory stick. Leave Config 1
for the fresh from the factory Config and use Config 2 or higher. Make sure that the USB memory device has the
lock switch off if equipped with one. See: Sections 3 and 6 of the HDx-FM manual.
1. Connect the FlexStar exciter’s Exporter Link Ethernet port to the Exporter’s Ethernet port using a crossover cable. Straight through cables may be used when an Ethernet Switch is located between the units. CAUTION: During this test do not connect these units to a network with other traffic.
2. Terminate the Exciter into a 50 ohm load capable of dissipating the set power output of the exciter. Maximum
exciter power is 55 watts in FM mode. (NOTE: if a test load is not available, customer may optionally leave
exciter terminated in its host transmitter).
3. Connect a monitor, keyboard, and mouse to the Exporter.
4. Power up the Exporter and exciter.
5. Verify the IP addresses listed above.
6. An exciter RF output test is only possible if its RF mute line is held in the proper logic state, or if the mute line
is temporarily disabled. To disable the mute line for RF test, see the Installation section, TX remote connector.
If the exciter is not making power and you want it to:
- Go to Output Setup 1/4 (Setup, Output) and select Transmitter Type: Stand Alone.
- Go to Advanced Setup Page 3/4 (Setup, More Setup, Next, Next) and adjust mute settings as needed to un-mute
the exciter. Make sure Mute button at bottom center of screen is not selected to Mute.
7. To verify communication to the exciter; navigate to the EXGINE screen in the exciter’s Signal Processor Status 3/5 screen. The fields HD Buf, DSP Run and EL Run should be OK (not FAULT).
The next step is to install the units into your network and possibly change the IP addressing to match your network
addressing. (If you are unfamiliar with IP addressing, check with your network administrator).

FlexStar™ HDx-FM
Troubleshooting
If the exciter stills shows a warning and HD Buf fault:
a. Cycle the exciter’s AC power to imbed the new IP address, wait 20 seconds before reconnecting the power.
b. Make sure that the IP configuration in the Exporter has been saved (requires a reboot).
c. Make sure the Ethernet cable is plugged into the Exporter Link port on the exciter.
d. The exciter’s Exporter Link Ethernet port should have one steady LED and a flashing LED.
e. Carefully check all IP address setups in your system.
f. Firewalls and routers may need additional re-configuration.
g. Ethernet STLs have limited bandwidth that is being exceeded by other network traffic.
h. Some Ethernet switches cause poor HD radio performance, temporarily bypass or replace the switch.
i. If the simple setup with only a crossover cable was not tried then go back and try that.
j. Connect a PC, addressed as above except use 10.10.10.30 for the IP address with a crossover cable to each
unit, one at a time. Then use the PING command, in a DOS window, to verify that each unit’s port works.
2.2.2.1
MPS PAD
The interconnection for MPS PAD (now called MPSD) begins at the automation system equipment at the
studio (Audio Vault, Prophet etc.). Typically it is over Ethernet and needs to connect to the Exporter.
MPS PAD (MPSD) can also be connected to the Exporter over an RS232 serial connection to the DB9 on
the rear panel.
2.2.2.2
Required Ethernet Switch
A HUB or Switch is required to be used when the system has any additions to the basic Exporter and FlexStar
exciter. Without a switch, adding an Importer and an Ethernet MPS PAD data source connection will exceed the
Exporter’s number of connections. In addition, an SPS PAD (now called SPSD) source also needs to use Ethernet,
to reach the Importer, which requires yet another port.
2.3
Unpacking
Carefully unpack the Exporter and preform a visual inspection to determine if any apparent damage was
incurred during shipment. Retain the shipping materials until it has been verified that all equipment has
been received undamaged. Locate and retain all PACKING CHECK LISTs. Use the PACKING CHECK
LIST to help locate and identify any components or assemblies which are removed for shipping and must
be reinstalled. Also remove any shipping supports, straps, and packing materials prior to initial turn on.
2.4
Returns and Exchanges
No equipment can be returned unless written approval and a Return Authorization is received from
HARRIS Broadcast Communications Division. Special shipping instructions and coding will be provided
to assure proper handling. Complete details regarding circumstances and reasons for return are to be
included in the request for return. Custom equipment or special order equipment is not returnable. In
those instances where return or exchange of equipment is at the request of the customer, or convenience
of the customer, a restocking fee will be charged. All returns will be sent freight prepaid and properly

connect between the balanced composite input and the composite sources, balanced or unbalanced outputs, per you
choice. The center conductor of the triaxial cable and inner most shield should be terminated in a standard BNC
male cable connector. This connector will mate with the Balanced composite input. The outermost shield should be
lugged and connected to the ground stud on the rear of the exciter. The source end of this cable should be
terminated in a similar manner using a connector compatible with the source equipment. This will provide the most
effective barrier against unwanted noise or hum effecting the composite audio signal.
Triaxial cable of specific lengths already terminated with a BNC connector and ground lug on each end are
available by contacting the Harris Factory. Select the shortest length possible as unnecessarily long cable lengths
can result in undesirable amounts of roll-off of the composite amplitude response; this is due to the progressive
increase in cable shunt capacitance as cable length increases.

NOTE - The triaxial cable used to make this composite input connection is of the type with two individual shields
that are insulated from one another. Double shielded cables without an insulating material between the two shields
will not work properly in this application.
The SCA inputs are analog, 1 - 4vp-p for 7.5 kHz deviation. The input gain is controlled from the front panel
electronically for a +/-6dB range. They connect to a BNC female connector, unbalanced, 10K ohm input
impedance. The configurable Aux Composite/SCA input must adhere to the same input levels as the other inputs; 1
- 4vp-p for composite and 0.9 - 1.5vp-p for SCA.
2.6.4.6.2 RF Sample Inputs
Four RF samples are also applied to the BNC I/O board. Two are internal to the Exciter; from the D/A filter board
output and from the Exciter PA output and need no customer connection. The other two are external from the
Exciter for RTAC (real time adaptive correction) and will come from the output of the transmitter and combiner,
connected to the SMA connectors labeled XMTR and FILTER. These inputs are for the precorrector circuit and are
to be +5 dBm maximum at full output power. Achieve this level by adjusting the coupling value of the sample pickup or use in-line attenuator pads.

Exporter Interface (Exgine Module)
These connections are to connect to the Harris FlexStar Exporter. There are two Ethernet ports; Exporter link and
Ethernet3 which connect to the Exgine board in Exciters utilizing HD generation.
2.6.4.7.1 Exporter Link
When connecting the Exporter to the Exciter, use the appropriately labeled Ethernet port on the rear panel; Exporter
Link. A direct connection can be made, however if the Exporter and Exciter are not located in the same area, a
different kind of link is needed; STL or IP for example.
One method would be through a switch located at the Exporter and at the Exciter end of an Internet link. After a
connection to the Exciter is made, turn on the Exciter, if DHCP IP addressing is desired and previously selected,
one was generated when the unit was turned on and the connection was present. On the GUI screen of the Exciter,
locate the DHCP IP address and then enter that address into the Exporter screen for this link.

For Static IP addressing, consult your network administrator for available addresses.
An STL can also be used, such as the Intraplex STL. The output of the Exporter is 100BaseT that goes into the
STL. The output of the STL at the transmitter side is also 100BaseT.
A firewall is recommended for telnet or FTP on the ethernet input labeled Exporter Link. UDP will use port 8145,
ensure this port has been opened on the firewall if the UDP can not connect.
NOTE:
HDE-200 Exporter has Port # control which may interfere with PSD (used to notated as PAD)
traffic when using UDP. If you feel this is the case, using the ECC control software simply toggle
to TCP, then back again to UDP. This should reset the port # to be correct for PSD traffic.

Signal Processing
The Signal Processing board serves as the main board in the Exciter. Thus, the communications with the Exciter
connect to the Signal Processing board and are listed here.
2.6.4.9.1 Communication Ports (COM1, COM2, Plat-Z Serial)
There are two COM ports and a Platinum-Z FM interface port on the rear panel. All are 9 pin female sub D
connectors for RS232, pin out is below.

The COM1 and COM2 ports are used for VT-100 and factory programming. They are standard RS-232, but do not
support handshaking.
The Platinum-Z serial will connect to the Display Backplane board in the Platinum Z HD+ transmitter control
cabinet. The connector labeled Plat-Z Serial connects to J24 on the transmitter display backplane board using a
cross-over cable. If two Exciters are used, the second one connects to J25 on the transmitter display backplane
board. Wires 2 and 3 that interconnect will have to be crossed, i.e. the transmit pin (TxD) on one end connects to
the receive pin (RxD) on the other end.
2.6.4.9.2 CAN Bus Connection
For systems utilizing one or more HDx-FM exciters along with one or more BoostPro amplifiers, the
CAN buss provides the control signal path across a shielded twisted pair cable between DB-9 connectors
labeled CAN on both the HDx-FM and the BoostPro rear panels.
Special terminating adaptors are provided to allow custom routing of all CAN cables between DB-9
connectors. These adaptors allow you to route the CAN circuit any way you like. The only limitation is
that only two cables can be attached to any one connector/adaptor (cable length should not be an issue as
maximum cable length for a CAN connection is 200 feet).

Secure the cable to the adaptor using the screw terminals as follows:
• CANL: Clear-jacketed conductor(s) to terminal 1
• CANH: Blue-jacketed conductor(s) to terminal 2
• Shield wire(s) to terminal 3
If two CAN cables will be connected to a single adaptor, twist and lightly solder the like conductors together before
attaching to adaptor.
Example: Twist and solder the blue-jacketed CANH conductor of one CAN cable, to the corresponding bluejacketed CANH conductor of the 2nd CAN cable, before securing to Terminal 2 of the CAN Adaptor. For this type
of 2-cable connection, the adaptor will not need terminating (see STEP 4 below).
STEP 4
Set Jumper J3 as follows:
• When a single CAN cable is connected to a device, the adaptor will require a termination at that end - Set J3 across IN pins
When two CAN cables connect to a single device, the adaptor will NOT require a termination for that connection Set J3 across OUT pins (however, the opposite end of either of these cables will most likely connect singly to
another device, requiring termination).

2.6.4.9.1 19kHz Out
The FM 19kHz stereo pilot signal is generated in the Modulator DSP as part of the FM modulation. The DSP
provides pilot samples to the FPGA to allow synchronization of external RDS/RBDS equipment to the pilot signal.
The FPGA uses the sample data to drive the Sampling Stereo Audio D/A Converter. The 19kHz pilot signal from
the audio D/A converter is then buffered and goes to a BNC connector on the rear panel of the exciter. Output level
is 4.5V p-p.
2.6.4.9.2 1PPS In
Pilot sync is used in single frequency FM networks (SFN) and requires a 1PPS input to synchronize all transmitters
in the network. Since the 19kHz pilot is internally generated by the Modulator DSP, the 1PPS interrupt is supplied
to the DSP for this purpose. The DSP synchronizes the pilot to 0o phase when the interrupt occurs. This 1PPS will
generally come from a GPS receiver or some other source. The input is TTL level, 50 ohms.
2.6.4.9.3 Ethernet Connection
The rear panel Ethernet 1 and Ethernet 2 connections are a 10/100 baseT Ethernet connection. These can be
connected through a standard network switch or hub for remote management and software updates of the Signal
Processing board. Telnet to the IP address of the Exciter for a VT100 display of limited status and control

Introduction
The Exciter will need to be configured to your specific system application.
NOTE:
The user settings are stored on a USB jump drive when it ships from the factory. This Config file
(normally Config #1) contains YOUR user settings. After you have achieved optimum settings/
configuration save them again on the USB drive (typically saved to Config #2, or above, so you
can always go back to the factory settings of Config #1). The RESTORE DEFAULTS button will
NOT restore your user settings. All user settings in the Exciter will be lost with RESTORE
DEFAULTS! Restore Defaults sets the Exciter back to a factory pre-test condition. After performing a RESTORE DEFAULTS, you will need to load your user setting back into the Exciter from
the USB jump drive.
See "6.11 Restore Defaults" on page 6-7 for more information.
IMPORTANT:
It is recommended that you copy these config files ("HDXFM02.CFG") to a PC or some other
offsite storage device. Do not rename these files.
Use a separate, dedicated USB jump drive for every unit. DO NOT use a USB jump drive that has been formatted
to Linux (like that used in a DEXSTAR Exciter). Inserting a flashdrive formatted in Linux may cause the FlexStar
HDx-FM Exciter to malfunction. Also do not use a USB jump drive from another HDx-FM Exciter as it will
overwrite the files. The FlexStar HDx-FM supports USB 2.0 low speed only.
NOTE:
After making any parameter changes on any of the Setup configuration screens, the HDx exciter
must be "rebooted" by power cycling the unit: Unplug the AC cable from the source, then after
waiting 10 - 15 seconds plug the unit back in.
3.2
Operation Through the Front Panel
Operation of the Exciter is through color touch screens: Setup and Status. The Status screens can be accessed at
anytime by using the physical buttons on the right side of the Exciter front panel. The LEDs to the right side of the
touchscreen indicate the condition of the Exciter; red = fault in that functional area of the Exciter, green = okay.
Pressing the button next to the red LED, or selecting the same on-screen button from the Status Home page will
take you to the Status page that will indicate the fault.

NOTE:
Window parameters will be grayed out when they are not available for adjustment. Example;
when the Composite input is disabled, the adjustments associated with it are grayed out since they
are irrelevant. When Enabled, these windows will not be grayed out and will allow user interaction.
The Input Setup screens select the input audio sources and you select the priority of the sources; primary and
backup. These inputs are physically at the XLR and BNC boards on the rear of the Exciter. Select between: Main
AES, Aux AES or the main Composite as the primary inputs. This switching can be automatic or manual. Select
the length of time the exciter waits until it switches and the threshold that the input must fall to before it switches
(in automatic switch mode). It is a one-way switch - Primary to Backup - it will NOT switch back to the Primary if
that signal resumes. That requires operator intervention.

This will preset parameters in the Exciter to optimum values for that particular Harris transmitter type. After those
have been loaded, you may modify the settings from that starting point and save them as a "Custom" setting. It’s
advisable to save these to a USB jump drive (DO NOT use a jump drive previously formatted for Linux operating
system - See "3.1 Introduction" on page 3-1). If your transmitter is not listed, select the transmitter most similar to
your transmitter and customize it from there.
With the release of version 2.43 of the Flexstar Exgine, support for TCP/IP communications became available.
Detection of either UDP or TCP is done automatically within the Exgine (Note status in upper right hand of Figure
3-14 on page 3-16). Support for TCP connections required additional buffering of the E2X data stream coming
from the Exporter. A maximum of 2786 ms of buffering is available to assure robust connection across jittery
networks. This additional buffering may now place the total required diversity delay beyond the capabilities for
some 3rd party external delay units. A configuration control has been added on page 1/5 of the Output Setup screen
to allow reduced buffering to accommodate diversity delay units of less than 10 seconds duration.
In TCP mode, the default buffer depth is 15 blocks or (15 x 0.093 sec.) which is equal to 1.486 seconds. In UDP
mode, the default buffer depth is 2 blocks or 186ms. Adjustment of the buffer depth is accomplished by using the

There are several methods of combining the analog (FM) and digital (HD) RF to create an IBOC signal, and there
may be up to four possible modes of operation that may be used in a typical IBOC system including a backup
mode.
1. FM: Analog RF only. This could be the analog backup mode used during a digital failure.
2. HD: Digital RF only. Used for Separate combining.
3. FM+HD: Analog and digital (at a variable ratio) RF. Also used for common amplification.
4. SLC: Analog and digital (at a variable ratio) RF. Also known as Split-Level Combining. A "Feature Key"
must be purchased to enable this feature.
Using pull-down menus, both the main and auxiliary outputs can be configured with different signals. An Exciter
that has the optional Exgine board and dual D/A converter and dual D/A filter boards has the most flexibility on
output configuration. Refer to the table below. On the upgraded Exciter with Exgine, the main path can be
configured for FM only, HD only, FM+HD or SLC FM modes. For each of those modes, the auxiliary pull-down
windows will configure to the allowable choices listed below.

FM Main output mode
The FM only output is used for analog FM broadcasting only. The dual FM mode (FM on Main and on Auxiliary
output) is used for dual-transmitter operation. For high level combining FM Main and HD Aux is selected. Use of
the aux output with any signal other than the same as the main requires dual D/A converter and dual D/A filter
boards.
•
HD Main output mode
The HD only mode is for stand alone HD operation. HD Main and HD Aux is selected for dual-transmitter HD
operation. Use of the aux output requires a dual D/A filter board.
•
FM+HD mode
FM+HD mode is used for low level combining, common amplification or dual-transmitter low level combining.
The HD carriers are typically 14 - 20 dB below the analog carrier and are adjustable.
•
SLC mode
FM on the main and FM+HD with various ratios on the auxiliary would be used for Split Level Combining where
there is an FM transmitter and an FM+HD transmitter combined with a high power combiner. Use of the Aux
output requires dual D/A converter and dual D/A filter boards along with a Boost Pro amplifier. The feature key is
on a label on the side of units shipped with this feature enabled.
Pilot injection level adjusts the 19kHz pilot injection.
HD Injection level sets the ratio of the HD carriers to the FM carrier.

Section 3 Operation
Diversity Delay (HAX Option)
When utilizing the HAX option, the delay must now be accomplished at the transmitter site by an outboard
processor, or by the HDx-FM exciter itself. Since a portion of the MPS delay is accumulated by the Exporter
coding and transmission architecture, only 3-4 seconds (typically 3.547 seconds - will vary from system to system)
of analog delay will be required.
NOTE:
If the HAX hardware is not installed, these parameter windows will be greyed out, and the following adjustments will not be possible. See Figure 3-11, above for HAX Option setup.
Diversity Delay: Enabled/Disabled - Enable to create the Diversity Delay within the HDx-FM exciter.
Ramp Time (seconds): Range is 1 to 1800 seconds - The audio diversity can be, in essence, turned ON
and OFF using the Ramp Control buttons. However this does not abruptly turn ON and OFF - it sweeps
between 0% to 100% of the programmed Delay Target. When Ramp Up is pressed, the delay is
incremented from OFF to ON or 100% of the Delay Target setting. When the Ramp Down is pressed, the
delay will gradually decrease until there is no delay present, or 0% of the Delay Target.
NOTE:
The longer the ramp time is, the less noticeable will be the pitch-shifting effect of the ramp. When
first setting up the system, a ramp time equaling 1 second is recommended to facilitate faster toggling of the delay for testing purposes.
NOTE:
Typically, ramp times of 12 seconds or greater will not affect Arbitron PPM™ watermarking.
Ramp times of 20 minutes (1200 seconds) or more are virtually imperceptible by the human ear,
and values beyond this should be unnecessary.
Delay Target (seconds): Range is 0.00023 to 11.80000 seconds - Delay Target is the alignment value where the
digital audio and the analog audio are aligned in time at the receiver. This will allow a smooth transition at the
receiver under "blend" conditions. With the Diversity Delay enabled, adjust this parameter until the total amount of
audio diversity delay of the analog matches the digital. Several methods of monitoring the digital and audio signals
simultaneously, depending on test equipment, are recommended below.
•
•
•
Using headphones connected to an HDRadio receiver, set the receiver to "dual" (BFO) mode where you can
hear the analog signal in one ear and the digital signal in the other ear. Start with a Delay Target setting of
3.547664 seconds and then adjust until the two signals are as close as possible. This will typically be the most
’mono’ sounding mix of the two signals in the headphones.
Some HDRadio monitors can derive and display a very accurate analog diversity delay value in seconds and/or
samples. Using such a unit, one can simply monitor the station’s frequency, capture the delay duration, note
this displayed value and enter it into the Final Delay window. Repeat these steps to verify correct delay.
Another method would be to use a dual trace scope, digital and analog receiver and a tone source like an Audio
Precision to align the two samples. Monitor an analog demodulated signal and a digital demodulated signal
with each trace of the scope. Send a burst tone from the source, through the transmission system and align the
leading edge of the burst using the same increment, raise/lower procedure mentioned earlier.
3.3.3
RTAC
The HDx-FM Exciter is designed to be able to cope with different signals, (IBOC, FM and IBOC+FM), in different
transmitters (Z’s and tubes), in radically different installations (SLC vs. Separate combining for instance) and with
5/2/12
888-2570-001
3-9
Section 3 Operation
FlexStar™ HDx-FM
several different sampling rates. All of these factors require of a very broad set of system characteristics that both
the algorithm and pre-corrector must cope with for successful operation of the adaptive pre-correction (RTAC).
With all these demands, it is not possible to model and solve all possible combinations using a single set of
parameters. Therefore, simple systems will require fewer parameters while more complex ones will require more.
For instance, to deal with the equalization of a mild output filter is not as much of a problem, and doesn’t require as
many coefficients to equalize as it would be the case of a sharp tune filter. Also the amplifier type can have a lot to
do with these complexities.
NOTE:
The Non-Linear RTAC is automatically applied to whatever exciter outputs which are currently
outputting HD carriers.
3.3.3.1
Non-Linear Coeffiecient Adjustment
For most installations, only the "Non-Linear" coefficient may require adjustment. "Linear" coefficients might
need adjustment if a filter system is involved.
Typically, 3 to 5 coefficients are used to resolve a "memory-less" non linear amplifier/transmitters, which would
typically be a solid-state PA. 6 to 15 coefficients are commonly used to cope with more complicated, "memoryfull" amplifiers, which can occur due to the cavity of a tube amplifier.
NOTE:
Whenever any changes are made to the RTAC settings, one or more "adapt cycles" will occur.
During this time period (5 to 25 seconds), the samples are being captured and an algorithm is
being computed to adjust the output accordingly. If you are watching a spectrum waveform with
no averaging and a fast sweep time, you will actually see the IMD products outside of the digital
sidebands change. There is an Adapt Cycles counter in the Status section of the GUI: Home | Status | Signal Processing | Next... takes you to page 2 of the Signal Processing Status page.
EXAMPLE: NonLin FM+HD Counts: 1084 / 1087. This indicates that there was 1087 Adapt
Cycles and 1084 of them were successful. Slight differences between these numbers are of no
concern. Significant differences indicate an improper setting, a malfunction, or some other anomaly. Error messages 256, 257, 258, 259, 261, 262, and 1024 might be indications of the problem(s)
causing the failure to successfully adapt. (See "6.13 Signal Processing Status Errors" on page 6-8)
NOTE ALSO: If the transmitter is idle for a continuous period while the exciter is running you
will see a significant difference between the two NonLin FM+HD counts. This is because even
when the Transmitter that is being driven by the HDx exciter is off, the RTAC will continue to run
Adapt Cycles. Same holds true for FM only operation—while the Adapt Cycles continue, there is
no HD carrier sample so the counter will count up, but there will be no "successful" updates.
A common sense approach will be to start by using 3 coefficients and wait. If after about 5 "counts" (about 2 - 3
minutes) a sufficient degree of correction is obtained, you’re finished. Consider switching to a higher number of
coefficients if sufficient correction was not achieved.
Although it might appear as if selecting the highest number of coefficients will work as a “snake oil” to all
problems, reality (and theory as well) has shown to be completely the opposite. Selecting a number of coefficient
greater than required, besides making the estimation slower, tends to render coefficients with higher numerical
error and more general instability. This can make the estimation from one run to the next more prone to variation in
results and ultimately instable. Hence the golden rule for the number of coefficients is: Use only as many
coefficients as you need but not more.

The Status and Errors listings indicate what, if any, error incurred during the last execution of that estimation
algorithm. 0 means no errors found, and must correspond to a successful implementation of the calculated
coefficients in software and a corresponding increment of the first counter shown in the Counts field (see next
paragraph). Other values in this field correspond to a coded error whose meaning is explained in the table in the
Troubleshooting section (see "6.13 Signal Processing Status Errors" on page 6-8). Not all errors are critical, some
errors can show up during one pass of the algorithm and not in the next.
The RTAC DSP Counts listings have two numbers separated by a slash representing the value of two counters. The
first shows a count of the successful updates of the pre-corrector, and the second number shows a count of times the
estimation algorithm has run.
NOTE:
Both counters start the last time the particular pre-corrector was taken out of BYPASS, or when
the exciter was last unmuted.
For instance, “NonLin FM+HD Counts 3/4” means that the NonLinear corrector algorithm has executed 4 times,
and three of them were able to successfully update the coefficients in software (since the NonLinear corrector was
last taken out of BYPASS mode, or the exciter was last unmuted). Generally speaking, under normal conditions,
the Counts should be close to similar numbers.
NOTE:
The RTAC continues its adapt cycles even if the transmitter is turned off, but the exciter is
UNmuted. Therefore, in this situation, the Counts numbers may vary significantly. So, if the
transmitter has been turned off for some time, yet the HDx remained on (with the RTAC in
ADAPT mode), you may wish to reset this counter by momentarily placing the RTAC into
BYPASS mode, then switching back to ADAPT to start the counter again; or by momentarily
muting then unmuting the exciter.
Serial In Sync Errs, and Serial Out Sync Errs are for engineering use.

Parameter Listings
Listed below, in alphabetical order, are the parameters found within the various Setup and Status screens. In an
attempt to provide as much information to the end-user as possible, we have listed many parameters below. They
are accurate as of the date of printing found on the front cover of this technical manual. Many of the screens,
sometimes called menus, are intuitive and self explanatory; touch on the window for a pop-up selection or number
pad to change the parameter.
In addition to the listings here, more descriptive information may be available by touching the ?Help tab (see
Figure 3-16 below) on the bottom of all screens.
To the left of the ?Help tab is the On-Air/Mute tab. This is a quick way to mute the exciter from the GUI. Pressing
it will give you a warning and the option to mute the exciter. NOTE: You will be given a choice: OK or Cancel. If
the exciter is currently muted the tab will say Mute.
To the left of the On-Air/Mute tab is the OK/WARN/FAULT tab. It could be your first indication of a malfunction if
it shows anything other than a green "OK". If it is flashing WARN or FAULT as shown in Figure 3-16, below, that
means further investigation may be required. Pressing the tab during either of these two active indications will take
you to the home GUI screen of the faulty process or board. You may have to press the Right arrow button (upper
right hand button) to locate the actual page with a further warning (yellow) or fault (red) text indication.

Overall System Theory
The FlexStar Exciter contains several boards with specific functions. Overall descriptions are given here.
The exciter has two basic input devices; the XLR Input/output board and the BNC input/output board. These
provide input signals to the FPGA on the Signal processing board. The Signal processing board has the main FPGA
and the FM modulator on it. The HD modulator is on the Exgine card which is an optional add-on module that will
expand the exciter to be capable of HD modes. The output of the FPGA is a complex I and Q which goes to the D/
A module where it is interpolated and upmixed to channel. The analog output RF is then sent to the D/A Filter
board for filtering and amplitude control.
The Exciter has two outputs; Main and Auxiliary. Both outputs can be switched via the front panel or remotely to
FM, HD or FM+HD.

Signal Processing Board and Motherboard
The FlexStar Signal Processing board performs all communications, control, monitoring and signal processing in
the Exciter. The Signal Processing board serves as a motherboard in the FlexStar exciter. The board interfaces to all
the boards in the exciter. Located on the Signal Processing board is the micro-controller, memory, main FPGA and
the FM modulator. The XLR and BNC boards provide input to the FPGA, the PLL provides for frequency up
conversion. The optional Exgine board is used only for HD operation and provides the modulated HD data to the
FPGA. The output of the FPGA is a complex I & Q intermediate frequency that goes to the D/A module and filter

board. They provide the filtered, on-channel output for the auxiliary output and for the PA module for up to 55
watts FM output.
Typical everyday communication to the FlexStar HDx exciter is managed through discrete I/O remote control
signals, 10/100 BaseT Ethernet ports and a CAN (Controller Area Network) bus port. The discrete lines connect at
a DB15 Transmitter Interface and a DB25 for remote command and status output lines. The Signal Processing
board and Exgine have two 10/100 BaseT Ethernet ports each. One Ethernet port on the Exgine module, called
Exporter Link, is dedicated for the HD Radio exciter link data with the other ports being used for setup, code
updates, and general communication. The CAN bus is used to interface to FlexStar Boost Pro units in multitransmitter systems, and/or if a second (optional) HDx exciter is utilized.
The microcontroller on the Signal Processing board performs all housekeeping tasks of the Exciter, including boot
loading, monitoring and reporting, external communications and overall control. Operating at 172 MHz, the
harmonics are well outside the FM band and easily filtered. The microcontroller initiates all communications to the
modulator DSP and the FPGA via the host port interface (HPI) bus. External memory for the micro is provided via
Flash and SDRAM chips.
Remote I/O and Transmitter I/O interfaces to/from the exciter are provided on 25 pin and 15 pin D-Sub connectors
respectively located on the Signal Processing board. In addition, an N+1 connector is located on the Signal
Processing board.
Power for the digital boards in the exciter is derived from a +5VDC supply input to the Signal Processing board. A
DC/DC converter on the Signal Processing board will output +3.3VDC @ 3A max for use on the Signal Processing
board. +5VDC & +/-15VDC are distributed to the BNC I/O Board, XLR I/O board, PLL Board, and D/A Filter
board through multi-conductor ribbon cable interfaces

DSP Modulator
The main function of the DSP modulator is to input FM, SCA1, SCA2 and RDS signals, and output baseband I and
Q signals. All FM modulation takes place in the DSP Modulator creating digital baseband and applying that to a
numerically controlled oscillator (NCO). The output is sent to the FPGA at 774.1875K samples per second.
Figure 4-3 DSP Modulator Functions
4.1.1.1.1 RealtIme Adaptive Correction
The modulator DSP utilizes a Realtime Operating System (RTOS) to schedule the FM modulation task. Once the
FM signal generation task is completed the modulator DSP utilizes spare cycles to run the realtime adaptive
correction (RTAC) algorithm. The purpose of the RTAC is to linearize the output of the amplifier by taking
samples, before and after amplification, comparing them, and altering the amplifiers input to compensate for the
non linearity..

XLR I/O Board
The XLR board in the exciter is used to input the Left and Right audio channels, SCA 1 and SCA2 audio channels,
and redundant balanced AES/EBU channels. The main left (mono) and right analog channels enter on standard
female XLR connectors are filtered then digitized prior to going to the FPGA.
The primary and backup AES/EBU channels also enter on standard female XLR connectors, then are sample rate
converted. The backup AES input uses the main right analog connector. The active state is selected by a relay that
is controlled by the Signal Processing board chip. The digital inputs are terminated, multiplexed, received and
asynchronously sample rate converted prior to going to the FPGA.
There are two SCA inputs on one 5-pin female XLR connector. These inputs are also digitized before going to the
CPLD.
The CPLD passes the three digital audio streams; analog left and right, AES and SCA to the Signal Processing
Board FPGA.

Detailed Description; XLR I/O Board
Audio inputs are available to allow the user to input audio. There are four analog inputs and two AES/EBU stereo
digital input provided. The analog inputs are; Main Left/Mono, Main Right, SCA1 and SCA2. The two digital
inputs are Primary AES and backup AES.
The analog to digital converters digitize the analog inputs. The A/D output sampling rate is defined by the digital
audio clock rate of the Exciter and set to 1/16 of the 744.1875 kHz master sample rate, or 46.5117 kHz.
5/2/12
888-2570-001

Section 4 Theory
FlexStar™ HDx-FM
The differential AES/EBU signals are converted to single ended signals through the isolation transformers and are
sent to the multiplexer used to select primary or backup AES. It is then asynchronously sample rate converted to
match the digital clock rate of the exciter, 46.5117kHz.
The CPLD on the XLR board is the control center of the XLR board controlling the audio inputs applied to the
Exciter. The CPLD also receives control and sends status to the Signal Processing board. The CPLD receives the
digitized analog audio, digitized SCA and the AES data streams and retransmits them to the Signal Processing
board’s FPGA.
4.1.3
BNC I/O Board
The BNC I/O board has 2 functions in the exciter: First is to consolidate the input composite and SCA modulated
audio inputs into one scaled combined input. Then convert this to digital for serial download to the Signal
Processing board FPGA. Second, is to multiplex the RTAC Sample RF inputs for use with the adaptive pre
correction and built-in-test.
4.1.3.1
Modulated Inputs
The BNC I/O inputs are wide band composite audio, two dedicated modulated SCA channels and a dual purpose
channel for either an alternate modulated SCA or unbalanced wide band composite input. The inputs are filtered,
scaled, combined, digitized and sent serially to the Signal Processor board FPGA for the FM modulator. These
inputs have a +/-6dB input range electronically controlled from the front panel.
The Main composite input allows for pre-modulated and combined stereo audio plus the SCA channels up to
100kHz bandwidth. This input is balanced with 10k/50 ohm line to line resistance. It can be configured for
unbalanced or balanced from the front panel. When the auxiliary composite input is selected, the main composite
input is out of circuit. The auxiliary composite input is fixed unbalanced 10K ohm input impedance.
The SCA1 and 2 inputs allows for injection of SCA channels with a bandwidth from 53kHz to 100kHz. They are
high pass filtered and gain adjusted.
The Aux Composite/SCA3 input is a dual purpose input that is configurable from the front panel.
4.1.3.2
RF Samples
The BNC board also has a 4 to 1 RF multiplexer used to multiplex 4 RF input channels into a single output with a
gain adjustment on it. This multiplexed output goes to the Signal Processing board’s FPGA. These four signals
include; two from the RTAC RF sample inputs; transmitter and filter, for linear and nonlinear correction estimation,
and two internal samples from the DA filter board and Exciter PA for real time monitoring and built in tests.
4.1.4
N+1 Interface
The N+1 interface connector allows the user to change the exciter to any of 8 pre configured channels. This is
primarily used for hot standby applications. The interface includes 8 channel command inputs and 8 channel status
outputs. To interface with next generation N+1 controllers the connector also includes an RS232 port.
4.1.5
1PPS Interface
The 1PPS input is used for Pilot sync in single frequency FM networks. The 1PPS input synchronizes all
transmitters in the network to a common input such as GPS. Since the 19kHz pilot is internally generated by the
Modulator DSP, the 1PPS interrupt will be supplied to the DSP. The DSP synchronizes the pilot to 0o phase when
the interrupt occurs. So if the pilot has drifted ever so slightly, it will be reset. All transmitters in the single
frequency network will then have their pilots synchronized and receivers tuned to that frequency can go from one
cell to the next with out interruption.

FlexStar™ HDx-FM
4.1.6
Section 4 Theory
19kHz Output
The FM 19kHz stereo pilot signal is generated in the Modulator DSP as part of the FM modulation. The DSP
provides pilot samples to the FPGA to allow synchronization of external RDS/RBDS equipment to the pilot signal.
The FPGA uses the sample data to drive the Sampling Stereo Audio D/A Converter. The 19kHz pilot signal from
the audio D/A converter is then buffered and goes to a BNC connector on the rear panel of the exciter.
4.1.7
Exgine Module
The Exciter Engine (Exgine) board is used to modulate HD radio data that is received on the dedicated Exporter
Link. The Exgine board also passes through any received FM radio data to the Signal Processing board.
Communication with the Exgine is managed via two 10/100 BaseT Ethernet ports (one of which is intended to
serve as the FM+HD Radio Exporter Link) and an 80-pin interface to the Signal Processing board.
4.1.8
1/4 VGA
The 1/4 VGA screen is a touch screen and an LCD in one unit. The Touch Screen is integral with the LCD. No
hardware adjustments are required.
All setup and configuration can be performed from the 1/4 VGA screen. The user adjustments are performed on the
from panel and include; touch screen calibration, screen saver time-out, contrast adjustment, time and date on front
panel.
4.1.9
PLL
The main purpose of the PLL board is to supply a locked frequency master clock signal to the D/A module board.
The master clock for the signal processing FPGA in the exciter is also developed by the PLL board. The master
clock frequency is from 416.745MHz to 482.2335MHz depending on the carrier frequency and interpolation rate
set. The PLL can be synced to an external 10MHz reference input, or be synchronized to the Exporter Link
interface.
The external 10 MHz reference input is first amplified and put through an AGC loop for level stability. This signal
is then low-pass filtered and squared before being applied to one loop in the PLL chip. The signal is also detected
after the low-pass filter.
The main loop for the PLL has a filter loop made up of a varactor, pin diodes and an oscillator which runs at 416 482MHz signal that is locked to the internal 59.535MHz signal. This frequency feeds back into the PLL chip and is
also buffered and goes to the output for the D/A module board to clock the D/A chips.
4.1.10 D/A Module
The FM, HD, or FM+HD analog on-channel signals are generated by the D/A Converter Module. The D/A receives
a complex baseband signal, in the form of a 16 "I" bits and 16 "Q" bits from the Signal Processor board. The D/A
converter interpolates the digital data and creates a differential analog voltage that is then converted to a single
ended signal that is sent to the D/A filter board.

888-2570-001

Section 4 Theory
FlexStar™ HDx-FM
Figure 4-6 Dual D/A Module Simplified Diagram
The D/A module is clocked by the Master PLL clock from the PLL board at 416 - 482 MHz (for better spurious)
depending on carrier frequency and interpolation rate. For split-level combining or when two outputs are required,
the dual D/A Module is used (shown above). Others will have a single D/A circuit. In the dual D/A boards the
converters are synchronized by monitoring the clock output of each D/A converter. Each of the two RF outputs, in
split-level configuration will drive different transmitters, the outputs of these transmitters are combined and need to
be in-phase with each other. To monitor this the D/A converter clock signals are monitored and if out of tolerance,
the converters are reset. The clock signals are applied to an AND gate, if they are in-phase the output of the AND
gate is the maximum voltage of 1.65 volts. If the clock outputs are out of phase 180o with each other, the output is
0 volts. If they are out of phase by 90o or 270o the voltage is one half the maximum, or 0.825 volts. So the level of
voltage out of the AND gate will report the degree of phase mis-match. When the phases are to far out of tolerance,
the Signal Processing board will reset the DAC’s until they are in-phase.
The Main output at J5, and the Aux. output at J4 are both 50 ohm.
4.1.11
D/A Filter Board
The main purpose of the D/A filter board is to eliminate the image signal and spurious artifacts resulting from the
high speed switching of the DSP module board. Once the DSP Module generates the on-channel signal, the D/A
Filter Board takes the output from the high speed DSP, filters and amplifies the signal eliminating images and
spurious artifacts outside the desired bandwidth. The D/A Filter board contains a +/-2MHz wide tracking filter, of
which the center frequency can be set from 88MHz to 108MHz, and tracks with carrier frequency. The D/A filter
board also provides the system with a variable attenuator to adjust the amplitude of the signal independent of the
DSP output level. In the case of split-level combining, dual transmitter or separate amplification, it may require up
to an optional Dual D/A filter board with two filter circuits; one for the Main output and one for the Auxiliary
output.
4.1.11.1
Detailed Description: D/A Filter Board
The RF input comes from the D/A module output and is applied to a 1.5dB pad and is then split. One output of the
splitter goes to a switch that terminates the unused input for better isolation. The purpose of this switch is to
4-8
888-2570-001
5/2/12
Section 4 Theory
FlexStar™ HDx-FM
configure the Auxiliary output with the same input as on the Main or from the Auxiliary input. After this switch,
both circuits; Main and Auxiliary function the same.
After the input splitter the RF goes through a band pass filter tuned for 88 - 108 MHz. The output of this filter is
applied to a 2 pole varactor tuned band pass filter. Each of these varactor stages is controlled independently by the
Exciter via data stored in the EEPROM to affect the waveform response of the output. The desired result is for
+2MHz and -2MHz to be within +/-0.1dB of each other. After these varactor circuits the RF goes through a
variable attentuator for the final output level control. A directional coupler takes a -10dB sample padded and
amplified to increase the isolation. The sample is for the BNC board to use for a monitoring sample.
4.1.12 PA and Low Pass Filter
The power amplifier is in the main output path of FlexStar HDx exciter. It is used to amplify either FM or HD or
mixed FM+HD signal. It also generates samples of forward and reflected power, PA voltage and current, bias
voltage reading as well as heatsink temperature.
The output power will depend on what mode the Exciter will be in; FM, HD or FM+HD. The PA module runs in
tri-mode, or three different biases; class A, AB, or C. Bias on the amplifier changes when the mode is changed.

The amplifier contains 3 stages of amplification. The first stage operates in Class A operation mode. Class of
operation of following 2 stages depends on modulation of amplified signal and transmitter configuration.
The first stage operating in class A contributes 15dB Gain. The stage includes input and output matching circuits.

Section 4 Theory
FlexStar™ HDx-FM
The next stage delivers up to 6W. It contributes about 15dB gain. The class of operation is controlled by the binary
level control signal that comes from system controller through J7-17. Low level control signal will disable class A
current loop and transistor operates in class AB. The bias current in this mode is set by the potentiometer R14 to
make voltage reading at TP3 = 1.0V. High level (+5V) control signal will activate the current loop organized by
current sensor R12, difference amplifier U3 and operational amplifier U7.
The final stage is based on two MOSFETs working in push-pull configuration. Gain varies from +15dB in class A
to 10dB in class C mode of operation. Output power is limited to 60W in compression. A balun transformer
provides a broadband impedance match between the Driver and final stage. Output matching circuit includes a 1:4
transformer and balun transformer.
Class A is activated by receiving high level from J7-19 provided by system controller. If the control level is low the
class of operation can be either AB or C depending on control level on J7-17. High level on pin 17 corresponds to
class AB, low level on pin 17 corresponds to class C.
The output Low Pass Filter (LPF) is designed to reduce harmonic emissions.

Preventative Maintenance
The FlexStar® HDx Exciter should require very little servicing. Extensive digital processing within the exciter
eliminates most causes of drift and ensures stable performance throughout the life of the product. As with any
electronic equipment, the reliability of it is enhanced if it is kept clean and cool.
5.2
Cleaning
!
DANGER:
REMOVE THE POWER CORD FROM THE POWER SOURCE PRIOR TO SERVICING THIS UNIT.
Inspect the intake air fan and the interior of the FlexStar® exciter periodically. Look for dirt deposits, particularly
on the PA heatsink, and clean out any dust or dirt which has collected. If dirt build-up occurs, consider adding an
intake filter to the cooling fan. Accumulated dirt is the enemy of efficient cooling.
During the inspection, check to see if the fan is turning freely and quietly. Like any moving part, the cooling fan
will become worn after a long period of operation and will need to be replaced. Doing so before the fan fails will
ensure against outage.
5.3
Cooling
Try to do the cleaning and inspection of the exciter as soon as possible after sign-off and check for elevated
temperatures inside. Excessive temperatures are the enemy of reliable operation. If you note signs of excessive
temperature, check to see that the exciter receives an adequate supply of cooling air and that the exhaust from the
right-hand side can flow away from the exciter without being blocked.
5.4
Fine Frequency Adjust
For fine frequency adjustments, only when the exciter is not synchronized to the external 10MHz or Exporter link,
go into the Advanced Setup pages. Locate the PLL TCXO and change the numeric value slightly.
5.5
Periodic Exciter Alignments
There is no recommended periodic alignment for the Exciter. It has been fully aligned and tested at the factory
during manufacture. Very few adjustments should be required subsequently other than operational settings.

and time, and is located on the Controller board (main board behind front panel of unit). To attain access to the
battery’s location in order to replace it, place the unit on a flat surface and remove the front panel.
5.7
STEP 1
See "5.7.2.1 Remove Top Cover & Front Panel" on page 5-4 for directions to access the
Controller board. See also Figure 5-1 on page 5-5)
STEP 2
Use caution when sliding the battery in to avoid bending the spring clamp piece of
metal that holds the battery down in its receptacle.
STEP 3
Replace the lid and front panel before reapplying power and reinstalling it into the
rack.
Board Replacement
!
DANGER:
Most of the boards in the Exciter are horizontally oriented. If you have to remove any boards from the Exciter for
replacement or service, access is through the front of the Exciter.
Power down the Exciter before removing any boards or wiring connectors from the boards. Ensure a clean and
static free environment before servicing the boards and wear a ground strap before touching any internal
components.
Start by removing the top panel of the Exciter. Then the front panel is removed by removing screws on the side and
bottom holding the front panel on. The cabling is long enough to allow the front panel to lay down, still connected
to the Exciter so you can operate the Exciter and have physical access to the boards for troubleshooting.
!
CAUTION:
ALWAYS POWER DOWN THE EXCITER WHEN REMOVING OR INSTALLING
ANY BOARD OR CABLE.
See section "5.7.2.1 Remove Top Cover & Front Panel" on page 5-4 for a detailed step by step procedure.

Software Upgrade
Changing the Signal Processor (Main uP) software version in the Exciter can easily be performed using the USB
port on the front of the Exciter or an Ethernet cable on the rear of the Exciter. The Exgine can only be updated via
Ethernet.
NOTE:
DO NOT use a USB jump drive that has been formatted with Linux operating system (like in the
DEXSTAR Exciter). It may cause the FlexStar to hang while searching for a file structure. Reformat to Windows before using with the Exciter.
Care must be taken during any upgrade:
•
•
Be sure that the Exgine updates are sent to the Exgine; and Signal_Proc updates are sent to the Signal processor. Updating a component with the wrong file will render the exciter inoperable and require factory service to
repair.
Take care to minimize extraneous traffic during the Exgine/Signal processor update. Consider using a simple
switch or a hub to connect the source PC with the Exciter Link and one of the maintenance Ethernet ports with
no other connections to minimize latency. The Exciter has little tolerance for network delays during this process and will give a browser (404) error if the update data is delayed. If this happens minimize network issues
and try again in a new browser window.
IT IS RECOMMENDED THAT THE FOLLOWING UPDATE ORDER BE OBSERVED:
1. Update the Exgine first
2. Then update the Signal processor
5.8.1
Update Exgine Using Ethernet
This procedure is for the Exgine software update only.
IMPORTANT:
READ THESE INSTRUCTIONS BEFORE ATTEMPTING THE UPDATE
!
STEP 1
Download the Exgine software from the Harris Customer Premier website. The actual
file name will be similar to “exgine_host_230.s19”. This example is version 2.30. The
file may be located on hard drive or USB flash drive.
STEP 2
Connect standard Ethernet cable from exciter’s Exporter Link to LAN or directly to a

LONGER FUNCTION AND REQUIRING THAT THE EXCITER BE RETURNED TO
HARRIS FOR REPAIR.
STEP 3
Apply power to the Exciter if it is not already running. It is suggested to use a UPS
during this process.
STEP 4
Go to the Serial Setup 2/3 Page on the front panel LCD. Make sure that either Exciter
Link or Ethernet #3 has a valid IP address. When STATIC is selected you must be
using a valid address for your LAN. If DHCP is selected your LAN must serve an IP
address to the exciter. Most installations will use static IP.
STEP 5
Use a PC which is on the same LAN as the Exciter (set PC to static address on same
network as exciter or use DHCP if available). Open a web browser window (i.e.
Internet Explorer) on the PC.
STEP 6
In the address bar of the browser, enter the IP address of the Exciter Link or Ethernet
#3. You should see “HARRIS FlexStar” and “Exgine HD Processor” at the top of the
page.
NOTE:
THE HD SIGNAL WILL BE LOST FOR ABOUT 20 seconds DURING THE REBOOT.
STEP 7
In the box “File to Update:” browse for the “exgine_host_XXX.s19” file from step 1
then select “Submit”. The screen will display “Uploading file…”, then “Module must
be programmed to complete the update”.
STEP 8
Click the “[PROGRAM]” button. This will program the Exgine flash memory and
reboot the application. This programming and restart process takes about 2 minutes
total.
STEP 9
Click “HOME” or close the browser after the reboot is complete.
STEP 10 On the exciter press the “Status” soft key on the touch panel to go to the Exciter Status
page. Then press the “S/W Revs” soft key to display the software revisions. Verify that
the Exgine uP revision is correct.
STEP 11 Return the exciter to normal operation.

This procedure is for the Signal Processor software update only.
IMPORTANT:
READ THESE INSTRUCTIONS BEFORE ATTEMPTING THE UPGRADE
5/2/12
STEP 1
Download the FlexStar Exciter software from the Harris Customer Premier website.
The actual file will have a name similar to “flexstar_ver_5_8.s19”. In this example the
version is 5.8.
STEP 2
Copy the downloaded s19 file to a USB 2.0 flashdrive and name the file “flexstar.s19”.
Exit from your windows explorer and then click the Safely Remove Hardware button
in the PC’s taskbar. Remove the USB flashdrive from the PC’s USB port.
STEP 3
Apply power to the Exciter. It is suggested to use a UPS during this process.
STEP 4
Navigate to the Exciter’s USB Setup page.
888-2570-001
5-9
FlexStar™ HDx-FM
STEP 5
Insert the flashdrive into the USB port on the exciter front panel.
STEP 6
Verify that, after a few moments, the device status is “Connected” and that to the right
of the S/W Upgrade button that it indicates “Ready”.
NOTE:
The exciter will automatically restart near the end of the update process. RF OUTPUT WILL BE
LOST DURING THIS RESTART. Stop now if that will be a problem. The process takes about
20 minutes, and then it will restart. DO NOT interrupt AC power to the exciter or press any buttons during the update process.
STEP 7
Press the S/W Upgrade button. The screen will change to the Software Upgrade from
USB page.
STEP 8
Press the UPGRADE button to begin the update process (or CANCEL to return to the
USB Setup page). The approximately 20 minute process has now begun. It will take
about 10 minutes to load in the entire file from the USB flashdrive. Then the file is
automatically written to the exciter’s internal flash memory. This will take an
additional 10 minutes. When the flash programming is complete the exciter will restart.
THE RF OUTPUT WILL BE LOST DURING THIS RESTART.
STEP 9
After the exciter is running again press the “Status” soft key on the touch panel then
press the “S/W Revs” soft key to display the software revisions. Verify that the Main
uP S/W Revision has been updated.
STEP 10 Unplug the USB flashdrive and store in a safe location.
STEP 11 Return the exciter to normal operation.
5.9
Power Calibration Adjustment
You will need a calibrated external power meter, and a 30 dB attenuator to protect the meter and a 100 watt load for
the Exciter.
1. On the exciter, navigate to the (Setup, More Setup, Power Cal) screen. Follow the on-screen directions to calibrate the Exciter’s main RF output power.
2. Using the up/down arrow buttons on the screen, first set the output power, as read on the external meter, to 50
watts and "Accept." Then using the up/down arrows on the screen, set the output power as read on the external
meter to 1 watt. "Accept."
5.10 Record Your User Settings
Use these screens with the settings blanked out to record your user settings in all the parameter windows. In the
event you restore the factory defaults and you do not have your user settings that were saved on the jump drive, you
can manually enter this information that you have written into the Exciter.
You can also capture your screens as bitmaps using the USB port on the front of the FlexStar HDx-FM Exciter.
These can be stored on one or more computers, CDs, external harddrives, or cloud drives.
STEP 1
Plug a USB flash drive into the port on the front panel.
STEP 2
To verify the USB flash drive is recognized by the HDx exciter, navigate to the USB
Setup page:
• Press Home
5-10
888-2570-001
5/2/12

• Press Setup
• Press USB
• Device Status: should read Connected. If it says Removed then the
USB drive is not being recognized by the controller. Repeat with a different jump drive.
STEP 3
Navigate to the screen you wish to capture.
STEP 4
Press the Harris HD Radio logo on the upper left corner of the page. A message box
will open: "Store BMP of this page to USB Flash Drive?"
STEP 5
Press the OK button.
STEP 6
Wait for about 15 - 30 seconds, and the following message box will appear: "Screen
Dump Complete"
STEP 7
Remove the flash drive from the front panel.
STEP 8
Plug flash drive into a computer.
STEP 9
Navigate to the flash drive’s files.
STEP 10 Copy the file called scrndump.bmp to a folder at a location you will remember.
STEP 11 Rename the file to represent the screen you just captured.
Example: InputSetup1-5.bmp to represent Input Setup page 1/5.
STEP 12 While it is still connected to the PC, delete the file called scrndump.bmp from the flash
drive in order to be able to save another screen.
STEP 13 Remove the flash drive from the computer.
STEP 14 Plug the flash drive into the front panel USB port.
STEP 15 Repeat STEP 3 through STEP 14 for every screen you wish to save.
NOTE:
This process will only create a file called "scrndump.bmp". So after you have copied it to a PC—
and you want to save more than one menu page—you will need to repeat the above steps for each
screen. (Having your call letters in the header of each page will help identify the information at a
later date. Do this on the Setup | Display screen and enter your call letters in the page title line.)

6.2
Common Service Issues
Below is a listing of the top reasons for calls to the Harris Service Department. Please review this before placing a
call to the Service group. Some of these involve the HDE-100 Exporter (see "6.1 Top Service Issues" on page 6-1
of the Exporter technical manual for details) or the HDI-100 Importer.
NOTE:
6.2.1
PLL Sync
If you experience periodic dropped HD Carriers or drifting Analog Diversity Delay, verify that the PLL Sync
(Home | Setup | More Setup | Page 2/4) setting in the HDx GUI screen is set to EXPORTER, at the very least. When
set to EXPORTER, the HDx uses time frames from the E2X stream to synchronize, and no other clock connections
are required. The INTERNAL setting is never recommended.
If you are able to use some kind of a GPS clocking system, or have the Exporter co-located with the HDx, you
should then be using the EXT 10MHz selection. Using a BNC cable from the 10MHz REFERENCE IN, on the
HDx rear panel, connect to the Exporter’s CLOCK 10MHz output, or to your GPS system’s 10MHz reference
output. This would be the preferred method.
6.2.2
Service Mode & Passwords
It is strongly recommended to change Service Mode (MP1, MP3, MP11, "Dynamic", etc.) settings via the
Importer, if used. This Mode selection is based on your configuration, however, "Dynamic" should always be
checked. And, again, this selection should always be made through the Importer interface, and you will need to resynchronize the exporter upon a service mode change.
NOTE:
Default password to get to System Settings in the Exporter is "1234".
If you are using the VNC application in the Importer to access the Exporter, that VNC password is
"password".
To access the WebAdmin application in the Importer, the password is "admin".

6.2.3
FlexStar™ HDx-FM
GPS Receiver Issues
If you suspect the Exporter’s (HDE-100) built-in GPS receiver of a malfunction, it may simply need to be reset.
However, this is only done by completely powering OFF the exporter for greater than 10 seconds.
6.2.4
Signal Processing Fault
If 3 or 4 of the following status lines in the Signal Processing Menu, page 3/5, show FAULT, the most likely cause
is a failure of the E2X communication between the Exporter and the HDx exciter (see section "6.3 No
Communication" on page 6-3 for more information).
•
•
•
•
HD Run
HD Buf
DSP Run
EL Run
Possible causes of this connection failure could be many things depending on the path between the HDE-100 and
the HDx. First things to check would be the "Exporter Link" IP Settings in the HDx GUI: Home | Setup | Serial |
Page 4/4.
Under some circumstances, the Exporter Link address in the HDx GUI, can revert to the factory default of
127.0.0.1. If communication has been lost between the exporter and HDx, check this setting to be sure it is set with
your LAN IP addresses. Also, be sure this link mode is configured as Static, not DHCP
Other possibilities, could be the Cat 5/Cat 6 cables have become disconnected, failure of a switch or router, LAN
failure, STL path failure, etc. The final step in troubleshooting would be to revert to factory IP settings and directly
connect the exporter and exciter back-to-back. See "2.5 Quick Start - Bench Test" on page 2-3.
6.2.4.1
UDP vs. TCP
If you are using a unidirectional STL for the E2X stream, the UDP protocol must be used, and the MAC address of
the HDx exciter’s Exporter Link (found in the HDx GUI at Home | Setup | Serial | Page 4/4) must be input to the
Network Configuration screen of the HDE-100 Exporter (see Figure 6-2 on page 6-3)
MAC Address

Exciter MAC Input
Figure 6-2
Exporter Network Configuration Screen
(Home | System | Network GPS)
Typically the Exciter’s Exporter Link MAC address will need to be input when using UDP. In the above graphic,
TCP is the current selected mode. Using the MAC address in TCP mode is not recommended, nor necessary.
6.3
No Communication
For difficult to resolve connectivity issues with any of the FlexStar devices, consider reverting back to factory
IP settings and directly connect the Exporter and exciter back-to-back. See section "2.2 Quick Start" on page 2-2.
6.3.1
IP Troubleshooting Tools
There are several free IP capture applications which my prove to be useful for determining IP-related malfunctions.

6.3.2
Check GUI
Always check the GUI first when ever there is a problem. An extensive amount of information is brought to the
Signal Processing board to drive the GUI. First view the GUI to see if it indicates the problem.

6.3.3
FlexStar™ HDx-FM
Check Exporter Link
Whether you have connected this unit to the Exporter either through a network, Internet or STL verify the Ethernet
connections. To verify the Ethernet connection is communicating, look to see if the LEDs next to the connection
port are lit. A green LED indicating a valid link should be lit continuous indicating a good connection, the yellow
LED should be flashing to indicate activity on the line, 3 to 4 times per second.
6.3.3.1
HD RUN, HD Buff, EL RUN, DSP RUN Warnings
These warnings can be caused by configuring the Exciter to HD mode and not having a reliable input from the
Exporter via the Ethernet connection. Check that the Exporter Link cable is physically connected, and sending data
by verifying that the Exporter link connection on the rear of the Exciter has an LED illuminated and one blinking to
indicate traffic. NOTE: This does not indicate that it is actually talking to the Exporter, only that it is connected to
the LAN.
See table 6-1 for Exgine HD faults. Also see "3.4.2.3 "Exgine" (page 3/5; 4/5)" on page 3-16 for more information.
Table 6-1
Exgine HD: "OK" and "FAULT" Descriptions
"OK"
"FAULT"
EL RUN
Exporter Link is receiving data from the
exporter.
No data from the exporter, or wrong
MAC entered into the Exporter screen.
DSP RUN
Exgine DSP is digitally modulating the
HD signal.
Exgine DSP is not doing anything.
Two reasons:
1) There is no data to process (Exporter
Link or Internal)
2) There is something wrong with the
DSP HW or SW.
HD BUF
Buffer of modulated HD is being
utilized.
Buffer is empty, check to see if the
Exciter is in "test" mode.
HD RUN
Exgine is sending a signal to the exciter's
digital upconverter. This may be HD or
just an HD test pattern, depending on
the settings for the Exgine.
Exgine is NOT producing any output
signal.
6.3.3.2
Check Firewall
When going through a firewall, sometimes UDP can get through without stoppage. However, if you suspect the
firewall is the problem, ensure that port 8145 is open for the UDP link.
6.3.3.3
Verify IP Address
If you have used DHCP and the connection was made after the Exciter was turned on, restart the Exciter after the
cable is connected. Then check the DHCP address on the Exciter and verify the one entered into the Exporter is the
same as the one on the Exciter serial setup screen.

No RF Output
First check the PA power supply on the RF System Status screen, if zero volts see the section labeled "PA Volts
Zero, System Control Fault" below.
If that is not it, check the individual boards inputs/outputs for RF. Removing the fasteners on the front cover, and/or
top panel, to gain access to the inside.
With the spectrum display for the main filter output, or with a spectrum analyzer, verify the PA has RF on the
output, first at the PA output connector at the PA (CAUTION: this is 55 watts). Then check the RF input to the PA,
the input will be +6dBm max. Test points on the PA amplifier are accessible from the top, TP 6 is forward power
and should read 3.7 volts when 50W forward power is present (10 watts should read 3.00 v +/- 0.05v).
6.5
No HD Carriers
The HDx-FM exciter will not generate HD carriers unless one of two following conditions are met; it’s in TEST
mode, or NORMAL mode.
6.5.1
Test mode
The HD carriers can be internally generated for initial testing by making the following parameter selections on the
exciter’s Output Setup page;

There are LEDs and test points on the Exgine board. The Exgine board can be removed from the chassis, and
placed on top of the Exciter for bench testing and troubleshooting. Use an insulating layer under any board that you
intend to power up and always use a ground strap on yourself and the Exciter before touching any sensitive boards
or components.
Check the voltages with a digital multimeter and observe the LEDs on the board and compare with the table below.
Diagnostic LEDs LED0 through LED2 should be oscillating, and LED3 should be OFF, LED4 should be ON.

Password Protection
The first time you enter the Display setup screen, the password should be blank, not yet entered into the field. If
you want to lock the setup screens to prevent anyone else adjusting in them, enter your unique password in the
Display Setup screen. Then from most any screen, you can lock the setup screens by pressing the lock icon at the
bottom of the page.
NOTE:
This password should be entered into this field before you lock the setup screens. Failure to do
this will prevent you from unlocking the screens to enter in a password.
In the event that you have lost the password, use "iboc" to gain access.
6.10 Saving Settings
Once good operational settings are obtained, it is recommended to save them off to a USB flashdrive device. Those
settings should also be saved on a PC for redundancy. Saving these user settings DOES NOT save the settings or
MAC addresses on the Serial Setup screens 2/4, 3/4 and 4/4, or the feature key found on the S/W Revisions Status
page. Record those manually in the maintenance section (see "5.10 Record Your User Settings" on page 5-10) for
backup purposes.
NOTE:
Use a dedicated USB jump drive for every unit. DO NOT use a USB jump drive that has been formatted to Linux (like that used in a DexStar Exciter). Inserting a Flashdrive formatted in Linux
can cause the FlexStar Exciter to hang up. Also do not use a USB jump drive from another HDX
Exciter as it will overwrite the files. The FlexStar HDX supports USB 2.0 low speed only.
6.11 Restore Defaults
IMPORTANT:
Pressing this button would be considered as a last operation, if all other troubleshooting processes
have been attempted.
This button on the Exciter Setup screen labeled Restore Defaults will take the entire Exciter, all of its settings,
including the password, back to generic factory parameters. This button will NOT revert back to the same
frequency or settings that it had when shipped to you. It might be used only if during adjustment you get so far out
of normal operational adjustments, or if all troubleshooting processes have been attempted without success.
The next process following "Restore Defaults" would be to restore your settings ("Config #1" through "Config #4"
that should have been saved previously) by using the USB Setup menu.
5/2/12
STEP 1
Insert the USB drive containing the configuration file(s) into front panel USB port.
STEP 2
From the Home screen, press Setup.
STEP 3
Press USB, which will display a page similar to Figure 6-3 below. If there are valid
configuration files stored on this USB drive, there will be a date and time of day
indicating when the configuration file was last saved to the device.
STEP 4
Press the Config # of the desired configuration you wish to make active.
STEP 5
Press Restore and follow the prompts.

6.12 Noise, Tone or Loss of Audio
If an FM receiver is locking on to the carrier, however there is white noise or tone being broadcast and that is not
the audio into the system, check to make sure the FM test patterns are not turned on.
If the receiver when in HD mode has silence, and that is not what is being input to the system, ensure the HD
carriers are being transmitted. If they are, then ensure the HD test patterns are not turned on.
6.13 Signal Processing Status Errors
The table below lists errors associated with the Signal Processor adaptive algorithms, keep in mind not all errors
are critical, some errors can show up during one pass of the algorithm an not in the next. Of course if an error is
consistently showing with a relatively high frequency it should be resolved since it will prevent the pre-correction
to operate with the desired rate and it could be an indication of other problems.
This error number will appear on the NonLin FM+HD Status: row of page 2/5 of the Signal Processing Status
screens. See Error #256, circled in GUI screen example below.

Hardware problem
14
Before the DSP can access the SRMC sample
control in the FPGA it has to wait for it to be
finish with previous access (for instance from
the micro controller ) if the srmc never finish
previous access the DSP has to quit waiting
until a another set of samples is requested
Excluding a handshake problem
between the micro and DSP the
most probable cause is a hardware
problem
On each request of samples by the DSP it
requires from the micro the setting of the
feedback multiplexer to the specific feedback
path. Either the PA output or the transmitter’s
FEEDBACK
filter output. The micro switches the
SAMPLE NEVER multiplexer and sets the correct attenuation to
SET
the sample and returns a handshake indication
to the DSP indicating samples are ready to be
taken. If after a period of 3 second the
handshake ready bit has not been set the DSP
quits waiting without taking samples.
- Excluding a handshake problem
between the micro and DSP the
most probable causes are either
Insufficient or too much feedback
level in the particular sample port.
This prevents the micro of finding
the correct attenuation gain for the
feedback sample path
consequently it never sends a
handshake indication to the DSP
for it to take samples.

Signal Processing Status Errors
Meaning
Explanation
The set of samples taken from the Feedback
FEEDBACK TOO
has insufficient energy to perform a reliable
LOW
estimation. Estimation is aborted
Typical Causes
- Insufficient feedback.
- Presence of an interference
signal with to high energy in the
feedback path.
SOLVER ERROR
NL
In the estimation of the pre-correction
parameters the algorithm found indications of
severe numerical precision errors that could
affect the results. No reliable solution will be
rendered under this circumstances hence the
estimation aborts and the pre-correction
parameters are discarded
- System is severely overparameterized. Reduce the
number of parameters used in the
estimation
DELAY ERROR
During the estimation of the delay from the
reference signal of the exciter to the feedback
signal this is found to be beyond a safe
window. Estimation is aborted.
- Incorrect signal in the feedback
sample to the exciter.
259
CORRELATION
ERROR
During the estimation of the correlation
between the reference and feedback signals of
the exciter this is found to be beyond below a
safe window. Estimation is aborted.
- Incorrect signal in the feedback
path.
- Too high of an interference in the
feedback path
- Exciter output is off frequency
260
UNSUPPORTED
SAMPLE RATE
The DSP has no knowledge of the sample rate
used by the micro
- Handshake problem between the
DSP and micro.
261
Once the pre-correction coefficients have
been estimated, the DSP expects their values
to be in a certain range. If this is not the case
even when the coefficients could in theory
minimize the error of the system (or preCOEFFICIENT
correct the transmitter), it is likely that
OUT OF BOUND because of their magnitude the real hardware
in the FPGA - that has to implement the
corrector - could incur severe rounding errors.
The DSP hence, as a precautionary measure,
discards the coefficient without updating the
pre-corrector.
262
There is not enough modulation level in the
IBOC (amplitude modulation of the total
output signal) to perform a reliable estimation
of the AM2AM characteristics of the
amplifier.

6-10
IBOC LEVEL
TOO LOW
At least one of the corrector coefficients can

COEFF NOT
- The most likely cause is
incorrect (too high) a number of
coefficients for the estimation.
- A spurious condition in the
feedback.
IBOC modulation has not started
