Returning Your Signal Generator for Service
Use the information in this section if you need to return the signal generator to
Agilent Technologies.
Packaging the Signal Generator
Use the following steps to package the signal generator for shipment to Agilent
Technologies for service:
1. Fill out a blue repair tag (available at the end of this chapter) and attach it to the
instrument. Be as specific as possible about the nature of the problem. Send a copy of
any or all of the following information:
• Any error messages that appeared on the signal generator display.
• A completed performance test record from the calibration guide for your instrument.
• Any other specific data on the performance of the signal generator.
2. Use the original packaging materials or a strong shipping container that is made of
double-walled, corrugated cardboard with 159 kg (350 lb) bursting strength. The carton
must be both large enough and strong enough to accommodate the signal generator and
allow at least 3 to 4 inches on all sides of the signal generator for packing material.
CAUTION
Signal generator damage can result from using packaging materials other
than those specified. Never use styrene pellets, in any shape, as packaging
materials. They do not adequately cushion the instrument or prevent it from
shifting in the carton. Styrene pellets cause equipment damage by generating
static electricity and by lodging in the signal generator fan.
3. Surround the instrument with at least 3 to 4 inches of packing material, or enough to
prevent the instrument from moving in the carton. If packing foam is not available, the
best alternative is SD-240 Air Cap™ from Sealed Air Corporation (Hayward, CA
94545). Air Cap looks like a plastic sheet covered with 1-1/4 inch air-filled bubbles. Use
the pink Air Cap to reduce static electricity. Wrap the instrument several times in the
material to both protect the instrument and prevent it from moving in the carton.
4. Seal the shipping container securely with strong, nylon adhesive tape.
5. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to ensure careful
handling.
6. Retain copies of all shipping papers.

Initial Troubleshooting
Perform the following troubleshooting steps in the order they are presented. If you are
unable to identify the failed assembly, go to Chapter 2, “Assembly-Level Troubleshooting
with Block Diagrams,” for further instruction.
NOTE
Do not attempt to replace any fuses within the power supply to correct a
problem with your signal generator. If you determine that the power supply is
the failed assembly, replace the power supply.
Step 1: Observe the Front and Rear Panel LEDs
Observing the LEDs on the front and rear panel of the signal generator will determine if
there is a catastrophic failure in the power supply assembly.
1. Ensure the signal generator is plugged in (do not switch the power on) and verify that
the yellow LED on both the front and rear panels is lit. Refer to Figure 1-1 for LED
locations. A lit yellow LED (+15 V_STBY) indicates that line voltage is present.
2. Power on the signal generator and verify that the green LED on both the front and rear
panels is lit. A lit green LED indicates the power supply has received an “ON”
command. The ON/OFF switch toggles a flip-flop latch which biases the proper
transistors in the LED control circuit. This circuit is powered by VBAT, the
battery-backed SRAM supply, so that the on-off state is “remembered” even when the
instrument is unplugged.
Figure 1-1 LED Locations on the Front and Rear Panels

Service Guide
Step 2: Power On the Signal Generator and Check for Error
Messages
This procedure verifies that the signal generator powers up and that the internal
instrument check identifies no errors. The internal check evaluates the correctness of
operation and returns an error message if a problem is detected.
1. Switch on the signal generator. Let the signal generator warm up for at least five
minutes.
NOTE
For ESG-AP, ESG-DP, and Option 1E5 signal generators, ERROR 514,
Reference Oven Cold will occur whenever the signal generator is powered
up within five minutes of being connected to AC line power. The OVEN COLD
annunciator and the ERR annunciator will both turn on. The OVEN COLD
annunciator will automatically clear after approximately five minutes. The
error queue cannot be cleared, however, until the OVEN COLD annunciator has
turned off.
2. Cycle the power to the signal generator and verify that the green LED on both the front
and rear panels is lit. Refer to Figure 1-1.
3. When the display is lit, check to see if the ERR annunciator is turned on.
4. If the ERR annunciator is turned on, review the error messages in the queue by pressing
Utility > Error Info > View Next Error Message. The first error message in the queue will be
shown in the text area of the display. Refer to the Error Messages guide for descriptions
of error messages.
If there is more than one error message (each message will be designated as 1 of n),
continue pressing the View Next Error Message softkey until you have seen and recorded all
of the messages.
5. If you were able to resolve all of the error messages, press Utility > Error Info >
Clear Error Queue(s) to delete the list of error messages.
Service Guide
1-13
Step 3: Functional Check the Front Panel Keys and Display
1. Press various front panel hardkeys and softkeys to verify they function as expected.
2. Use the contrast keys to verify that the display can be lightened and darkened. Refer to
Figure 1-2.

Service Guide
Step 4: Visually Check the Individual Voltage Supplies
1. Unplug the signal generator and remove the instrument cover. Refer to Chapter 5,
“Assembly Replacement,” for removal instructions.
2. Expose the motherboard by removing the top cover. It is secured by 11 screws.
3. Plug in the signal generator and allow it to warm up for at least five minutes.
4. If possible, clear the error queue(s) of messages. Press Utility > Error Info > Clear Error
Queue(s).
5. On the motherboard, locate the 10 LEDs that correspond to the individual voltage
supplies (see Figure 1-3). Verify that all the LEDs are lit. If one or more LEDs are off,
proceed to “Step 6: Isolate the Failed Assembly”.
Figure 1-3 LED Locations on the Motherboard
Service Guide
1-15
Step 5: Measure the Individual Voltage Supplies
The voltages supplied as inputs from the power supply via J6 to the motherboard are
+15 V (TP502), +15 V standby (+15 V_STBY), −15 V (TP503), +12 V (TP505), and
+5.2 V (TP302). DGND (TP301) is associated with these supplies.
The −6 V (TP508) and −5.2 V (TP509) supplies receive their input from the +5.2 V digital
supply (5.2 VD at TP506). The +5.2 V digital line is filtered to prevent the switching power
supply noise from being induced onto the +5.2 VD supply lines. The −6 V is a bias voltage
for circuits on the output board and other RF circuitry. The −5.2 V is used by the emitter
coupled logic (ECL) digital ICs. The LCD display driver voltage (VLCD), a −14 V to −24 V
source, also receives input from the +5.2 VD supply.
The input to the +32 V supply (TP504) is the +12 V supply. The +32 V supply is used by the
synthesizer/doubler assembly. This supply also includes an LC noise filter.
The +12.5 V regulated supply (TP510) originates from the +15 V input. The −12.5 V
regulated supply (TP511) originates from the −15 V input. These two supplies are used by
the solid-state attenuator and the reverse power protection (RPP). The +10 V reference
(TP501) originates from the +15 V input. The +9 V supply (TP507) originates from the
+10 V reference and the +12 V supply.
1. Unplug the signal generator and turn it upside-down.
2. Expose the motherboard by removing the bottom cover. It is secured by 15 screws.
3. Plug in the signal generator.
4. Measure the voltage of each supply to verify they are within the tolerances listed in
Table 1-3. The voltage supply test point locations are shown in Figure 1-4. If all the
voltages are within tolerance, proceed to “Step 7: Check for Basic CPU Functionality”.

h. AT1 Electronic Attenuator/RPP - disconnect W13
AT1 Mechanical Attenuator and A19 RPP (Option UNB) - disconnect W13 and
A19W1
i. A25 Pulse Modulator (Option 1E6) - disconnect A25W1
j. B1 Fan - disconnect B1W1 (disconnect only temporarily)
k. B2 Fan - disconnect B2W1 (disconnect only temporarily)
l. A9 Output Board
m. A11 Reference Board
n. A23 Sampler Board
o. A24 Frac-N/Divider Board
p. A22 YIG Driver Assembly - disconnect W35
NOTE
Refer to Chapter 4, “Replaceable Parts (ESG-AP and ESG-DP Series),” for
information on locating assemblies. Refer to Chapter 5, “Assembly
Replacement,” for information on removing or disconnecting assemblies.
3. Switch on the signal generator and check the voltage supply LEDs (see Figure 1-3). If
the LEDs are lit, you have likely identified the failed assembly. If one or more LEDs are
still off, switch off the signal generator and replace/reconnect the assembly and repeat
this procedure.

Service Guide
Step 7: Check for Basic CPU Functionality
The Digital Signal Processor (DSP) performs a self-diagnostic test at power up. If the DSP
is not working, the CPU reports an error.
If the DSP does not seem to be working and the CPU did not report the error, then check
the CLK_OUT signal at TP701. It should be a 16 MHz signal. (Refer to Figure 1-5.)
The eight LEDs of DS201 (see Figure 1-5) indicate the status of the boot and flash ROM for
the CPU. The LEDs form a binary code that can be described as a two digit hexadecimal
code. Table 1-4 shows the test sequence and the LED pattern (binary representation) of the
test that is running. If an error occurs and the test is halted, the LED pattern will indicate
which self test halted the process. The LED closest to R201 is the place holder for the Least
Significant Bit (LSB) in the pattern.

Additional Information for Troubleshooting the ESG-AP and ESG-DP Series
Additional Information for Troubleshooting the
ESG-AP and ESG-DP Series
Table 1-5 provides frequency-dependent settings for selected points in the RF signal flow of
the ESG-AP and ESG-DP Series Signal Generators. Notice that the settings are relative to
the RF output frequency. This information can improve your understanding of the signal
generator circuitry, especially when used with the RF block diagram.
The values for Table 1-5 assume FM modulation is turned off.

Troubleshooting with
Block Diagrams
This chapter provides the block diagrams and information necessary for you to test and
troubleshoot the major assemblies of your signal generator.
Service Guide
2-1
Assembly-Level Troubleshooting with Block Diagrams
troubleshooting your signal generator.
Using this Chapter with Service Software
Some block diagrams in this chapter are accompanied by a table for use with the
automated service software that came with your signal generator. These tables list the
signal generator’s test conditions and the expected ABUS node voltages. The service
software has a utility program which measures and displays the node voltages for each
test. Refer to your signal generator’s calibration guide for information on using the
software.
The block diagrams and ABUS node tables are arranged in the following order:

The node voltages given in the following table are approximate values based
on a sample of signal generators. Your signal generator may not reflect these
exact values. Additionally, the resolution of these values varies from node to
node. As a guideline, interpret your measurements based on the number of
decimal places shown for the expected voltage.

Save Money with Rebuilt-Exchange Assemblies
Under the rebuilt-exchange assembly program, certain factory-repaired and tested
assemblies are available on a trade-in basis. These assemblies cost less than a new
assembly, and meet all factory specifications required of a new assembly.
The defective assembly must be returned for credit under the terms of the
rebuilt-exchange assembly program. The figure below illustrates the assembly exchange
procedure in flowchart format.
Assembly Exchange Procedure
Service Guide
3-3
Shipping the Defective Assembly Back to Agilent Technologies
1. When you receive the rebuilt assembly, be careful not to damage the box in which it was
shipped. You will use that box to return the defective assembly. The box you receive
should contain the following:
• the rebuilt assembly
• an exchange assembly failure report
• a return address label
2. Complete the failure report.
3. Place the failure report and the defective assembly in the box. Be sure to remove the
enclosed return address label.
4. Seal the box with tape.
If you are inside the United States, stick the preprinted return address label over the
label that is already on the box and return the box to Agilent Technologies. (Agilent
Technologies pays postage on boxes mailed within the United States.)
If you are outside the USA, do not use the return address label; instead, address the box
to the nearest Agilent Technologies sales and service office. (Refer to Table 1-1 on
page 1-9.)

Figure 3-15 shows an ESG-D series front panel having options UN3/4 or UN8.
On a standard ESG-D series front panel, W3, W4, and W5 do not exist and
the front panel connectors for W1 and W2 will be in a slightly different
location. An ESG-A series front panel does not include W1 through W5, but
will include W47 with Option 1E6 (not shown). All models having
Option 1EM do not have W1 through W9 on the front panel.

Service Guide
Under the rebuilt-exchange assembly program, certain factory-repaired and tested
assemblies are available on a trade-in basis. These assemblies cost less than a new
assembly, and meet all factory specifications required of a new assembly.
The defective assembly must be returned for credit under the terms of the
rebuilt-exchange assembly program. The figure below illustrates the assembly exchange
procedure in flowchart format.
Assembly Exchange Procedure
Service Guide
4-3
Shipping the Defective Assembly Back to Agilent Technologies
1. When you receive the rebuilt assembly, be careful not to damage the box in which it was
shipped. You will use that box to return the defective assembly. The box you receive
should contain the following:
• the rebuilt assembly
• an exchange assembly failure report
• a return address label
2. Complete the failure report.
3. Place the failure report and the defective assembly in the box. Be sure to remove the
enclosed return address label.
4. Seal the box with tape.
If you are inside the United States, stick the preprinted return address label over the
label that is already on the box and return the box to Agilent Technologies.
(Agilent Technologies pays postage on boxes mailed within the United States.)
If you are outside the USA, do not use the return address label; instead, address the box
to the nearest Agilent Technologies sales and service office. (Refer to Table 1-1 on
page 1-9.)

The figure on the adjacent page represents an ESG-DP series front panel
having option UN8. On a standard ESG-DP series front panel, W3, W4, and
W5 do not exist and the front panel connectors for W1 and W2 will be in a
slightly different location. An ESG-AP series front panel does not include W1
through W5, but will include W47 with Option 1E6 (not shown). All models
having Option 1EM do not have W1 through W9 on the front panel.

General Safety Considerations
General Safety Considerations
The following safety notes apply specifically to ESG Family Signal Generators. These notes
also appear in other chapters of this service guide as required.
WARNING
These servicing instructions are for use by qualified personal only.
To avoid electrical shock, do not perform any servicing unless you
are qualified to do so.
WARNING
The opening of covers or removal of parts is likely to expose
dangerous voltages. Disconnect the product from all voltage sources
while it is being opened.
WARNING
The detachable power cord is the instrument disconnecting device.
It disconnects the mains circuits from the mains supply before other
parts of the instrument. The front panel switch is only a standby
switch and is not a LINE switch (disconnecting device).
WARNING
The power cord is connected to internal capacitors that may remain
live for 5 seconds after disconnecting the plug from its power supply.
WARNING
This is a Safety Class 1 Product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only
be inserted in a socket outlet provided with a protective earth
contact. Any interruption of the protective conductor inside or
outside of the product is likely to make the product dangerous.
Intentional interruption is prohibited.
WARNING
Danger of explosion if battery if incorrectly replaced. Replace only
with the same or equivalent type recommended. Discard used
batteries according to manufacturer’s instructions.
CAUTION
Many of the assemblies in this instrument are very susceptible to damage
from ESD (electrostatic discharge). Perform service procedures only at a
static-safe workstation and wear a grounding strap.
