Overview
Overview
Overview
The 8753ES Option H85 provides a built-in, high-power capable test
set. High power measurements can be made up to 20 watts (+43 dBm)
maximum at each test port. The usable frequency range of the
Option H85 is 50 MHz to 3 GHz or 6 GHz with the standard Option 006.
Frequencies below 50 MHz are degraded due to the roll-off of the
couplers.
The front panel test ports are 3.5mm male. All other front panel
connections are 3.5mm female.
The 8753ES Option H85 uses a mechanical transfer switch (A24) to
route the RF signal to Port 1 or Port 2. The inactive port is grounded
through the transfer switch. Continuous switching is not allowed
between forward and reverse measurement states.
Access to the analyzer’s RF source is located on the rear panel of the
analyzer. These connections are 3.5mm female. This allows an RF
amplifier to be connected in the RF source path to increase test port
power.
Test port coupler access to the transfer switch is located on the front
panel. Coupler access allows the user to connect high power circulators
or isolators to protect the internal transfer switch when making high
power measurements.
A and B channel access to the samplers is also located on the front
panel. Sampler access allows the user to increase the dynamic range
and lower the noise floor. The maximum power to the A and B samplers
is +10 dB. Recommended power to the sampler is –10 dB. Maximum
power to the attenuators is 1 watt (+30 dBm).
The A and B channel attenuators are built into the Option H85 test set.
The attenuators may be set with different settings. Once the values are
set, they must remain the same for both the forward and reverse
measurements. Once set, they cannot be uncoupled to allow a channel
attenuator forward measurement to differ from reverse measurement
state value settings.
These variable mechanical attenuators range from 0 to 55 dB in 5 dB
steps. The variable attenuators are used to reduce the power to the A
and B channel samplers. The A and B channel attenuators can either be
controlled manually by the 8753ES display user softkeys or by GPIB
settings. These settings can be saved in instrument states.
Do not exceed the maximum power of 10 dBm to the A, B, and R
Samplers. If the maximum power is exceeded, damage will occur.
Overview
3
Overview
The R IN port is located on the front panel and allows direct access to
the R–Channel. R IN is used to provide an external reference signal
used for ratioing. To ensure optimum power level at the receiver, add
any needed attenuation to reduce the power level to –10 dBm. R IN’s
external maximum power is +10 dBm.
The Option H85 default is set to the internal reference channel when
the instrument is preset or during power on.
Control of the internal reference switch is provided using the
TESTSET I/O FWD and TESTSET I/O REV display keys and GPIB
commands. A decimal value of seven is for internal and a decimal value
of six is for external.
Analyzers equipped with Option H85 can be configured to measure high
power devices. This ability is useful if the required input power for a
device under test is greater than the analyzer can provide, or if the
maximum output power from an amplifier under test exceeds the safe
input limits for a standard analyzer.
Analyzers equipped with Option H85 are capable of increasing their RF
output levels by means of inserting an external, high power booster
amplifier. As a result, up to 20 watts (+43 dBm) can be delivered to a
device or amplifier under test. The maximum test port input power is
1 watt (+30 dBm) CW, but jumpers on the front panel allow the
insertion of high power attenuators or isolators. This allows test device
output levels up to the power limits of the inserted components.

High Power Amplifier Testing
Analyzers equipped with Option H85 are capable of increasing their RF
output levels by means of inserting an external, high power booster
amplifier. As a result, up to 20 watts (+43 dBm) can be delivered to a
device under test (DUT) or amplifier under test. The maximum test
port input power is 1 watt (+30 dBm) CW, but jumpers on the front
panel allow the insertion of high power attenuators or isolators. This
allows test device output levels up to the power limits of the inserted
components.
To protect the analyzer from high power levels, this option allows the
addition of isolators at both test ports and includes internally controlled
step attenuators located between the couplers and samplers.
NOTE
When making high power amplifier measurements, careful planning is
required and precautions must be observed. For more information on
how to make high power measurements, refer to the chapter on
“Making Measurements” in the standard documentation.
Figure 2-1 provides the test configuration for setting up the RF Input
using automatic power meter calibration.

Chapter 2
High Power Measurements
Analyzers equipped with Option H85 can be configured to measure high
power devices. This ability is useful if the required input power for a
device under test is greater than the analyzer can provide or if the
maximum output power from an amplifier under test exceeds safe input
limits for a standard analyzer. The Option H85 can be set up in the
standard mode of operation. However, in the standard mode of
operation the Option H85 will not be able to make high power
measurements.

2. Determining Power Levels
3. Additional Setup

Initial Setup
Figure 2-2 shows the initial setup of the Option H85 for making high
power measurements.
1. If the analyzer is in the bypass mode configuration, remove the
jumper between the RF OUT and RF IN connector on the rear panel.
2. Connect the booster amplifier RF INPUT connector to the RF OUT
connector on the rear panel of the analyzer.
3. Connect a 20 dB coupler (that operates within the frequency range of
interest) to the booster amplifier RF OUTPUT connector.
Figure 2-2
High Power Test Setup

Chapter 2
Determining Power Levels
The following provides the information needed to determine what the
correct power levels are and what additional attenuation is needed, if
any.
4. Switch on the analyzer and reduce the power level to −20 dBm by
pressing Menu, POWER, PWR RANGE AUTO, POWER RANGES, −20 x1.
5. Switch on the booster amplifier.
6. Using a power meter, measure the output power from the coupled
arm and the open port of the coupler.
NOTE
Depending on the power meter being used, additional attenuation may
need to be added between the coupler port and the power meter.
7. Verify the gain of the booster amplifier. For example, if the analyzer
output power level was set to −20 dBm and the output power
measured from the open end of the coupler was −5 dBm, then the
gain of the booster amplifier would be +15 dB.
8. Verify that the power measured in step 6 is well within the
acceptable limits (less than −10 dBm for the coupled arm, less than
+43 dBm for the open port).
9. Estimate the maximum power level that will be needed to force the
DUT into compression.
10.At the maximum estimated power level, determine if the maximum
output power from the coupled arm of the coupler will be higher than
the acceptable limit. If so, add the appropriate amount of
attenuation that will keep the coupled output power below 0 dBm
and above −25 dBm.
Chapter 2
2-5
Additional Setup
Figure 2-3 (rear view) and Figure 2-4 (front view) show how to make the
RF amplifier and coupler connections to the Option H85.
11.Switch off the booster amplifier.
12.Make a connection between the open port of the 20 dB coupler and
the RF IN connector on the rear panel of the analyzer.
13.Make a connection between the coupled arm of the 20 dB coupler
(along with any added attenuation) and the R-CHANNEL IN
connector on the front panel.
14.Turn the Phase Lock OFF. Press System, SERVICE MENU, SERVICE
MODES, PLL AUTO OFF.

Chapter 2
Selecting Power Ranges and Attenuator Settings
The following information describes how to select the correct power
range, if an isolator is needed, and what amount of attenuation is
needed. Refer to Figure 2-5 to identify the internal signal paths of the
analyzer.
15.Select a power range that will not exceed the maximum estimated
power level that will force the DUT into compression. For example, if
your booster amplifier has a gain of +15 dB and the DUT will
compress if supplied with +20 dBm, then you would adjust the
analyzer output power to not exceed +5 dBm by pressing Power,
PWR RANGE MAN, POWER RANGES, RANGE 0 −15 TO +10.
16.Adjust the analyzer power level to be below the maximum limit of
the power range by pressing 0 (or less) x1.
17.Estimate the maximum amount of gain that could be provided by the
DUT and, as a result, the maximum amount of power that could be
received by TEST PORT 2 when the DUT is in compression. For
example, if a DUT with a maximum gain of +10 dB receives an input
of +20 dBm, then the maximum amount of power that could be
received by TEST PORT 2 is +30 dBm. If this power level is greater
than +30 dBm, an isolator is needed to protect the internal
mechanical transfer switch.
Figure 2-5
Internal Signal Paths of Analyzer
Chapter 2
2-7
18.Calculate the amount of attenuation needed between the analyzer's
couplers and samplers in order to not exceed the optimum sampler
power level of −10 dBm.
In this example, it will be necessary to take the following into
consideration:
• Sampler A will be coupled to the analyzer RF path that could
receive power reflections as high as +20 dBm.
• Sampler B will be coupled to the analyzer RF path that will
receive a maximum of +30 dBm from the DUT.
• Analyzer coupler loss is −16 dB.
• The optimum sampler power level is −10 dBm.
With the above points in mind, the amount of attenuation can be
calculated from the following equations:
• Attenuator A = +20 dBm − 16 dB − (−10 dBm).
Attenuator A = −14 dB
• Attenuator B = +30 dBm − 16 dB − (−10 dBm).
Attenuator B = −24 dB
19.Set the internal step attenuators to the values calculated in the
previous step (rounding off to the highest 5 dB step). Press System,
CONFIGURE MENU, OPTION HXX CONFIG, ATTENUATOR A, 15 x1
ATTENUATOR B 25 x1.
20.Switch on the booster amplifier.
CAUTION
From this point forward, DO NOT press Preset unless you have first
switched off the booster amplifier. Pressing Preset will return the
analyzer to its default power level and default internal attenuator
settings. This increase in power may result in damage to the DUT or
the analyzer.
21.To activate the external reference mode, press Seq, TTL IO, TTL OUT,
TESTSETIO, 6 x1, I/O REV, 6 x1.
22.Measure the output power from TEST PORT 1 and verify that it is
as expected.
23.If you are measuring a highly reflective device, high power isolators
should be inserted in place of the jumpers located between the two
sets of front panel SWITCH and COUPLER connectors.
2-8
Chapter 2
Final Setup
The following steps provide the information needed to set measurement
parameters and what considerations need to be taken for interpreting
the measured data.
24.Confirm that all power and attenuator settings are correct and set
the following measurement parameters:
Meas, Trans: FWD S21 (B/R)
25.Perform a response calibration:
• Connect the test port cables of the analyzer to form a thru
configuration.
• Press Cal, CALIBRATE MENU, RESPONSE, THRU.
26.Make the connections shown in Figure 2-6. Switch on the AUT
(amplifier under test) and measure the S21 gain of the amplifier
under test to confirm the proper operation of the measurement test
set up.
Figure 2-6
High Power Test Setup
27.Make any other desired high power measurements.
Ratio measurements such as gain will be correctly displayed.
However, the displayed absolute power levels on the analyzer will
not be correct. To correctly interpret power levels, the gain of the
booster amplifier and the attenuator settings must be taken into
consideration.
Chapter 2
2-9
NOTE
If you are increasing the power level from the level set at calibration to
the maximum level of compression, you must press Cal, INTERPOL ON to
switch on interpolation.
If no calibration has been performed or if the instrument is in an
uncalibrated state, the following must be taken into consideration when
interpreting the measured data:
• The value of attenuation added to sampler A and B.
• The R-Channel reference level supplied from the coupled arm of the
20 dB coupler.
