1-2 Agilent 85110L Test Set
General Information
Introduction
Introduction
The purpose of this manual is to help you use the 85110L S-parameter test set effectively
and confidently. The 85110L is specially configured for operation in pulsed-RF
measurement systems. Four 70-dB step attenuators protect each input of the
fundamentally-mixed down-converter to allow measurement of test devices with output
power of 50 watts CW.
This manual may be inserted into the “Test Sets” section of the 8510C Test Set and
Accessories Manual.
The major topics of this chapter are:
• How to use the test set
• What the test set is
• Operating, safety, and warranty considerations
Verifying the Test Set
The 85110L has been designed to operate with 8510C network analyzers.
To install the instrument, refer to Chapter 2, “Installation.”
To check the proper operation of the test set, perform the system operational test as
described in the Operation section of 85108L System Manual. A successful calibration is an
indication that the system and the test set are both operating properly.
To see the specifications of the pulsed-RF network analyzer system with this test set, refer
to Specifications and Performance Verification section of the 85108L System Manual.
To verify that the instrument meets its published specifications, refer to the Performance
Tests section in the 85108L System Manual calibration.
To troubleshoot the testset, refer to Chapter 5, “Test Set Troubleshooting,” and the System
Service and Troubleshooting section of the 85108L System Manual. If unsuccessful,
contact the Agilent Technologies office nearest you.
Instruments Covered
A two-part serial number is located on the rear panel of the instrument. The first two
letters and first four digits are the serial number prefix. The last five digits are the
sequential suffix which is unique to each test set. The contents of this manual apply
directly to test sets with the same serial number prefix as the one(s) shown on the title
page.
If the serial prefix of your test set is not listed on the title page, your instrument differs
from those documented in this manual. The differences are documented in the manual
changes supplement supplied with the manual.

General Information
Introduction
Compatibility
The 85110L is compatible with 8510C network analyzers with firmware revision
8510C.06.50 and higher; and 8360-series synthesizers with firmware revision 8 MAR 91 or
later. If the network analyzer and source do not have the above revisions, it may be
necessary to upgrade the system to work with the 85110L. The 8510C must have
Option 008 in order to make pulse profile, pulsed-RF measurements.
Some 8510 systems may require later firmware revisions than those listed above. Please
consult the 8510C On-Site Service Manual and your Agilent representative for more
information on upgrading a network analyzer and source firmware (refer to “Contacting
Agilent” on page iv).
Characteristics
The 85110L uses two synthesizers to act as the RF and LO sources for the four mixer based
down-converter (Figure 1-1 on page 1-4). This approach eliminates the need to dedicate
one channel for phase-lock, making full two-port, pulsed-RF S-parameter measurements
possible.
Reflection measurements
The test set can handle up to 50 watts (47 dBm) because of the coupler-based measurement
path and attenuators. Remove the test set extension link for the appropriate port on the
rear panel of the test set and connect the LOW POWER OUT of the test set to the input of an
external amplifier. Then connect the output of that amplifier to the HIGH POWER IN on the
rear panel of the test set. This allows high power to be applied to the ports of the test set
without damage to the test sets switch splitter when making either S11 or S22 reflection
measurements. If 50 watts (47 dBm) is applied to port 1 via the HIGH POWER IN input on
the back of the test set, it will be necessary to add the same amount of attenuation to the
measurement path for port 1, to keep from over driving the a1 mixer and also to keep the
reflections from the port to the b1 mixer at a low level. The step attenuators for the a1 and
b1 mixers operate as a pair, as do the step attenuators for the a2 and b2 mixers.
Transmission measurements
If making either S12 or S21 measurements, where 50 watts (47 dBm) is applied to one of
the HIGH POWER IN inputs on the back of the test set. It will be necessary to apply 50 dB of
attenuation to all four step attenuators (both pairs). If an S21 measurement is being made,
it will be necessary to add either an isolation amplifier or the proper attenuation between
the port 1 or the port 2 link on the back of the test set (depending on which port is the
input). This will protect the switch splitter from damage by an input of more than
+17 dBm (see Figure 1-1).
85110L in a system
Combining the 85110L test set with the 8510C network analyzer with Option 008
(pulsed-RF measurement capability), an 83620B-H80 synthesizer with Options 001, 004,
008 for RF, an 83620B-H80 synthesizer with Options 004, 008 for LO, provide a system for
making pulsed-RF S-parameter measurements over the frequency range of 45 MHz to
2 GHz. Please contact your Agilent representative for more information on other

Introduction
compatible sources (refer to “Contacting Agilent” on page iv). This system is suited for
making pulsed-RF measurements on one or two port devices. It provides the ability to
measure and display the relative magnitude and phase shift of the device as a function of
time or frequency. It may also make measurements on two port devices when it is
inconvenient to physically reverse the DUT (device under test) to measure all four
S-parameters. This is especially important for non-reciprocal devices or components like
transistors, amplifiers or isolators where S12 measurements are important.

Precautions
Operating
CAUTION Beware of damage from electro-static discharge (ESD). The input connectors
(test ports or cables or adapters connected to the test ports) are very sensitive
to ESD. Use a grounded wrist strap when attaching devices to the input
connectors.
CAUTION During the retrace time of the network analyzer, the source power may
remain on.
Observe the following normal precautions in handling and operating the test set:
•Donot exceed the front-panel operating level power-input as shown in Table 1-3.
CAUTION To protect the switch splitter, any power in excess of +17 dBm into a port of
the 85110L must be offset by an equal or greater amount of attenuation. The
power into the test port must never exceed +47 dBm.
• Do not torque anything to the test port connector with greater than 136 Ncm (12 in-lb)
of torque. The wrench supplied with your accessory kit is calibrated to 12 in-lb.
• Do not torque any SMA connector on the back of the set with greater than 56 Ncm
(5 in-lb) of torque.
