Agilent 81110A/'11A Performance Test
Introduction
Use the tests in this chapter if you want to check that the Agilent
81110A Pulse Generator Frame with the Agilent 81111A 165
MHz Output Channel(s) is working correctly. Before starting any
testing allow all test equipment to warm up for at least 30 minutes.
Conventions Used
When referring to actions that you perform during the tests, the
following conventions are used:
FUNCTION This indicates that a labelled button must be pressed
[MODE/TRG] This shows that a soft-key must be pressed. A soft-
key is an unlabelled button whose label is shown on the display,
and which can vary according to the job that the button is doing
CONTINUOUS PULSES This is an option shown on the dis-
play, and is selected by use of the vernier keys. It is shown in
upper or lower case to match the case displayed.
Test Results Tables
Tables for entering the results of the tests are included at the end
of this chapter. The tests are numbered and reference numbers for
each Test Result (TR) are given in a small table at the end of each
test. The reference number shows you where the actual results
should be entered in the Test Results Tables.
The Test Results tables at the end of the chapter should be photo-
copied, and the Test Results entered on the copies. Then, if the
tests need to be repeated, the tables can be copied again.

If Channel 2 has been fitted to your instrument, make an extra
copy of the Test Results tables for entry of the results of tests on
that channel. In this case, however, it is not necessary to repeat the
Period tests, as these are common to both channels.

NOTE: When you connect the test equipment for the first time, and
whenever you change the setup during the course of these tests,
use the 8710 - 1582 torque wrench to tighten and loosen SMA
connectors. This will ensure that the connectors are at the correct
tightness and give the best signal transfer.

Getting Started
The Agilent 81110A is controlled by selecting options in a series
of pages that are displayed on the instrument's screen. These
options vary with the boards that are fitted in the instrument.
When the Agilent 81110A is being tested, therefore, different situ-
ations can arise, depending on whether you have a standard instru-
ment or one that has had additional boards fitted. The following
examples illustrate this
