Use these tests if you want to check that the Agilent 81133A / 81134A
Pulse / Pattern Generator is working correctly. Before starting any testing
allow all test equipment to warm up for at least 30 minutes and make
sure that the SELFCAL of the unit was executed.
Test Results Tables
Tables for entering the results of the tests are included at the end of the
tests. 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.

Important:
When you connect the test equipment for the first time, and whenever
you change the setup during the course of these tests, always switch off
the 81133A/81134A' s outputs.
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.
