1 Agilent 81133A/81134A Performance Verification Rev. 2.3, Dec Agilent Technologies

3 Introduction 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. 3

4 Recommended Test Equipment and Accessories The following tables list the recommended test equipment you need to perform all the tests. You can use alternative instruments if they meet the critical specifications given. The test setups and procedures assume you are using the recommended equipment.
