Appendix C: Performance Verification

Gain and Offset Accuracy Checks

These procedures check the accuracy of the AWG2021 gain and offset.

NOTE. The gain and offset accuracy checks are structured as a continuous test. After Check Gain Accuracy, the next test uses the control settings from the last test and uses the next step in the sequence file.

Equipment Required

A 50)W coaxial cable, a BNC*to*dual banana adapter, and a

 

digital multimeter ￿DMM￿.

 

 

Prerequisites

The AWG2021 meets the prerequisites listed on page C*5.

 

 

1.Install test hookup and set controls:

a.Hook up DMM: Connect the AWG2021 CH1 output through a 50 W coaxial cable, a 50 W terminator and a dual banana connector to the DMM INPUT connector (see Figure C-15).
