Gain and Offset Accuracy Checks
Check Gain Accuracy
AWG2021 User Manual
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
Prerequisites
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).
