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 50ĂW coaxial cable, a BNCĆtoĆdual banana adapter, and a
digital multimeter (DMM).
Prerequisites The AWG2021 meets the prerequisites listed on page CĆ5.
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).
