DC Function Offset Verification
This test verifies the DC offset and DC output specifications.
Set the function generator for each output indicated in the table below.
Use a DMM to measure the function generator dcV output. Compare the
measured results to the test limits shown in the table. This is a HIGH Z
output termination test.

AC Amplitude Verification
This procedure is used to check the output amplitude calibration of the
function generator. Verification checks are performed to check the
accuracy of the pre-attenuator and post attenuator.
Make sure you have
read “Test Considerations” on page 53.
Set the function generator for each output indicated in the table on the
next page. Use a DMM to measure the ACrms output voltage of the
function generator. Compare the measured results to the test limits
shown in the table. This is a HIGH Z output termination test.
