Appendix D
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 165.

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.
