DC Function Offset Verification

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.

1Output termination set using front panel controls. HIGH Z assumes no load on output. 50W assumes a 50W 0.1Wload on output.
