Function Gain and Linearity Verification
This test verifies the output amplitude accuracy specification for
sine wave, triangle wave, ramp, and square wave outputs.
sine wave, triangle wave, ramp, and square wave outputs.
Set the function generator for each output indicated in the table below. Use
a DMM to measure the function generator ACrms output voltage. Compare
the measured results to the test limits shown in the table. This is a HIGH Z
output termination test.

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.
