DC Output Verification
This test checks if the DC offset listed in the table below are within the spec
range using a DMM.
1. Set the DMM to measure DC voltage. Connect the DMM to the CH1 output
of the generator as shown below.
2. Turn on CH1 and select the DC waveform.
3. Set the instrument to each output value described in the table below and
measure the output voltage with the DMM. Be sure the generator output load
is set to High–Z and the output is enabled.
