17 Press the [Default Setup] front panel key.
18 Set the channel’s probe attenuation to 1X.
19 Set the channel’s vertical sensitivity value to 2 mV/div.
20 Press [Measure].
21 Press the Voltage softkey.
22 Turn the entry knob to select the Vavg measurement.
23 For each of the channel’s vertical sensitivities in the DC Gain Test
section of the “Performance Test Record” on page 35:
a For the positive (+) power supply setting:
i Record the DMM voltage reading as VDMM+.
ii Record the oscilloscope Vavg reading as VScope+.
b For the negative (- ) power supply setting:
i Record the DMM voltage reading as VDMM-.
ii Record the oscilloscope Vavg reading as VScope- .
c Calculate the DC Gain using the following expression and record this
value in the DC Gain Test section of the Performance Test Record:
