19 Select Default Setup in the Save/Recall menu.
20 Set the channel 2 vertical sensitivity value to 2 mV/div.
21 Press Measure
.
22 Select the Voltage menu item.
23 Select the Vavg measurement.
24 For each channel 2 vertical sensitivity in the DC Gain Test section of
the “Performance Test Record” on page 144:
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:

CAUTION
Ensure that the input voltage to the oscilloscope never exceeds 300 Vrms.
NOTE
This procedure is the only acceptable method for testing the bandwidth of a 3000 Series
oscilloscope.
