Verifying Oscilloscope Performance
To verify Vertical Output on Option 005
In this test we will use the oscilloscope's channel 2 to measure the amplitude
of the Vertical Output (

Set channel 2
Measure the peak-to-peak amplitude of channel 2. It should be
7
greater than or equal to 63.6 mVp-p.
Because the measurement is being made at the full bandwidth of the
oscilloscope's channel, the peak-to-peak measurement is corrected for the
oscilloscope's high frequency roll off.
