4000 X-Series Oscilloscopes Service Guide 33
To verify DC vertical gain accuracy
This test verifies the accuracy of the analog channel DC
vertical gain for each channel.
In this test, you will measure the dc voltage output of an
oscilloscope calibrator using the oscilloscope’s
Average - Full Screen voltage measurement and compare the
results with the multimeter reading.

4000 X-Series ±2.0% of full scale • Full scale is defined as 32 mV on the 2 mV/div range
and the 1 mV/div range.
• Full scale on all other ranges is defined as 8 divisions
times the V/div setting.
