Look at the three ramps on the waveform monitor display. The larger of the
two ramps should each have 16 equal steps.
NOTE.
View the waveform display in full screen mode for easiest viewing.
10.
Use the Gain function on the waveform monitor to expand the signal to 10X.

Now check that the shallowest ramp has 16 equal steps.
12.
Record Pass or Fail in the test record.
13.
Check that the RAMP HPF calibration setting has not changed. If it has,
then restore the original value.
