9. Perform steps 10 through 14, on both the instrument under test (to check the
Serial Input), and the second waveform monitor (to check the Serial Output
of the instrument under test).
10. Position the waveform so that you can check the ramps.
11. Check a major division of both ramps in the signals. Check for 11 to 13
even vertical steps over a major division (10 mV). The s teps should always
step upward in a m onotonic ramp. On the second waveform monitor, check
that there are no EDH errors (SD). If relevant, check that there are no CRC
errors (HD) by pressing and holding the STATUS button and selecting Video
Session.
