Decrease the output of the signal generator until there is 0.5 vertical
divisions of the signal displayed.
The trigger should be stable. If the triggering is not stable, try
adjusting the trigger level. If adjusting the trigger level makes the
triggering stable, the test still passes. If adjusting the trigger does not
help, see "Troubleshooting the Oscilloscope," on page 4-32.
Record the result on the Performance Test Record as Pass or Fail.
