5 Perform these steps to test at the 5 mV/div setting:
a Set the signal generator amplitude to about 10 mV
pp
.
b Press the [AutoScale] key.
c Set the time base to 10 ns/div.
d Set channel 1 to 5 mV/div.
e Decrease the amplitude from the signal generator until 1 vertical division of
the signal (about 5 mV
pp
) is displayed.
The trigger is stable when the displayed waveform is stable. If the trigger is
not stable, try adjusting the trigger level. If adjusting the trigger level makes
the trigger stable, the test still passes. If adjusting the trigger does not help,
see the “Troubleshooting” chapter. Then return here.
f Record the result as Pass or Fail in the Performance Test Record (see
page 53).
g Repeat this step for the remaining oscilloscope channels.
6 Perform these steps to test at the 10 mV/div setting:
a Set the signal generator amplitude to about 20 mV
pp
.
b Press the [AutoScale] key.
c Set the time base to 10 ns/div.
d Set channel 1 to 10 mV/div.
e Decrease the amplitude from the signal generator until 0.6 vertical divisions
of the signal (about 6 mV
pp
) is displayed.
The trigger is stable when the displayed waveform is stable. If the trigger is
not stable, try adjusting the trigger level. If adjusting the trigger level makes
the trigger stable, the test still passes. If adjusting the trigger does not help,
see the “Troubleshooting” chapter. Then return here.
f Record the result as Pass or Fail in the Performance Test Record (see
page 53).
g Repeat this step for the remaining oscilloscope channels.
