softkey.
2
Connect the signal generator to channel 1.
3
Verify the trigger sensitivity at 25 MHz and 0.35 divisions.
a
Set the signal generator to 25 MHz and about 50 mV.
b
Press
Autoscale
.
c
Decrease the output of the signal generator until there is 0.35 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 4–40.
4
Verify the trigger sensitivity at 1 division for the frequencies shown
below.
a
Change the output of the signal generator to the frequency shown
below for your instrument and set amplitude to about 100 mV.
