Trigger Controls
1 Press [AutoScale] to return to a simple setup.
2 Set the time base to 50 ns/div.
3 Rotate the trigger level knob up and down. The trigger level is displayed
while it is adjusted.
If the trigger level is above or below the signal, the oscilloscope will force a
trigger and display a waveform when in Auto mode. Auto is a useful trigger
mode to use when unsure of the exact waveform, as activity will be
displayed making it easy to better configure the oscilloscope’s settings and
trigger level.
When triggers are forced, the white
Auto LED (in the Run Control section) is
lit. When the oscilloscope finds the trigger event, the white Trig’d LED is lit.
4 Press the [Sweep] key in the trigger section to toggle from Auto mode to
Trig’d mode.
5 Now, move the trigger level up and down.
The oscilloscope only triggers when a valid trigger condition exists. Use the
Trig’d mode when you want to set a specific trigger condition and capture
waveforms only when those conditions are met.
When waiting for trigger, only the white
Arm’d LED is lit. When the
oscilloscope finds the trigger event, the white Trig’d LED is also lit.
