Triggering on Waveforms
When Free Run is selected, the test tool updates the
screen even if there are no triggers. A trace always
appears on the screen.
When On Trigger is selected, the test tool needs a trigger
to display a waveform. Use this mode if you want to
update the screen only when valid triggers occur.
When Single Shot is selected, the test tool waits for a
trigger. After receiving a trigger, the waveform is displayed
and the instrument is set to HOLD.
In most cases it is advised to use the Free Run mode:
4 Select Free Run, jump to Trigger
Filter.
ENTER
5 Set Trigger Filter to Off.
