• The trigger source setting is stored in volatile memory; the source is
set to internal trigger (front panel) or immediate (remote interface)
when power has been off or after a remote interface reset. (Provided
that the Power On state is set to Factory.)
• Front-Panel Operation: After enabling sweeps or bursts, press
and
select the desired source by pressing the Trg Src softkey.
• Remote Interface Operation:
TRIGger[1|2]:SOURce {IMMediate|EXTernal|TIMer|BUS}
The APPLy command automatically sets the source to Immediate.
Immediate Triggering
In the internal trigger mode, the waveform
generator
continuously outputs the sweep or burst (as specified by the
sweep time or burst period). This is the default trigger source for both
front-panel and remote interface use.
• Front-Panel Operation:Press
and then press Trg Src and
select Immed.
• Remote Interface Operation:
TRIGger:SOURce IMMediate
Manual Triggering In the manual trigger mode (front panel only),
you can manually trigger the waveform generator by pressing the front-
panel
key. The waveform generator initiates one sweep or outputs
one burst for each time you press the key. The
key is illuminated
when you are in the trigger menu and the waveform generator is waiting
for a manual trigger. The
key blinks when the waveform
generator is waiting for a manual trigger, but you are not in the trigger
menu. The
key is disabled when the instrument in remote.
