Trigger Source Choices
Applies only to burst and sweep
. You must specify the source from which
the function generator will accept a trigger.
•
From the
front panel
, the function generator will accept a single
trigger, a hardware trigger from the
Ext Trig
terminal, or
continuously output bursts or sweeps using the internal trigger.
At power-on, internal trigger is selected.
•
From the
remote interface
, the function generator will accept
a software (bus) trigger, a hardware trigger from the
Ext Trig
terminal, or an immediate internal trigger.
•
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.
•
To select the trigger source from the remote interface, use the
following command. The
APPLy
command automatically sets the
trigger source to
IMMediate
.
TRIGger:SOURce {IMMediate|EXTernal|BUS}
Internal Triggering
In this trigger mode, the function generator
continuously outputs the burst or sweep (as specified by the
burst rate
or
sweep time
). This is the power-on trigger source for both front-panel
and remote interface use.
To select the internal trigger source from the remote interface, use the
following command. The
APPLy
command automatically sets the
trigger source to
IMMediate
.
"TRIGGER:SOURCE IMMEDIATE"
