[:SOURce]:PULM:INTernal:TRAin:TRIGger?
This command sets the triggering mode for the Pulse Train feature.

:PULM:INTernal:TRAin:TRIGger:IMMediate

[:SOURce]:PULM:INTernal:TRAin:TRIGger:IMMediate
[:SOURce]:PULM:INTernal:TRAin:TRIGger:IMMediate?
This command will cause the pulse train to run once. If the pulse train is
already running or off, then this SCPI command has no effect.

FRUN Free Run triggering continuously plays the pulse train.
TRIGgered Trigger runs the pulse train (after waiting the Pulse
Delay) each time an external trigger is supplied (edge
triggered) to the PULSE BNC, the "Trigger Immediately"
softkey is pressed, or the
[:SOURce]:PULM:INTernal:TRAin:TRIGger:IMMediate
SCPI command is sent (when the pulse train playback is
idle). Triggers received during playback are lost.
GATEd Gated triggering runs the pulse train while an external
trigger is supplied (level triggered) to the PULSE BNC.
The state of the GATEd trigger is detected only when
the playback is transitioning to or in idle. This means
that, once started, playback is always completed, even
if the GATE trigger changes to the inactive state.
