While TRIG:SOUR IMM provides the fastest trigger repetition rate, the trigger
occurrence time is not deterministic. In addition, there is no means to synchronize
the start of algorithm execution with an external input since when TRIG:SOUR is
IMM, ARM:SOUR must also be set to IMM. The TRIG:SOUR TIMER provides
both a deterministic occurrence of algorithm executions and the ability to
synchronize this with an external signal (ARM:SOUR EXT).

TRIGger:SOURce?
TRIGger:SOURce? returns the current trigger source configuration.

Returned Value: Discrete; one of BUS, EXT, HOLD, IMM, SCP, TIM or
TTLT0 through TTLT7. The C-SCPI type is string. See the TRIG:SOUR
command for more response data information.
Usage TRIG:SOUR? ask VT1419A to return trigger source
configuration
TRIGger:TIMer[:PERiod]
TRIGger:TIMer[:PERiod] <trig_interval> sets the interval between scan triggers.

Comments
·
In order for the TRIG:TIMER to start it must be Armed. For information on timer
arming see the ARM subsystem in this command reference.
·
The default interval is 10E-3 seconds. <interval> may be specified in seconds,
milliseconds (ms) or microseconds (us). For example; 0.0016, 1.6 ms, or 1600 µs.
The resolution for <interval> is 100 µs.
·
When Accepted: Before INIT only.
