:TRIGger Subsystem
This subsystem contains commands related to the triggering of instrument functions for the purposes of synchronization. Related commands appear in the ABORt and INITiate subsystems.
:TRIGger[:SEQuence]:SOURce IMMediate|EXTernal|VIDeo
:TRIGger[:SEQuence]:SOURce?
Title
Trigger Source
Description
This command defines the trigger source. IMMediate triggering is the equivalent of free-run triggering. EXTernal triggering is triggered when a TTL signal is applied to the External Trigger input connector. EXTernal triggering is always done on the rising edge of the signal. It is available only in zero span mode.

Title
Video Trigger Position (Time)
Description
This command sets the video triggering delay as either a percentage of the display or in time units. If setting the delay by time is desired, then time units must be specified when sending the command. The query version of this command returns the video triggering delay as a percentage.
Parameter
<percentage> or <time>
Default Value
–1
Default Unit
%
Range
