TRIGger Subsystem

Language Reference

TRIGger Subsystem

The TRIGger subsystem is used to set the controls and parameters associated with triggering the data acquisitions. Other trigger-related commands are found in the INITiate and ABORt subsystems.

External Trigger, Line Trigger Delay Value

:TRIGger[:SEQuence]:DELay <delay>

:TRIGger[:SEQuence]:DELay?

This command sets the amount of trigger delay when using the rear panel external trigger input or the line trigger.

Factory Preset	1 ∝s
and *RST:	1 ∝s
Range:	0.3 ∝s to 429 seconds
Default Unit:	seconds

External Trigger, Line Trigger Delay Enable

:TRIGger[:SEQuence]:DELay:STATe OFFON01

:TRIGger[:SEQuence]:DELay:STATe?

This command allows you to turn on or off a delay, during which the analyzer will wait to begin a sweep after receiving an external trigger signal or a line trigger.

Factory Preset
and *RST:	Off
Default Unit:	seconds
Remarks:	Free-run activates the trigger condition that allows the next
	sweep to start as soon as possible after the last sweep. This
	function is not available when Gate is on.
Front Panel
Access:	Trig, Trig Delay On Off

External Trigger Slope

:TRIGger[:SEQuence]:EXTernal[1]:SLOPe POSitiveNEGative

:TRIGger[:SEQuence]:EXTernal[1]:SLOPe?

This command activates the trigger condition that allows the next sweep to start when the external voltage (connected to GATE TRIG/EXT TRIG IN on the rear panel) passes through approximately 1.5 volts. The external trigger signal must be a 0 V to +5 V TTL signal. This function only controls the trigger polarity (for positive or negative-going signals).
