:TRIGger<1|2>[:SEQuence]:LEVel[:EXTernal] –5.0 to +5.0V
This command sets the level of the external trigger source.
Example:
":TRIG:LEV 2V"
Features: *RST value: –5.0V
SCPI: conforming
Modes: A, VA, BTS, MS
:TRIGger<1|2>[:SEQuence]:LEVel:VIDeo 0 to 100PCT
This command sets the level of the video trigger source.
Example:
":TRIG:LEV:VID 50PCT"
Features: *RST value: 50 PCT
SCPI: device-specific
Modes: A, VA, BTS, MS
:TRIGger<1|2>[:SEQuence]:LEVel:AF <numeric_value>
This command defines the level of the demodulated trigger source.
The ranges are:
AM-Demod
-120 to +120 PCT
FM-Demod -1kHz to +1 kHz
PM-Demod -12 .to.. +12 RAD
Example:
":TRIG:LEV:AF 50PCT"
Features: *RST value: 0 PCT
SCPI: device specific
Mode: VA-A
:TRIGger<1|2>[:SEQuence]:HOLDoff -100s to 100s
This command defines the length of the trigger delay.
Example:
":TRIG:HOLD 500us"
Features: *RST value: 0s
SCPI: conforming
Modes: A, VA
A negative delay time (pretrigger) can be set in the time domain (SPAN < 0 Hz) only. The maximum
permissible range and the maximum effective resolution of the pretrigger are limited by the set
sweep time (max range= - 499/500 x sweep time; max. resolution = sweep time/500). Pretriggering
is not possible when the rms or the average detector is activated.
