6.21 TRIGger Subsystem
The TRIGger subsystem is used to synchronize instrument actions with events. It is thus possible to con-
trol and synchronize the start of a sweep. An external trigger signal can be applied to the connector at
the rear panel of the instrument. A distinction is made between TRIGger1 (screen A) and TRIGger2
(screen B).
TRIGger<1|2>[:SEQuence]:HOLDoff -100 to 100s
This command defines the length of the trigger delay.
A negative delay time (pretrigger) can be set in the time domain (span = 0 Hz) only.
Example:
"TRIG:HOLD 500us"
Characteristics: *RST value: 0 s
SCPI: conform
Mode: A
TRIGger<1|2>[:SEQuence]:HOLDoff:ADJust:AUTO ON|OFF
This command defines whether the group delay of the bandwidth filters for the external or IF power
trigger is compensated (ON) or not (OFF). If a burst signal is analyzed in the time domain mode, the
rising edge will remain at the same time position if compensation is on and the bandwidth changes.
Example:
"TRIG:HOLD:ADJ:AUTO ON"
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
TRIGger<1|2>[:SEQuence]:LEVel[:EXTernal] 0.5 to +3.5 V
This command sets the level of the external trigger source.
Example:
"TRIG:LEV 2V"
Characteristics: *RST value: 1.4 V
SCPI: device-specific
Mode: A
TRIGger<1|2>[:SEQuence]:LEVel:IFPower -30 to –10 dBm
This command sets the level of the IF power trigger source.
Example:
"TRIG:LEV:IFP –20DBM"
Characteristics: *RST value: -20 dBm
SCPI: device-specific
Mode: A
