8 Trigger
8.1 Trigger
For the Level trigger source, used in RTSA and other measurements, External Gain
and Ref Level Offset modify the actual trace data as it is taken and are taken into
account by Trig Level.
Remote Command
:TRIGger[:SEQuence]:<trig_source>:LEVel <ampl>
:TRIGger[:SEQuence]:<trig_source>:LEVel?
where <trig_source> is one of:
EXTernal1 | EXTernal2 | EXTernal3 | VIDeo | ADC | LEVel | IQMag | IDEMod |
QDEMod | IINPut | QINPut | AIQMag | INTernal
Example
:TRIG:VID:LEV -40 dBm
Dependencies Only appears when Video, External 1|2, or an I/Q trigger is selected as the Trigger Source
State Saved Saved in instrument state
Backwards
Compatibility SCPI
:TRIGger[:SEQuence]:IF:LEVel
taken as video trigger level
:TRIGger[:SEQuence]:IF:LEVel?
taken as video trigger level query
:TRIGger[:SEQuence]:EXTernal:LEVel
the parameter EXTernal is mapped to EXTernal1
:TRIGger[:SEQuence]:FRAMe:EXTernal1:LEVel
8.1.3 Trigger Delay
Controls a time delay that the instrument will wait to begin a sweep after meeting
the trigger criteria, for Trigger and Gate sources that support Trigger Delay.
For any given Trigger, Gate, or Periodic Sync source, the same Trigger Delay is used
for the Trigger source in the Trigger menu, for the Gate source in the Gate Source
menu, and for the Periodic Sync source in the Periodic Sync Src menu.
Negative trigger delays can be used. Negative trigger delay makes intuitive sense in
time domain and works well in FFT mode where the bandwidth of the filter before
the video trigger is about 1.25 span. You can use negative delay to pre-trigger the
instrument in the time domain or FFT, but not in swept spans. Video trigger delay
may be set to negative values, in time domain, FFT and even swept, but in swept
spans, negative settings of Trig Delay are treated as a zero setting within the internal
hardware and the advisory message "Neg. Trig Delay unavailable in Swept Mode,
zero delay used." is generated when such a delay is set.
Remote Command
:TRIGger[:SEQuence]:<trig_source>:DELay <time>
:TRIGger[:SEQuence]:<trig_source>:DELay?
where <trig_source> is one of:
LINE | EXTernal1 | EXTernal2 | EXTernal3 | AEXTernal | VIDeo | ADC | RFBurst | FRAMe | LEVel | FMT |
