Trigger
Other trigger-related commands are found in the INITiate and ABORt SCPI command
subsystems.
*OPC should be used after requesting data. This will hold off any subsequent changes to the
selected trigger source, until after the sweep is completed and the data is returned.
Available ranges and presets can vary from mode to mode.
Dependencies In some models, there is no second External input. In these models, the External 2 key is
blanked and the EXTernal2 parameter will generate a “Hardware missing; Not available for this
model number” message.
Preset See table below
Status Bits/OPC
dependencies The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping
or Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger
event occurs and all the applicable trigger criteria have been met). A corresponding pop-up
message ("Waiting for trigger") is generated if no trigger signal appears after approximately 2
sec. This message goes away when a trigger signal appears.

Compatibility SCPI :TRIGger[:SEQuence]:SOURCe EXTernal
For backward compatibility, the parameter EXTernal is mapped to EXTernal1
Backwards
Compatibility SCPI [:SENSe]:<measurement>:TRIGger:SOURce
This backwards compatibility alias command is provided for ESA/PSA compatibility
This backwards compatibility command does not apply to the Swept SA measurement, for that
just use :TRIGger:SOURCe
This backwards compatibility command does not apply to the monitor spectrum, log plot and spot
frequency measurements
Backwards
Compatibility SCPI [:SENSe]:<measurement>:TRIGger:SOURce IF
In earlier instruments, the parameter IF was used by apps for the video trigger, so using the IF
parameter selects VIDeo triggering. Sending IF in the command causes VID to be returned to a
query.
Backwards
Compatibility SCPI [:SENSe]:ACPR:TRIGger:SOURce
This backwards Compatibility SCPI command is provided to support the same functionality as
[:SENSe]:ACPr:TRIGger:SOURce (PSA W-CDMA, PSA cdma2000 and PSA 1xEVDO) due to the
fact that the ACPr node conflicts with the ACPower node.
