Trigger
Trigger
Accesses a menu of keys to control the selection of the trigger source and the setup of each of the
trigger sources. The analyzer is designed to allow triggering from a number of different sources,
for example, Free Run, Video, External, RF Burst, and so forth.
The TRIG:SOURCe command (below) will specify the trigger source for the currently selected input
(RF or I/Q). If you change inputs, the new input remembers the trigger source it was last
programmed to for the current measurement, and uses that trigger source. You can directly set
the trigger source for each input using the TRIGger:RF:SOURce and TRIGger:IQ:SOURce commands
(later in this section). When in External Mixing, the analyzer uses the RF trigger source.
Note the inclusion of the <measurement> parameter in the command below. Because each
measurement remembers its own Trigger Source, the command must be qualified with the
measurement name. Note that for the Swept SA measurement this is not the case; for backwards
compatibility, no <measurement> parameter is used when setting the Trigger Source for the Swept
SA measurement.

Key Path Front-panel key
Remote Command :TRIGger:<measurement>[:SEQuence]:SOURce EXTernal1 | EXTernal2 |
IMMediate | LINE | FRAMe | RFBurst | VIDeo | IF | ALARm | LAN | IQMag |
IDEMod | QDEMod | IINPut | QINPut | AIQMag | TV
:TRIGger:<measurement>[:SEQuence]:SOURce?
where <measurement> is the measurement for which you wish to set the Source (blank for the
Swept SA measurement)
Example TRIG:ACP:SOUR EXT1
Selects the external 1 trigger input for the ACP measurement and the selected input
TRIG:SOUR VID
Selects video triggering for the Swept SA (SANalyzer) measurement in the Spectrum Analyzer
mode. For SAN, do not use the <measurement> keyword. Only send this form in the Spectrum
Analyzer mode or you will get an Undefined Header error
Notes Not all measurements have all the trigger sources available to them. Check the trigger source
documentation for your specific measurement to see what sources are available.
Not all trigger sources are available for each input. See the "RF Trigger Source" on page 1397
and "I/Q Trigger Source" on page 1398 commands for detailed information on which trigger
sources are available for each input.
