Trigger

  • Trigger Source has three choices:
  1. External1

  3. Free Run
  • SCPI Reference
#:TRIGger:<meas>[:SEQuence]:SOURce
#EXTernal1|EXTernal2|IMMediate|LINE|FRAMe|RFBurst|VIDeo|IF|ALARm|LAN|IQMag|
#IDEMod|QDEMod|IINPut|QINPut|AIQMag|TV

#In PXA, the trigger source setting is local for each measurement. Include the <meas> keyword #in the command to specify
#the measurement for which you wish to set the trigger source. If the <meas> keyword is omitted (as for the PSA
#command), the setting applies only to the Swept SA measurement.
#PXA supports the command :TRIGger[:SEQuence]:SOURCe EXTernal for backwards compatibility. In this case, the
#parameter EXTernal is mapped to EXTernal1.
#The PSA command [:SENSe]:<meas>:TRIGger:SOURce is supported by PXA for backwards compatibility, but not for
#the Swept SA, Monitor Spectrum, Log Plot or Spot Frequency measurements. If you specify the IF option with this command, PXA selects VIDeo triggering.
#PXA also supports the backwards compatibility command [:SENSe]:ACPR:TRIGger:SOURce, which is mapped to [:SENSe]:ACPr:TRIGger:SOURce for PSA's W-CDMA, cdma2000 and 1xEVDO modes.
