TRIG:WAVeform:SOUR IQM
Selects I/Q magnitude triggering for the IQ Waveform measurement and the
I/Q input
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. For the
Source, the following trigger sources are available:
— IMMediate - free run triggering
— EXTernal1 - triggers on an externally connected trigger source on the rear
panel
— EXTernal2 - triggers on an externally connected trigger source on the front
panel
— IQMag - triggers on the magnitude of the I/Q signal
— IDEMod - triggers on the I/Q signal's demodulated I voltage
— QDEMod - triggers on the I/Q signal's demodulated Q voltage
— IINPut - triggers on the I channel's ADC voltage
— QINPut - triggers on the Q channel's ADC voltage
— AIQMag - triggers on the magnitude of the auxiliary receiver channel I/Q
signal
*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, an from mode to mode.d presets can vary
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.
