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
Source" on page 572 and "I/Q Trigger Source" on page 573
detailed information on which trigger sources are available for each input.
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.
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.
See table below
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.
[:SENSe]:<measurement>:TRIGger:SOURce
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 at all.
The backwards Compatibility SCPI command,
[:SENSe]:ACPR:TRIGger:SOURce, 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.
In earlier instruments, the parameter IF was used by apps for the video trigger,
so using the IF enum selects video triggering.
Sending IF in the command causes VID to be returned to a query.
