Agilent Technologies Signal Analyzer N9030a - Manual (Page 1426)

6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Trigger
RF Burst
Pressing this key, when it is not selected, selects the RF Burst as the trigger. A new
sweep/measurement will start when an RF burst envelope signal is identified from the signal at
the RF Input connector. Pressing this key, when it is already selected, accesses the RF Burst
trigger setup menu.
In some models, a variety of burst trigger circuitry is available, resulting in various available
burst trigger bandwidths. The analyzer automatically chooses the appropriate trigger path based
on the hardware configuration and other settings of the analyzer.

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.
Backwards Compatibility
Notes The legacy command:
:TRIGger[:SEQuence]:RFBurst:FSELectivity[:STATe] OFF|ON|0|1
is not supported in the X-Series, as the hardware to do Frequency Selective burst triggers does
not exist in X-Series.
Initial S/W Revision Prior to A.02.00
Modified at S/W
Revision A.04.00
Absolute Trigger Level
Sets the absolute trigger level for the RF burst envelope.
When using the External Mixing path, the Absolute Trigger Level is uncalibrated because the
factory default was set to accommodate the expected IF levels for the RF path.
