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.
Absolute Trigger Level
Sets the absolute trigger level for the RF burst envelope.
NOTE 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
Dependencies: No effect except in zero-span, but not locked out in nonzero spans.
Blanked in modes that do not support zero-span measurements. If the SCPI
command is sent when the key is blanked, an error is returned: –221,
“Settings conflict; Feature not supported for this measurement”
In analyzers shipping N9060A, this feature requires N9060A–7FP.

Example: TRIG:SOUR RFB Swept SA measurement

State Saved: Saved in instrument state
Status Bits/OPC 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.
