8 Trigger
8.1 Trigger
After the acquisition, the measurement searches for the peak in the acquired
waveform and saves it
2.
In the next cycle of the measurement, the measurement determines a new
absolute RF Burst level based on the peak value from the first measurement and
the Relative RF Burst Trigger Level (always 0 or negative dB) set by the user. The
following formula is used: absolute RF Burst level = peak level of the previous
acquisition + relative RF Burst level
3.
If the new absolute RF Burst level differs from the previous by more than 0.5 dB,
the new level is sent to the hardware; otherwise, it is not updated (to avoid
slowing down the acquisition)
Steps 2 and 3 repeat for subsequent measurements.
Remote Command
:TRIGger[:SEQuence]:RFBurst:LEVel:RELative <rel_ampl>
:TRIGger[:SEQuence]:RFBurst:LEVel:RELative?
Example Set the trigger level of the RF burst envelope signal to the relative level of -10dB:
:TRIG:RFB:LEV:REL -10 dB
Notes Sending this command does not switch the setting from absolute to relative; to switch it you need to
send :TRIGger[:SEQuence]:RFBurst:LEVel:TYPE
The relative trigger level is not available in some measurements. In those measurements the
RELative parameter, and :TRIGger[:SEQuence]:RFBurst:LEVel:TYPE generates an
error if sent
Dependencies This control is grayed-out and Absolute Trigger Level selected if the required hardware is not present
in your instrument and the current measurement does not support Relative triggering
Only appears when RF Burst is selected as the Trigger Source
Preset -6 dB

Compatibility SCPI
:TRIGger[:SEQuence]:RFBurst:LEVel
This legacy command is aliased to
:TRIGger[:SEQuence]:RFBurst:LEVel:RELative
because PSA had only relative burst triggering
In some models, a variety of burst trigger circuitry is available, resulting in various
available burst trigger bandwidths. The instrument automatically chooses the
appropriate trigger path based on the hardware configuration and other settings of
the instrument. Here is the RF Burst Trigger Bandwidth table for Swept SA
