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.

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.

:TRIGger[:SEQuence]:RFBurst:LEVel:ABSolute?
TRIG:RFB:LEV:ABS 10 dBm
sets the trigger level of the RF burst envelope signal to the absolute level of 10
dBm
Sending this command does not switch the setting from relative to absolute; to
switch it you need to send the :TRIGger[:SEQuence]:RFBurst:LEVel:TYPE
command, below.
Amplitude Corrections are not taken into account by the Absolute Trigger
Level. For example, if you have given yourself effective gain with an
amplitude correction factor, the Absolute Trigger will not fire until you have
set the trigger level that far below the displayed signal level, rather than
simply to the displayed signal level. This is only true for Amplitude
Corrections, not External Gain or Ref Level Offset functions.
If mode is Bluetooth, the default value is –50 dBm.
This same level is used for the RF Burst trigger source in the Trigger menu,
for the RF Burst selection in the Periodic Timer sync source (in the Trigger
menu and in the Gate Source menu), and also for the RF Burst selection in the
Gate Source menu
