CALCulate<1...2>:MARKer<1...6>:FUNCtion:LEVel:ONCE
This command adjusts the reference level to the measured signal power.
This automatic routine makes sure that the signal power level does not overload the
R&S Spectrum Rider or limits the dynamic range by too small an S/N ratio.
To determine the best reference level, the R&S Spectrum Rider aborts current mea-
surements and performs a series of test sweeps. After it has finished the test, it contin-
ues with the actual measurement.
This command is an event and therefore has no *RST value and no query.
The numeric suffix at CALCulate is irrelevant for this command. The numeric suffix at
MARKer selects the marker.
Example:
CALC:MARK:FUNC:LEV:ONCE
Initiates an automatic level adjust routine.
