[SENSe:]POWer:ACHannel:PRESet <Measurement>
This command determines the ideal span, bandwidths and detector for the current
power measurement.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.

[SENSe:]POWer:ACHannel:PRESet:RLEVel
This command determines the ideal reference level for the current measurement.
This automatic routine makes sure that the that the signal power level does not over-
load the R&S
FPL1000 or limit the dynamic range by too small a S/N ratio.
To determine the best reference level, the R&S FPL1000 aborts current measurements
and performs a series of test sweeps. After it has finished the test, it continues with the
actual measurement.
To get a valid result, you have to perform a complete sweep with synchronization to
the sweep end. This is only possible in single sweep mode.
Usage: Event
[SENSe:]POWer:TRACe <TraceNumber>
This command selects the trace channel power measurements are performed on.
For the measurement to work, the corresponding trace has to be active.
