R&S ESR
[SENSe:]POWer:ACHannel:PRESet:RLEVel
This command adapts the reference level to the measured channel power and – if
required – switches on previously the adjacent channel power measurement. This
ensures that the signal path of the instrument is not overloaded. Since the measure-
ment bandwidth is significantly smaller than the signal bandwidth in channel power
measurements, the signal path can be overloaded although the trace is still signifi-
cantly below the reference level. If the measured channel power equals the reference
level, the signal path is not overloaded.
Subsequent commands have to be synchronized with *WAI, *OPC or *OPC? to the
end of the auto range process which would otherwise be aborted.
Example:
Manual operation:
TRACe<n>:DATA <Trace>, <Data> | <ResultType>
This command queries current trace data and measurement results.
If you use it as a setting command, it transfers trace data from an external source to
the R&S ESR.
The data format depends on FORMat[:DATA].
Parameters:
<Trace>
<Data>
Query parameters:
<ResultType>
Return values:
<TraceData>
