[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:
POW:ACH:PRES:RLEV;*WAI
Adapts the reference level to the measured channel power.

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> Selects the trace to write data to.
TRACE1 | ... | TRACE6
<Data> Contains the data to transfer.
Query parameters:
<ResultType> Selects the type of result to be returned.
TRACE1 | ... | TRACE6
Returns the trace data for the corresponding trace.
LIST
Returns the results of the peak list evaluation for Spurious Emis-
sion and Spectrum Emission Mask measurements.
SPURious
Returns the peak list of Spurious Emission measurements.
Return values:
<TraceData> For more information see tables below.
Example:
TRAC TRACE1,+A$
Transfers trace data ('+A$') to trace 1.
Example:
TRAC? TRACE3
Queries the data of trace 3.
