Spectrum Emission Results (Traces)
The following commands return the spectrum emission trace results of the multi evalu-
ation measurement.
FETCh:LTE:MEAS<i>:MEValuation:TRACe:SEMask:RBW<kHz>:CURRent?
FETCh:LTE:MEAS<i>:MEValuation:TRACe:SEMask:RBW<kHz>:AVERage?

Returns the values of the spectrum emission traces. Separate traces are available for
the individual resolution bandwidths (<kHz>). The results of the current, average and
maximum traces can be retrieved.

Comma-separated list of power results
The value in the middle of the result array corresponds to the
center frequency.
The test point separation between two results depends on the
resolution bandwidth:
RBW30
: separation 15 kHz
RBW100
: separation 45 kHz
RBW1000
: separation 90 kHz
For
RBW100
and
RBW1000
, results are only available for fre-
quencies, for which limits using these RBW have been defined.
For other frequencies INV is returned.
Range:
-120 dBm to 55 dBm
