[SENSe:]POWer:SEM:TRACe:REDuction <Method>
This command specifies how trace reduction is performed for the Spectrum Emission
Mask (SEM) measurement.
Parameters:
<Method> PEAK
For each frequency range, the peak detector is used to deter-
mine the corresponding trace value. This was the behaviour for
the SEM measurement in R&S FSV-K91 versions before 1.70.
DETector
For each frequency range, the trace detector defined in the SEM
xml file is used to determine the corresponding trace value.
*RST: PEAK
Example:
POW:SEM:TRAC:RED PEAK
Set SEM measurement to use peak trace reduction
Mode: WLAN
Manual operation: See "Trace Reduction" on page 82
[SENSe:]SWAPiq <State>
This command defines whether or not the recorded IQ pairs should be swapped (I<-
>Q) before being processed. Swapping I and Q inverts the sideband.
Parameters:
<State> ON | OFF
ON
I and Q are exchanged, inverted sideband, Q+j*I
OFF
Normal sideband, I+j*Q,
*RST: OFF
Example:
SWAP ON
Specifies that IQ values should be swapped.
Mode: WLAN, GSM, OFDM, OFDMA/WiBro
Manual operation: See "Swap IQ " on page 92
[SENSe:]SWEep:COUNt <NumberSweeps>
This command specifies the number of sweeps for Spectrum Mask and Spectrum
ACPR measurements.
Parameters:
<NumberSweeps> *RST: 1
Example:
SWEep:COUNt 64
Sets the number of sweeps to 64.
