[SENSe:]MSRA:CAPTure:OFFSet <Offset>
This setting is only available for slave applications in MSRA mode, not for the MSRA
Master. It has a similar effect as the trigger offset in other measurements.
Parameters:
<Offset> This parameter defines the time offset between the capture buf-
fer start and the start of the extracted slave application data. The
offset must be a positive value, as the slave application can only
analyze data that is contained in the capture buffer.
Range: 0 to <Record length>
*RST: 0
Default unit: S
Manual operation: See " Capture Offset " on page 63
[SENSe:]SWAPiq <State>
This command defines whether or not the recorded I/Q pairs should be swapped (I<-
>Q) before being processed. Swapping I and Q inverts the sideband.
This is useful if the DUT interchanged the I and Q parts of the signal; then the
R&S FSWP can do the same to compensate for it.
Parameters:
<State> ON | 1
I and Q signals are interchanged
Inverted sideband, Q+j*I
OFF | 0
I and Q signals are not interchanged
Normal sideband, I+j*Q
*RST: 0
Manual operation: See " Swap I/Q " on page 61
TRACe:IQ:BWIDth
This command defines or queries the bandwidth of the resampling filter.
The bandwidth of the resampling filter depends on the sample rate.
Parameters:
<Bandwidth> For details on the maximum bandwidth see Chapter 4.1.1,
"Sample Rate and Maximum Usable I/Q Bandwidth for RF
Input", on page 21.
Default unit: HZ
Manual operation: See " Analysis Bandwidth " on page 59
TRACe:IQ:RLENgth <NoOfSamples>
This command sets the record length for the acquired I/Q data.
