Sample Rate
Defines the I/Q data sample rate of the R&S FSWP. This value is dependent on the
defined Analysis Bandwidth and the defined signal source.
Note: The Spectrum Monitor is limited to a maximum sample rate of 25 MHz.
The following rule applies:
sample rate = analysis bandwidth / 0.8
For details on the dependencies see Chapter 4.1.1, "Sample Rate and Maximum Usa-
ble I/Q Bandwidth for RF Input", on page 21.
Remote command:
TRACe:IQ:SRATe on page 134
Analysis Bandwidth
Defines the flat, usable bandwidth of the final I/Q data. This value is dependent on the
defined Sample Rate and the defined signal source.
Note: The Spectrum Monitor is limited to a maximum analysis bandwidth of 20 MHz.
The following rule applies:
analysis bandwidth = 0.8 * sample rate
Remote command:
TRACe:IQ:BWIDth on page 132
Maximum Bandwidth
Defines the maximum bandwidth to be used by the R&S FSWP for I/Q data acquisition.
This setting is only available if the 320 MHz bandwidth extension option is installed on
the R&S FSWP. Otherwise the maximum bandwidth is determined automatically.
For details on the maximum bandwidth see Chapter 4.1.1, "Sample Rate and Maxi-
mum Usable I/Q Bandwidth for RF Input", on page 21.
"Auto"
(Default) All installed bandwidth extension options are enabled. The
currently available maximum bandwidth is allowed.
Note that the 320 MHz bandwidth extension may cause more spuri-
ous effects.
Note: If the 320 MHz bandwidth extension is active on the
R&S FSWP, the "IF WIDE OUTPUT" connector is automatically used
to provide IF output.
See the R&S FSWP getting started manual for details on the connec-
tor.
