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 C, "Sample rate and maximum usable
Remote command:
Analysis Bandwidth
Defines the flat, usable bandwidth of the final I/Q data. This value depends on the
defined
.
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:
Maximum Bandwidth
Defines the maximum bandwidth to be used by the R&S
FSWP for I/Q data acquisition.
Which options are available depends on which bandwidth extension options are instal-
led.
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.
"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.
"80 MHz"
Restricts the analysis bandwidth to a maximum of 80 MHz.
"160 MHz"
Restricts the analysis bandwidth to a maximum of 160
MHz. The
bandwidth extension option for 320
MHz is disabled.
Remote command:
Meas Time
Defines the I/Q acquisition time. By default, the measurement time is calculated as the
number of I/Q samples ("Record Length") divided by the sample rate. If you change the
measurement time, the
is automatically changed, as well.
For details on the maximum number of samples see also
maximum usable I/Q bandwidth for RF input"
