"Waveform" The data is input in its original waveform format and converted to I/Q
data in the R&S
VSE software. No additional options are required on
the R&S oscilloscope.
For data imports with large bandwidths, this format is more conven-
ient as it allows for longer record lengths if appropriate memory
options are available on the R&S oscilloscope.
"Auto" Uses "I/Q" mode when possible, and "Waveform" only when required
by the application (e.g. Pulse measurement, Oscilloscope Baseband
Input).
Remote command:
INPut<ip>:RF:CAPMode

B2000 State
Activates the optional 2 GHz bandwidth extension (R&S FSW-B2000).
Note: The R&S VSE software supports input from a connected R&S FSW with a
B2000 option installed. However, the R&S FSW interface to the oscilloscope must be
set up and aligned directly on the instrument before the R&S VSE software can start
analyzing the input.
The analysis bandwidth is defined in the data acquisition settings of the application as
usual. Note that the maximum bandwidth cannot be restricted manually as for other
bandwidth extension options.
Manual operation on the connected oscilloscope, or remote operation other than by the
R&S
VSE, is not possible while the B2000 option is active.
Remote command:
SYSTem:COMMunicate:RDEVice:OSCilloscope[:STATe]

Oscilloscope Sample Rate
Determines the sample rate used by the connected oscilloscope.
This setting is only available if an R&S oscilloscope is used to obtain the input data,
either directly or via the R&S FSW.
"10 GHz" Default for waveform Capture Mode (not available for I/Q Capture
Mode ); provides maximum record length
"20 GHz" Achieves a higher decimation gain, but reduces the record length by
half.
Only available for R&S oscilloscope models that support a sample
rate of 20
GHz (see data sheet).
For R&S oscilloscopes with an analysis bandwidth of 4 GHz or larger,
a sample rate of 20 GHZ is always used in waveform Capture Mode
"40 GHz" Provides a maximum sample rate.
Only available for I/Q
Capture Mode , and only for R&S RTP13/RTP16
models that support a sample rate of 40 GHz (see data sheet)
