Generate Waveform File
With enabled signal generation, triggers the instrument to store the current settings as
an ARB signal in a waveform file. Waveform files can be further processed by the ARB
and/or as a multi-carrier or a multi-segment signal.
The filename and the directory it is stored in are user-definable; the predefined file
extension for waveform files is *.wv.
If the current configuration uses coupled baseband sources and the baseband block
has more than one output, with this function you trigger the software to generate the
signals for all outputs. Created is a subset of waveform files, where the number of files
corresponds to the number the outputs and the filenames follows the structure:
<user-defined file name>_<output#-1>.wv.
Example:
Select "System Config > Fading/Baseband Config > Mode > Advanced"
Select "System Config > Fading/Baseband Config > Baseband (Tx Antennas) = 4"
Select "System Config > Fading/Baseband Config > BB Source Config > Coupled"
Select "Apply"
Select "Baseband > 5G New Radio > General > State > On"
Select "Baseband > 5G New Radio > Output/Power > Output" and observe the number
of outputs.
Select "5G New Radio > General > Generate Waveform > On"
In the "Generate Waveform" dialog, use the default directory and enter "Filename =
5gnr". Select "Save".
Select SAVE/RCL, select "File/Recall > File Manager" and in the directory tree open
the default directory.
Displayed are four files, 5gnr.wv, 5gnr1.wv, 5gnr2.wv and 5gnr3.wv.
