Create Rohde & Schwarz wv file from RTSA suite IQ file
Hi good folks,
We want to create an IQ file for our R&S CMW500. It seems their native .wv format works best.
They have two nice tools that can convert from wav, iqw, and iq.tar to wv format.
I want to record an IQ stream with our Spectran V6 and RTSA Suite Pro.
My question is:
How can we convert the "File Writer" or the "Raw IQ File Writer" output formats to something R&S can handle,
ie wav, wv, iqw or iq.tar?
Cheers
To save IQ data as WAV files using the SPECTRAN V6, you can utilize the RTSA Suite's built-in functionalities:
Use the RTSAFileTool:
This command-line tool can export various formats, including WAV. You can export specific IQ files and scale the data as needed. The command would look something like this: ./RTSAFileTool export -format=wav <file.rtsa> <output.wav> The tool supports multiple WAV formats (e.g., wavF32, wavS16, wavU8), which correspond to different sample bit depths .
Record Directly from IQ Data:
You can set up a Raw IQ File Writer within the RTSA Suite. This writer can be configured to output IQ data into common formats, including WAV, by specifying the output properties during the mission setup .
Alternatively, if you wish to create a custom solution, you can use a Script Block to process the IQ data and convert it into a WAV file format, customizing any conversion parameters as per your requirements .
Additional Help on WAV Format:
Using software tools like Audacity can help convert your files to compliant formats prior to importing into RTSA.
Ty for your suggestions. An easy solution that worked for me was:
With RTSA Suite Pro
- Record to rtsa file with "File Writer"
- Open with "File Reader" and export to iq.tar
(I tried to directly export to wv but the CMW did not accept the file ("incomplete header"))
With ARB Toolbox
- Convert iq.tar to wv
Cheers
