Hello,
there are 2 ways:
With RSDK_demo, disable radar processing from the web server interface and select output of ADC data. The visualizer will receive a RTP stream with entire frame of ADC raw data
if you want to save that to PC you need to modify the visualizer to do so (instead of plotting the data just save to a file.)
Other way is to use 1RF_4Antenna, which by default saves data to files and just disable radar processing from config file, enable ADC output and configure the number of frames you want to dump.
best regards,
Peter
