Storing the RF-Output data
Posted: Wed Apr 17, 2024 2:40 pm
Hello everybody, I would like to ask a question regarding the stream of data from the RedPitaya to the computer.
For my application, I am sampling environmental noise, from one RF input of the Redpitaya STEMlab 125-14, on every rising edge of a 1 MHz signal at the second RF input and then generating a random signal (high or low voltages) accordingly at the RF output.
My goal now is to also send the random signal (the low and high voltages) that I generated to my PC (or even the RedPitaya SD) as it will be later needed for post-processing.
I successfully modified the averager example (http://antonpotocnik.com/?p=514765) and I can read the random signal from Python, however, I would need a continuous stream and not just a single measurement.
I tried to look into the streaming feature (https://redpitaya.readthedocs.io/en/lat ... aming.html), but unfortunately, it doesn’t work as the files that I saved are empty.
In the best-case scenario, I would also leverage this stream of data the other way around, generating the random signal at the RF output starting from a bitstring stored on my computer.
Any help would be really appreciated.
Thanks
