I'm newly using GNU Radio with a HackRF SDR as source and I want to visualice power values of a certain frequency and store them in a file for later processing in MATLAB.
I've seen in some example flowgraphs, like the one attached, there's a "Probe Avg Mag^2" box, but I don't how it works, does it store the power values somewhere? How can I visualize those values? Is there any other block for that purpose?
Thank you so much in advance,
Cheers!
Alejandro
