The fragment of the flowchart you sent was for a USRP. For the HackRF, you need to use the Osmocom Source.
See the HackRF tutorials at https://greatscottgadgets.com/sdr/ which should get your started with Gnuradio and the HackRF. And then the Gnuradio tutorials at https://wiki.gnuradio.org/index.php/Tutorials for advance topics. The bottom line is you can only calculate the relative power - see the FAQ at https://wiki.gnuradio.org/index.php/FAQ -- Cinaed On 11/11/2018 04:45 AM, ALEJANDRO RAMIRO MUNOZ wrote: > Hey all! > > 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?
