That's almost certainly not an answer to the question you're posing, namely "How do I
measure the power of a specific class of signals".
A function probe is just a method of getting some data out of a flowgraph, and it's almost
never the appropriate solution (function probes are really more for debugging, or very
sporadically/randomly updated GUIs and such, not for signal processing).
First of all, it's important to note that basically none of the SDRs you'd attach to GNU
Radio come calibrated by default – so the numbers you see in GNU Radio are only
proportional to some amplitude of electrical field. So, digital powers are only
proportional to the powers on the air, but can easily be calculated taking the squared
magnitude of your complex samples.

Hi, you can use the Function Probe in GNU Radio to measure the Power in dBm

Hello everyone,
I'm looking for a gnuradio block or a method to determine the power of
a received
LORA signal from an arduino. Can anyone help me please?
Thank you
