RadioLib SX126x Spectrum Scan
Perform a spectrum power scan using SX126x.
The output is in the form of scan lines, each line has 33 power bins.
First power bin corresponds to -11 dBm, the second to -15 dBm and so on.
Higher number of samples in a bin corresponds to more power received
The output is in the form of scan lines; each line has 33 power bins.
The first power bin corresponds to -11 dBm, the second to -15 dBm, and so on.
The higher number of samples in a bin corresponds to more power received
at that level.
The spectrum analyzer perform power measurements in the configured bandwidth.

The spectrum analyzer performs power measurements in the configured bandwidth.
The X axis represents frequency in MHZ and Y axis display actual received power in 33 dBm.
In this example above, the frequency span goes from 850 MHz to 950 MHz (that is a 100MHz range), and
the visual amplitude goes from -11 dBm to -110(-139) dBm.
To show the results in a plot, run the Python script
