 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 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.
