3.2.11 Spectrum Analyzer
The spectrum analyzer can be used to assess the RF spectrum to look for any
unexpected radio interference prior to flight or to diagnose the cause of any radio
interference from other components on your model aircraft. The example
screenshot above shows an RF noise floor (the signal strength of average background
noise) of approximately -120dBm across the 433mHz band (427 – 437mHz), which is
ideal.
It is normal to see a spike on the spectrum analyzer when your DragonLink receiver
is powered on and within range.
