The basic frequency, crystal, and power amplifier related settings can be obtained on the “Frequency and power”tab. The center frequency is configurable within the band supported by the development board or in any of thesupported bands of the radio in simulation mode. The radio also supports setting up the frequency as a channelnumber, which enables the user to quickly change frequency with a single API command for fast frequencyhopping. The channel spacing and the actual channel number can be defined here.
