¹ The received signal amplitude resulting from the gain setting varies over the frequency band and among devices.
² Frequency accuracy is based on temperature-compensated crystal oscillator (TCXO) vendor specifications and is not measured. Alternatively, you can incorporate an external reference source to provide a more precise frequency Reference Clock and to achieve better frequency accuracy.
