(1) The receiver sensitivity setting is programmable using a TI BLE stack vendor-specific API command. The default value is standard
mode.
(2) Results based on standard-gain mode.
(3) Difference between center frequency of the received RF signal and local oscillator frequency
(4) Difference between incoming symbol rate and the internally generated symbol rate
