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