... RX Received Signal Strength Indicator (RSSI) The LMR1 has wide range RSSI that measures the strength of an incoming signal over a range of 60dB or more. This allows assessment of link quality and available margin and is useful when performing range tests. The output on pin 5b of the module has a standing DC bias 0.5V with no signal, rising to 2.5V at maximum indication (RF input levels of -40dBm and above) ...
