1. A method for operating a communications device that communicates via inductive coupling, the method comprising:
- adjusting a configuration of the communications device in response to a clock signal that is synchronized to a received clock signal;
obtaining information that corresponds to transmission current or power generated in response to the adjusted configuration; and
quantifying a detuning condition as a transmitter impedance ratio that indicates a communications performance of the communications device with respect to a corresponding counterpart communications device in response to the obtained information, wherein the transmitter impedance ratio is between a first transmitter impedance when the corresponding counterpart communications device is within a predefined communications range of the communications device and a second transmitter impedance when there is no corresponding communications device within the predefined communications range of the communications device.
