Beschreibung
Zusammenfassung:	Aspects of the disclosure are directed to auto-sweeping impedance-matching circuitry that matches an impedance of an RF antenna. As may be implemented in accordance with one or more embodiments, a transmitter that is configured and arranged to transmit signals to remote devices via the RF antenna, is used to communicate a plurality of test signals to the impedance-matching circuitry, with each test signal having a designated frequency and/or test signal pattern that is different than the designated frequency and/or test signal pattern of the other test signals. A characteristic of each of the test signals as passed through the impedance-matching circuitry is detected. For each of the test signals generated for the auto-sweep, the detected characteristic is compared to an expected characteristic for the test signal, and an output indicative of compliance of the impedance-matching circuitry with a design specification is generated and transmitted in response to the comparison.
