Claim:
1. A method of testing an implantable medical device, the implantable medical device including a tuned circuit having a coil for transferring energy between the implantable medical device and another device, the method comprising: inducing, with a signal generator and a test coil connected to the signal generator, an EMF in the coil of the tuned circuit; disconnecting the signal generator from the test coil; selectively connecting the test coil to a digitizer; detecting, with the test coil and the digitizer, a resonance of the tuned circuit in response to the EMF induced in the coil of the tuned circuit; and analyzing the detected resonance over a period of time to determine a property of the tuned circuit.
