1. A method comprising:
generating, at an external portion of a medical device, electromagnetic waves, wherein a frequency of the electromagnetic waves is varied over time between a lower limit frequency and an upper limit frequency;
measuring, as a function of the frequency of the generated electromagnetic waves, at least one parameter related to the medical device;
selecting a frequency based on the measuring; and
using the selected frequency as a carrier frequency for an inductive link between the external portion and an implantable portion of the medical device.
