Method for the locating a switching circuit in production or personalization system, involves detecting an oscillation of switching circuit in response on excitation by energy pulse, and determining oscillation amplitude

摘要

The method involves generating (S1) an energy pulse in a manner such that a switching circuit excites the oscillation by the energy pulse. The oscillation of the switching circuit is detected (S2) in response on the excitation by the energy pulse. The amplitude of the detected oscillation is determined (S3). The switching circuit is located (S4) on the basis a determined amplitude. An independent claim is included for an apparatus for locating the switching circuit.
