发明名称 Method for testing transponders
摘要 A method for testing remote transponders. In the method, a radio-frequency transponder is excited by sending an excitation command having a minimum threshold transmission power with the aid of a first electromagnetic field and the response of the radio-frequency transponder to the excitation command is measured with the aid of a second electromagnetic field in order to test if a corresponding received power threshold is exceeded. One of the fields is a radiating field and the other of the fields is a reactive field. The need to test transponders separately from other transponders and the need to inactivate or screen other transponders in the vicinity of the transponder being measured is eliminated.

主权项 1. Method for testing operation of a radio-frequency transponder, the method comprising the following steps: exciting the radio-frequency transponder by sending an excitation command having a minimum threshold transmission power with the aid of a first electromagnetic field, and measuring a response of the radio-frequency transponder to said excitation command with the aid of a second electromagnetic field in order to test if a corresponding received power threshold is exceeded, wherein one of said fields is a propagating radio-frequency field and the other of the said fields is an electromagnetic near field providing an inductive or capacitive connection.
