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. |

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. |
