| Abstract: | In order to test the electromagnetic suscePtibility （EMS） of RFID device in complex electromagnetic environment in automotive, a set of EMS test plan which is based on RFID is proposed. The plan is formulated by adopting limits measuring method. After analyzing the coupling principle of signal interference and the working environment of tested equipment, the testing items and the testing methods are determined. Then, analyzing the accuracy of testing results, and a calculation formula is used to judge the testing qualifies. Lastly, the keyless entry system was tested by this plan, and the test conclusion has been adopted by an automotive company. So the feasibility of this plan is validated. For formulating EMS test specification of RFID equipment,the plan also has some reference value. |
