Method and apparatus for testing an immunity to electromagnetic interference and apparatus for irradiating radio waves for immunity test.

摘要

The invention provides an apparatus for measuring an electromagnetic wave stress of an article (6) including an electromagnetic wave irradiation unit (1) comprising a plurality of radiation probes being so arranged as adjacent to each other and approximately along a surface of the article (6) at least in one side thereof so as to permit the probes to irradiate independently electromagnetic waves on divided local areas in a surface of the article (6) and the divided local areas corresponding to the probes. The apparatus also includes a control unit being electrically connected to the article for receiving output signals having informations as to existences of any abnormalitie in individual divided local areas in the article exposed to an electromagnetic wave irradiation, the control unit (3) being electrically connected to the transmitter unit for controlling operations of the transmitter unit to control independently an excitation of each of the radiation probe. <IMAGE>
