Development of effective test method of radiant high frequency electromagnetic field immunity (IEC 801-3)

Abstract

For EMC (electromagnetic compatibility) of electronic equipment, it is necessary to not only reduce the electromagnetic waves radiated from the equipment but also raise the resistance against external electromagnetic waves. A test method for checking the level of this resistance against electromagnetic waves is currently under study as IEC Standard 801-3 but it has a big problem in the matter of test efficiency because of an enormous amount of test time required. Under such circumstances, we developed a simple and efficient test method which can be applied without sacrificing the reliability of the test and have the honour of reporting an outline of this method hereafter.<>
