Abstract :
A new measurement system and a mapping technique for immunity or susceptibility testing are discussed. The most unique point of the system is that the electromagnetic (EM) fields are of slowly rotating polarization controlled electronically. In this paper, methods for generating slowly rotating fields are discussed. The direction of field polarization can be varied continuously and in a short time. By combining the method with a turntable, for example, the immunity-or susceptibility-characteristic maps can be obtained easily. This visualization technique is useful to detect the immunity or susceptibility attributes at a glance and thus may make the development of products with high immunity easy
