Abstract

An investigation of test requirements described in several standards on radiated electromagnetic susceptibility (RES) was performed. Electric field strength variations were measured in two semianechoic chambers for several positions of the transmit antenna. A study was performed to determine the proper frequency step size for RES testing. A small receiving circuit was placed in the center of several metal structures typical of a personal computer. The frequency of an incident signal was varied and the receiving circuit´s response was observed. The circuit´s response was also measured when the positions of the structures were varied
