A method of automatic analysis for electro-magnetic noise (EMI noise) radiated from electronic digital equipments is described. In open-site measurements of EMI noise, t is difficult to distinguish internally radiated noise by the object equipment from externally radiated noise such as broadcast waves. In this paper, some methods solving this problem are shown based on pattern correlation in electro-magnetic radiation directivity. Furthermore, a classification of EMI noise are specified. These methods are applicable to both the measurements in shielded rooms and at the open-site.
