Abstract(in Japanese) (See Japanese page)
Abstract(in English) A measuring instrument has been newly developed for HF-band power line noise currents emitted by electronic equipments. It consists of a pair of shielded loop probes and a 180-deg. hybrid junction to separate and measure differential-mode and common-mode noise, simultaneously, that has been difficult for the artificial mains network (AMN). Theoretical investigations are carried out on the characteristics of the instrument. Based on these analyses, a prototype instrument is made to verify the theoretical results on the mode separation and conversion characteristics. And it is proved that this measuring instrument is very useful for measurement of power line noise emitted by electronic equipments.
