Technical approaches to immunity standardization for telecommunication equipment in Japan

A method is proposed for calibrating field strength in anechoic chambers for points less than 0.8 m high. A method using a two-wire rhombic antenna is proposed for immunity testing at frequencies less than 30 MHZ. A method using a GTEM cell for testing small equipment provides the economy of standard TEM cell testing without having to use an anechoic chamber. An advanced conductive immunity test circuit is proposed which allows voltages of up to 100 V to be applied.<
