FIELD: measurement technology. SUBSTANCE: meter has generator, valve, tested four-terminal network, four bidirectional couplers, four amplitude modulators, two electrically controlled reflecting phase inverters, four detectors and four filters. Complex S parameters of SHF nonreciprocal four-terminal network are found automatically with the use of computer as a result of analysis of signals extracted by four filters after detection. EFFECT: improved efficiency and reduced time of analysis. 4 dwg
