摘要：

Certification of electromagnetic compatibility (EMC) to equipments in countries all over the world makes EMC measurement necessary in the procedure of product development. A radiated EMI measuring system is presented for objective of EMC studies. It includes two parts. The first part is constitution of the system. Equipments already existed may be used. A computer is connected with an antenna tower, a turntable and an EMI receiver or a spectrum analyzer for measurement via GPIB interface. Operators can use software to control instruments and guide measurement. The second part is controlling and measuring method. Relationships of electromagnetic emission frequency, antenna elevation and turntable azimuth with electric field are analyzed. Method is given to speed up procedure of radiated EMI measurement.
