Real-Time Checks for Radiated Emission Measurement System

In radiation emission measurement, it is necessary to switch different types of measuring antennas or adjust the polarizations of the antennas. Therefore, there is a large risk of measurement data errors in the radiation emission measurement system. However, the current intermediate validation method used for the measurement system is time-consuming and not suitable for frequently checking the system compliance. In this paper, a real-time check method for radiated emission measurement system is proposed to achieve real-time validation of the measurement system during the measurement process. Meanwhile, the influences of the reference signals and electromagnetic wave reflections from the multi-frequency reference source device on measured data are avoided. The accuracy and reliability of the measured data can be ensured.
