The measurement of conducted emissions in the EMC regulation is to evaluate generated conduction noise from an electrical equipment. In the final measurement, it takes generally a lot of time due to use of a quasi peak detection receiver consisted of a charge and discharge circuit. In this article, it is reported that a faster measurement method for the conduction noise is realized by a real time spectrum analyzer and FFT digitizing process for the sampled data.
