The need for review of EMC emission standard

Generally the radiated emission measurement is performed in the frequency range of 30 MHz to 1000 MHz as per the commercial EMC standards. The conducted emission measurement is done in the frequency range of 150 kHz to 30 MHz. Whereas in the military standard the conducted emission measurement frequency range is from 9 kHz to 50 MHz and in the automotive standard up to 108 MHz. This paper proposes the frequency range of measurement for conducted emission from 150 kHz to 108 MHz and for radiated emission from 100 MHz to 1000 MHz. This paper also discusses the advantages of choosing the frequency band from 100 MHz to 1000 MHz for radiated emission measurement and additional issues that need to be addressed due to the change in the measurement frequency band.
