The influence of measurement setups in radiated emissions testing

The Radiated emission measurement is one of the tests required in EMC testing. CISPR 25 standard specifies the frequency range and the antennas used for this purpose. In this paper, differences that appear when using different measurement antennas and different semi-anechoic chambers in radiated emissions testing on the same DUT are investigated. Results show sometimes significant differences that motivate further work on reducing uncertainties introduced by different measurement setups.
