Radiated immunity in reverberation and semianechoic rooms: Conditions for equivalence

General recommendations are given concerning the equivalence of radiated immunity testing results obtained experimentally in a semianechoic room (SAR) and a reverberation chamber (RC). The relation between the parameters influencing the results, i.e., the number of aspect angles in an SAR and the number of tuner steps in an RC has been inventoried in an extensive experimental campaign and is discussed in detail. To that purpose, an innovating canonical equipment under test), designed as a common reference equipment for standardized testing in both environments, has been constructed. The RC was equipped with two different and innovative tuning systems.
