EMI test sites for radiated emission measurements in the 1 GHz to 18 GHz frequency range rely on free space conditions to minimize the influence of reflections on the received signal. Practically, this is achieved using shielded enclosures that are fully lined with RF absorbing material. Site validation determines the deviations from the free space conditions that are necessary to meet the acceptance criterion for performing EMI compliance measurements in a fully anechoic room. This application note covers two different approaches for showing compliance with the acceptance criterion. Download the full paper for more information.
