Abstract

Most automotive component level testing, and in particular European Directive 95/54 requires that under some (in practice most) conditions radiated emissions measurements from electrical/electronic sub-assemblies (ESAs) are made with the ESA under test mounted on an elevated ground plane 1 m high on a wooden table. It is shown that how this ground plane is connected to the test sites ground is very important, and that this is in fact a key issue in obtaining correlation between different open field sites and also in obtaining correlation to test results obtained in a semi-anechoic chamber
