| Abstract(in English) | Because it is often case that EMC measurement of in-vehicle equipment is made at multiple test sites, the data correlation between sites with respect to the same DUT is quite important. For this reason, analyses base on CISPR 25 edition 4 Annex J, a site correlation measurement method for in-vehicle equipment defined in 2016, have been made. As a result of analyses, some study groups including the author of this paper reported that the difference in a ground plane setup has a great effect on measurement data. In the reference model, the ground plane is idealized. In addition, analyses of the connection impedances between the counterpoise and the ground plane, the arrangement of the measurement cable, and the setup symmetry of DUT were made. Those are also disregarded in the reference model, but found to have a great effect on measurement results. In this paper, the analysis result of those factors is additionally reported. |
