Development of a multiport test bench and systematic measurements of cable bundles for automotive EMC tests

[摘要] In this paper the development of a cable bundle test bench is described andexemplary results of the systematic measurement of cable bundles forautomotive EMC tests are presented. The test bench consists of particularlydeveloped adapter boxes and switch matrices, which allow together with anetwork analyzer to perform a network analysis with up to 32 ports and up to1 GHz. Calibration and deembedding procedures are described and validated.Cable bundles that are characteristic to automotive EMC tests areinvestigated with respect to the number of wires within the cable bundle, theclass of the cable bundle and the type of wires.
