An interference energy can be carried between automotive battery supply lines and DUT signal transmission cables. In a vehicle most of the electronic modules share the same undesired RF from common supply lines resulting in harmful interference or disruption of functionality. Conductive transfer can occur through common-impedance coupling. This happens when both the noise source and susceptible circuits are connected by mutual impedance. A minimum of two connections are required because noise current must flow from a source to a load and then return to the source. The current from eachcircuit flows through both shared impedance of the power subsystem and interconnect wiring, all caused by shared metallic transmission lines. The typical shared connection is the return line.
