- Abstract The automotive industry has increased reliance on electronics technology and wireless communication systems and the demand for these systems are still increasing. With this demand there is a need to ensure these systems do not interfere with each other which may cause system performance degradation or even failure. Electromagnetic compatibility (EMC) is a discipline that deals with interaction between electronic and wireless systems. During the EMC testing of an electronic component the environment of the component is represented to isolate the device under test (DUT) to determine the component’s EMC characteristics. Geometric aspects of an EMC test setup may impact test results without the knowledge of the test engineer. In this paper, electromagnetic simulation and measurement results will show the impact of one of the least obvious but most often experienced issues in an EMC setup – grounding. Grounding issues will be illustrated for low frequency magnetic field, radio frequency, and conducted emissions measurements. This paper will serve as guidance to labs to visualize general testing procedures and verification procedures to provide quality data to their customers.
