Abstract :
This paper analyzes the effect of using an optic link bus converter in EMC tests. Although the optic link is used to avoid an additional conductive connection to the EUT, the interface could disturb the electromagnetic behavior of the EUT bus section. After showing several situations where the repeatability is compromised in automotive EMC tests, the paper analyzes the problem with several measurements and proposes a model to evaluate the effect. A proper position of a commercial optic bus link converter is discussed.
