The EM Test AN200 is used to evaluate automotive electrical and electronic components for conducted emissions of transients along battery fed or switched supply lines of a Device Under Test (DUT). A device under test which is considered a potential source of conducted disturbances should be tested according to ISO 7637 part 2.

The EM Test AN 200 includes an electronic switch for repeatable switching of inductive loads as well as an artificial network as specified in ISO.
