The BS 200N100 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 BS 200N100 and BS 200N100.1 include an electronic switch for repeatable switching of inductive loads as specified in ISO 7637-2:2011 yet supporting former standard editions.
