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.
