AN 200 Series

Voltage Transient Emission Test

¾

  AN 200 

¾

  AN 200B

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