The measurement of automotive transient emissions as per ISO 7637 requires an electronic switch, a mechancical switch and an artificial network. (The electronic switch is used to generate slow transients while the mechanical switch, a typical relay used in the vehicle, generates the fast transients. The artifical network represents the typical impedance of the wiring harness). The AN 20100N is designed for ISO 7637, CISPR 25 and CISPR 16 and can be switched accordingly.
