AUTOMOTIVE TRANSIENT EMISSION MEASUREMENTS AS PER
ISO 7637-2

FOR TESTS ACCORDING TO ...

> ISO 7637-2:2004

TEST SET FOR THE MEASUREMENT OF AUTOMOTIVE TRANSIENT EMISSIONS AS PER ISO 7637

The measurement of automotive transient emissions as per ISO 7637-2 requires an electronic switch, a mechancical switch
and an artificial network. The electronic switch generates 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 200N100 is designed to meet the requirements of ISO 7637-2, CISPR 25 / ISO 11452-4 and CISPR 16-1-2 and can be
switched accordingly.

TECHNICAL DETAILS

TRANSIENT EMISSION SET - THE BENEFITS

The EM TEST Transient Emission Set consisting of the
BS 200N100 electronic switch, the artificial network
AN 200N100 and the BSM 200N40 mechanical switch is
an easy-to-use, economic and compact solution, fully
compliant to ISO 7637-2.
Small size of the equipment and short interconnections
allow to meet the distances specified by the standard.
An optional resistor box RS-Box with shunt resistor is
available for transient emission measurements as per
ISO 7637-2:2004 and ISO 7637-2:2011.
The RS-Box offers the required 40ohm shunt resistor and
other demanding shunt resistors values of e.g. 10ohm,
20ohm and 120ohm.

MULTI-PURPOSE AN 200N100

THREE-IN-ONE ARTIFICIAL NETWORK

The AN 200N100 is the multi-purpose artificial network
designed to cover four different test requirements. The
various configurations are selected by two switches. One
switch is used to configure the AN 200N100 mains input
(no capacitor as per ISO 7637-2, 1uF capacitor accross
the mains input as per CISPR 25 and ISO 11452-4 or 2uF
capacitors in series with a 1ohm resistor as per
CISPR 16-1-2). A second switch is used to switch in the
internal 50ohm termination resistor as required.
The AN 200N100 is fully adapted to the various test
requirements and shows the typical impedance
characteristics according to the different standards.
