Model 9115-AT Automotive Test Functions
DIN 40839 (ISO 7637)
This standard insures EMC (electromagnetic compatibility) in road vehicles by
injection of supply line transients. The 9115-AT can output a 12 V or 24 V
system voltage sequence, which simulates the behavior in supply voltage
reduction caused by an engine starter motor circuits (Fig. 1).
Verify the reset behavior of your DUT at various
voltage drops.
Verify the behavior of a DUT during and after cranking.
ISO 16750-2
In order to ensure electronic systems used in a vehicle are able to function
in an automotive environment, automotive component manufacturers test
electronic modules to industry standards. The 9115-AT provides built-in
simulations compliant to these automotive test standards to help automate
and speed up development time.
This standard applies to electric and electronic systems/components
for vehicles. It describes the potential environmental conditions and
specifies tests and requirements recommended for the specific mounting
location on/in the vehicle. These test simulations include measurement
of discontinuities in supply voltage, voltage drops, tests applicable to
equipment with reset functions, and tests to insure modules do not
malfunction during an engine start routine with cranking.
