Simulation System

Test pulses and voltage variations according to ISO standards and manufacturer specifications

The modular simulation system is very well designed to perform immunity tests with a pulse characteristic and with line coupling injection according to the following standards:

ISO 7637, ISO 16750-2, ISO 21848
as well as manufacturer specific specifications from
BMW, Daimler Chrysler, Fiat, Ford, GMW, Mitsubishi, Nissan, PSA, Renault, SAE, VW
The system contains a 2/4 quadrant amplifier as a source and a test pulse generator including a software package SPS Automotive for testing and reporting.
As additional components a high voltage tester and a relay coupling field are available.
Operating ranges are:
U:0…60V / I:0…1000A / P:0…30kW for 12V, 24V and 42V systems

The modularly constructed Automotive Supply Simulation System is a compact EMC-Test System for the execution of immunity measurements for pulse-shaped, line conducted disturbances at electronic equipment of motor vehicles. The high performance version enables tests of current-intense consumers or even complete vehicles.

The systems consists of a 2-/4-Quadrant Amplifier, a control unit and a disturbing pulse generator.
  • The 2-/4-Quadrant Amplifier type PAS … /GN/Kfz suits as an adjustable voltage source for automotive supply simulation for 12V, 24V and new 42V especially for the generation of pulse #2b and pulse #4 for all mentioned supply voltages.


  • Optionally, the 2-/4-Quadrant Amplifier and/or a separate Load Dump Generator enable the realization of the comparatively slow disturbing pulses #5 and #7.


  • The disturbing pulse generator CAR-TESTER suits for the generation of pulse-shaped disturbing quantity pulse #1, #2a, #3 and #6.
The Road vehicle test software completes the system to an easy-to-use test equipment for applications in development and testing laboratory.
