Test Units & Test Systems

Reliable Test systems for the Automotive Sector

When developing vehicle components and integrating them into the entire vehicle, development engineers require a large number of electronic testing and verification systems.

They also need a large number of accessories such as special cables, breakout boxes, adaptations and lots more.

These are not usually standard solutions but are the implementation of customized specifications.

Due to our extensive experience in these sectors, we have built up a kind of modular system at our site in Kirchentellinsfurt. This means that even relatively specific small units and adaptations can be offered at attractive prices.


  • Breakout boxes
  • Measuring adapters
  • Diagnostic boards
  • Simulation of electromechanical variables
  • Signal conditioning
  • Error simulation
  • Residual bus simulation for CAN, LIN, Flexray
  • HV adaptations for electric and hybrid vehicles
  • HV testing facilities
  • Testing facilities for telematic and infotainment
  • Accessories and aids for ECU engineering
  • Lab cars
  • Components of all kinds for
    • Integration HIL
    • Cluster HIL
    • Component HIL
  • OBD boxes, distributors and connecting cables

We are happy to create customized test units and test systems to correspond to your requirements.
