Our expertise in measurement and testing technology.
embeX develops, operates and supplies automated test and inspection systems, with its own laboratories covering 800m2.
We use a standardised platform, the embeX measurement platform MPL, which is based on LabVIEW and TestStand and enables efficient and flexible use. With the help of embeX MPL, we cover all phases of the product life cycle with a single platform: from use in pre-development and verification through to production and repair, after-sales and the development of product variants.
Development services.
The hardware used in each phase is based on the individual requirements. The measurement and test programmes each represent a subgroup of all available programmes. This ensures highly efficient utilisation of the measurement platform across all products through vertical and horizontal integration. Thanks to our many years of experience in measurement and testing technology, we can always customise measurement and testing systems to your individual requirements based on a large platform.

Automated test systems.
The development of high-quality embedded systems requires extensive testing and trialling. For this purpose, embeX relies on automated test systems developed in-house, which are efficiently derived from the modular embeX MPL measurement platform. It is also flexibly expandable for simple extensions to meet individual requirements. This platform is based on TestStand in combination with LabVIEW in order to guarantee an overall system that is as flexible and easy to expand as possible.
The following modules, among others, are integrated and realised in our test systems:
- Dynamic routing of measurement signals to measurement devices using a switching matrix
- Acquisition and evaluation of dynamic, transient signals
- Connection and control of test objects via various buses (IO-Link, CAN, etc.)
- Systematic evaluation of the recorded measurement data
- Connection of the test specimen using a needle adapter
- Boundary scan
In addition to the development and implementation of automatic test systems, we are also happy to support you in creating the test strategies, concepts and specifications required for verification.
Test benches.
In addition to automated test systems, embeX develops test benches for testing individual components or systems. Here, for example, the focus is on endurance test benches or testing under special environmental conditions. Due to our know-how in the field of test technology, hardware-in-the-loop test benches are also part of our expertise. Here too, embeX uses a modular framework to efficiently organise data acquisition and data handling. This is particularly important for endurance tests due to the amount of data recorded.
Own test laboratories.
embeX has laboratories and test benches covering a total area of over 800 m² with industrial trucks and a gantry crane for positioning test specimens weighing up to 1.6 tonnes.
