Our expertise in measurement and testing technology.
embeX develops, operates and supplies automated test and inspection systems, with its own laboratories covering an area of 800 m².
We utilise a uniform 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, through verification, to production and repair, after-sales and the development of product variants.
Development services.
The hardware used in each phase is based on individual requirements. The measurement and test programmes each represent a subset of all available programmes, which also ensures highly efficient use of the measurement platform across products through vertical and horizontal integration. Thanks to our many years of experience in measurement and testing technology, we can always tailor 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. To this end, embeX relies on automated test systems developed in-house, which are efficiently derived from the modular measurement platform embeX MPL. It can also be flexibly expanded for simple extensions to meet individual requirements. TestStand is used in combination with LabVIEW as the basis for this platform in order to guarantee an overall system that is as flexible and easily expandable as possible.
The following modules, among others, are integrated and implemented in our test systems:
- Dynamic routing of measurement signals to measuring devices using a switching matrix
- Recording and evaluation of dynamic, transient signals
- Connection and control of test specimens via various buses (IO-Link, CAN, etc.)
- Systematic evaluation of the recorded measurement data
- Connecting the test object using a needle adapter
- Boundary scan
In addition to developing and implementing automatic test systems, we are also happy to assist 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 trialling individual components or systems. The focus here is on endurance test benches or trialling under special environmental conditions, for example. Thanks to our expertise in testing technology, hardware-in-the-loop test benches are also part of our expertise. Here too, embeX uses a modular framework to make data collection and handling efficient, which is particularly important in endurance tests due to the amount of data collected.
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.
