What we can offer you



The opportunity


In order to verify complex systems, you need reliable test solutions.


The role of the Test Equipment Definition team is to specify, deliver and support a variety of test equipment used throughout the development lifecycle of those complex systems, be it a manual switch box used for hardware testing, a fully-automated test solution to support high-rate manufacturing test, or a complex software-defined simulator developed to be used within a systems integration environment.
