A solution from Spirent Communications will help reduce the development time and cost of automotive Ethernet/BroadR-Reach (BRR) systems. The AING-5000 automotive impairment noise generator reduces the cost of development by simulating noise and removing the need for electromagnetic compatibility (EMC) physical chamber testing by up to 80%. New BRR electronic control units (ECUs) require physical EMC chamber testing, and typically manufacturers are testing these ECUs up to 25 times over a three-year development cycle. This is expensive, and an EMC chamber can be difficult to schedule for testing time. The AING-5000 can perform advanced modeling of a diverse range of scenarios, such as starter motor on/off or electromechanical switch on/off settings. Also available are pre-recorded noises and user-selectable parameters such as duration, burst, spacing, and power. Users can also create customizable noise libraries, and the system can be programmed to offer automated testing.
