Fast transient interference signals injected onto a vehicle's wiring harness through switching of associated peripheral devices can affect the correct functioning of adjacent electronic units. In conformance with the standards (ISO/SAE pulse 3a/3b), the NSG 5003 simulates these interference phenomena by means of pulse bursts. The vibrant development of electronic devices for the automotive industry means that better and faster test methods are required. The burst generator more than meets these increasing demands; its technical properties exceeding the specifications laid down in the standards by several factors. Higher pulse voltages, burst frequencies and pulse burst specifications are just part of it; there are also automated functions for weak spot analyses and long-term trials.

The EUT connection, as well as the separate connector for the coupling clamp used in data line tests, has been optimized to suit the high frequency conditions prevailing in such a fast pulse environment.
