Time-domain EMI measurement systems allow to reduce the measurement time by several orders of magnitude. In this paper a realtime time-domain emi measurement system for automotive testing is presented. Automotive tests require smaller frequency bins and a smaller IF-Bandwidth. In frequency domain such measurements take extremely long, sometimes they exceed the life-time of a component. A novel real-time time-domain emi measurement system is presented that reduces the time for automotive measurements by a factor of 8000. By a numerical oscillator in the signal processing unit the picket fence effect is reduced. Measurements have been performed on components and on a complete vehicle in the frequency range 30 MHz - 1 GHz. The real-time time-domain emi measurement system has been evaluated and assessed in a automotive test environment.     «
