Demonstrating the Combined Effects of Testing Radiated Immunity in Accordance with Edition 4.0 of IEC 61000-4-3 Using Multiple Signals


With the release of the 4th Edition of IEC 61000-4-3, questions arise concerning the multiple signal method of testing with regard to over-testing of EUTs, 3rd order harmonic issues when multiple signals are applied, and the overall time savings of applying multiple signals during a single sweep. This experiment will demonstrate and characterize the energy seen by the EUT in both the frequency and time domains, as well as demonstrate the time savings involved when testing multiple signals, display the time savings involved when testing multiple signals, and provide measurements of the power required during multiple signal testing.
