A correlation method to extend the IEC 61000-4-20 for UWB measurements

摘要

This paper deals with a way to qualify and characterize transverse electromagnetic waveguides (TEM) for arbitrary transient signals. A method to determine the suitability of a TEM waveguide for various kinds of signals is presented. The specification for testing with transient waveform in Annex C of the international standard for emission and immunity testing in TEM waveguides (IEC 61000-4-20) is enhanced with time domain method, using two measured field values in the waveguide.
