Abstract
A low-cost EMC precompliance test-set is essential to reduce the development costs of any electrical device. In this paper we discuss the advantages of broad-band time-domain precompliance measurement techniques applied to all types of electromagnetic interferences. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment, e.g. peak-, average-, RMS- and quasi-peak-detector mode. Since time-domain techniques allow to process the whole amplitude spectrum in parallel, the measurement time may be reduced by at least one order of magnitude. Precompliance measurement results obtained with the time-domain electromagnetic interference (TDEMI) System for conducted and radiated emissions and detailed statistical signal descriptions of all classes of electromagnetic interferences are discussed.
