Abstract :
In this paper, a precompliance test-set for the measurement of conducted emissions based on a medium-level sampling oscilloscope and on a fast filtering algorithm (DFT) is presented. This system has been designed as a low-cost alternative to the typical precompliance test-sets that are based on spectrum analyzers equipped with EMC filters and peak detectors. Experimental examples of the results obtained using a sampling oscilloscope with 8 Kbytes of memory are given.
