Comparison between GTEM and OATS radiated emission measurements for different product families

Abstract

This paper is a continuation and extension of the study camed out about correlation between the results of the radiated emission measurements in OATS and G E M , Each device has been tested using a similar procedure to the presented at the 1995 IEEE-EMC Symposium [I]. we have one followed in an ordinary test for certification, which is increased the number and types of devices used in the analysis indicated in its corresponding standard [6], [7]. To make the (in all cases they are covered by the European EMC comparison of the results of this study easier the measurement Directive). The original statistical analysis proposed in that distance was selected equal to 10 meters in all EUT. paper, is now applied in a novel way to consider the different product types separately and so leading, to a smaller The methodology of the study is detailed in the following dispersion of results. steps: METHODOLOGY OF THE STUDY
