Abstract
In the electromagnetic compatibility test, the result of RE (radiation emission) is uncertain. When the result is close to the threshold, it is difficult to make an accurate judgment. CNAS-GL07 considers the influence of uncertainty on the decision and prescribes a decision method based on a single test. In this paper, Bayes rule is used to analyze the results of single RE test, which proves that there is a high possibility of misjudgment, and suggests that the number of tests should be increased to improve the reliability of the final decision. The method is improved and perfected on the basis of CNAS-GL07, and the result is good through experiment. It can provide some guidance for the determination of RE test results.
