| Summary: | 碩士 === 元智大學 === 電機工程研究所 === 89 === This thesis analyzes the uncertainty of a radiated electromagnetic interference test based on the ISO Guide. The major sources of uncertainty in the radiated electromagnetic interference test which include EMI receiver, measurement cable, load impedance mismatch and antenna factor, are measured at 27 sampled frequencies in range of 30MHz to 1000 MHz, According to the regulation of ANSI-C63.4. The mean and variance of measured data are used to calibrate the loss of a radiated electromagnetic interference test and to calculate uncertainty. Finally, the relation between the expanded uncertainty for a confidence level of 95% and EMC compliance is investigated and the cost effective of the uncertainty test is evaluated.
