| Abstract: | A novel method for the uncertainty analysis of measurement of electromagnetic parameters by employing the flow chart of error transfer is presented. On the basis of physical and mathematical model of measurement techniques used, the practical relationship of error transfer is found and used to obtain the flow chart of error transfer, and hence estimates of uncertainty are attained using the program. The technique is illustrated with the uncertainty analysis of multi port setup for measuring electromagnetic parameters, and some important conclusions are given. The result shows that the technique is valid for the uncertainty analysis of a complicated test system. |
