  • Abstract Open site measurement on the electromagnetic interference is the most direct and universally accepted standard approach for measuring radiated emissions from an equipment
    or the radiation susceptibility of a component or equipment. A site is qualified for testing
    EMI or not is decided by the antenna measurements. In this work, we use data from setups with di erent factors to find relations of measurement and the situation of antenna. A one change point model has been used to fit observed measurements and compare the di erences
    with two kinds of antenna (broadband antenna and dipole antenna). However, with only one change point model it may not give a suitable fit for all data sets in this work.
    Therefore, we have tried other models and applied them to the data. Furthermore, we try to set up another standard more strict than ±4dB based on statistical inference results in deciding whether a site is a better one with more precision in measuring EMI values.
    Finally, a program by Matlab with a complete analysis based on the procedure performed here is provided, so that it may be used as a standard tool for evaluating whether a site is with good measurement quality in practice.
