Proficiency Testing by Using Traveling Samples With Preassigned Reference Values

In this paper, the results of two proficiency tests of radiated emission measurements are reported. In doing this, several considerations are made concerning the design and realization of the traveling samples, the determination of the reference values and the selection of the statistics through which the performance of the participants to the proficiency test is assessed. Emphasis is placed on the advantages stemming from the assignment of a reference value and its uncertainty to the traveling sample before the start of the proficiency test and based on numerical predictions carried out assuming different test environments and distances between the radiator and the receiving antenna.
