Estimate of the Measurement Uncertainty of the Insertion Loss in Continuous Stirred Reverberation Chambers Including Frequency Stirring

摘要

In this paper, the standard measurement uncertainty (MU) of the insertion loss (IL) in loaded and unloaded continuous mode stirred reverberation chambers (RCs) in presence of both mechanical and frequency stirring is evaluated. The frequency stirring (FS) is essential to increases the total number of uncorrelated samples in an RC; however, when it is combined to a mechanical continuous stirring, a data preprocessing is necessary to check the total number of non-correlated samples. The methodology proposed in this paper is fast and general, i.e., it can be used for several applications of RCs. Since the loading increases the non-uniformity of fields in RCs and it affects the standard MU of the IL, results are also evaluated under the effect of a load.
