Abstract—This paper concerns the comparison between reverberation chamber (RC) and anechoic chamber (AC) measurements: In particular, the case of an immunity test is considered. A two-wire transmission line is adopted as a device under test (DUT), and the current induced on the line by the external field is monitored to construct a possible susceptibility profile. Both the averaged current over stirrer rotation and the maximum current are considered to show how robust the RC measurement is against the positioning and the orientation of the DUT inside the chamber. As expected from theory, the maximum value is related to the average one by means of the number of the independent positions of the stirrer. Finally, it is highlighted how in the RC it is possible to lose some worst case situations, related to a particular incident field polarization and incoming direction, and the underestimation of the induced current depends upon the chosen number of stirrer positions.

Abstract

Abstract—This paper concerns the comparison between reverberation chamber (RC) and anechoic chamber (AC) measurements: In particular, the case of an immunity test is considered. A two-wire transmission line is adopted as a device under test (DUT), and the current induced on the line by the external field is monitored to construct a possible susceptibility profile. Both the averaged current over stirrer rotation and the maximum current are considered to show how robust the RC measurement is against the positioning and the orientation of the DUT inside the chamber. As expected from theory, the maximum value is related to the average one by means of the number of the independent positions of the stirrer. Finally, it is highlighted how in the RC it is possible to lose some worst case situations, related to a particular incident field polarization and incoming direction, and the underestimation of the induced current depends upon the chosen number of stirrer positions.
