Experimental and computational analysis of a radiated immunity standard representativeness in the 210–216 MHz frequency range

This paper is an investigation about an Electromagnetic Compatibility test called Radiated Immunity. The goal of such test is to check if a device under test, e.g. electronic equipment, is sufficiently immune to electromagnetic noise coming from both intentional and non-intentional sources. Depending on the interference source, the field waveform might be complex, given the modern modulation and multiple access techniques. Radiated Immunity standards, however, cover only a few simple modulation schemes and test severity levels that might differ from the real field intensities. In this work, the impact of such differences in the 210–216 MHz frequency range is studied, with the use of the statistical technique Friedman Test. Experimental and computational results indicate that this difference is not negligible.
