Experimental study on probability threshold of electromagnetic effect of electronic equipment

It is discovered that explicit interference threshold of susceptible equipment under EMI is hardly ascertained. So in this paper, the concept of probability threshold is put forward and electromagnetic susceptibility tests on digital cameras against the ESD (Electro-Static Discharge) EMP, the square pulse and the C band HPM (High power microwave) is carried out. The EMI effects observed on the cameras and effect variable of probability threshold are presented and discussed.
