EMI Analyzer World-FIRST EMI solution provider Capable of perfect EMI Noise solution Enabling EMI component selection in advance Model : EA-300 Noises from EUT through LISN is displayed on EMI Receiver and the displayed noise is the mixture of Common-Mode(CM) noise and Differential-Mode(DM) noise. Because two different type of noises are shown as the mixed results, it is not-an-easy target to reach EMI solution(debugging)., causing a lot of time and effort (Try and Error). By measuring and analyzing each noise (CM & DM) respectively, the approach to the solution can be clearly correct and accurate path. The solution results – in general, EMI Filters - can be designed easier, quicker and in accurate performance. Furthermore, the solution is possible to be proved by theoretic and visual data.
