3. 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.

LISN(Line Impedance Stabilization Network) is used in test of Conducted Emission noise measurement, carrying noises generated from power line, to EMI receiver.
LISN supply the power to EUT ; isolates the EUT from interference from external power source ; stabilizes the line impedance ; provides a 50Ohm RF output for connecting it to EMI receiver.
Design equal circuits per lines (Live and Neural in single phase)
Satisfy CISPR requirements.
As EMCIS’ own unique function, LISN has the two different mode selection, Test mode(L1 & L2) and Analysis mode (Common-Mode & Differential-Mode).
Test mode is for same application as conventional LISN and Analysis mode is for application combined with EA-2100, DM and CM mode noise separation.
