Abstract: In modern life bit commercial Electronic, industrial are defense electronics problem of electromagnetic interference (EMI) is ever growing problem. Accurate and precision measurement of EMI gives vital information about the characteristics of noise (or) EMI which leads to the achievement of electromagnetic comparability. Measurement of conducted emission is an important step towards electromagnetic comparability. Conducted emission can be measured using current probes, voltage probes depending on the applicable measurement standard. In MIL-STD461E a voltage probe method is recommended. A LISN is nothing but a voltage probe associated with impedance stabilization circuit. In the proposed paper a LISN as per MIL-STD461E studied it will be simulated using P-spice software for optimization of its performance. Based on the simulation results a compact LISN will be designed, fabricated and tested for its performance various conducted emission measurements will be carried out using fabricated LISN.
