This paper focuses on the high-frequency characteristics of DC_LISN. The high-frequency characteristic of passive inductance, capacitance and resistance is analyzed in circuit topology of DC_LISN. And their corresponding highfrequency equivalent circuit models are established. On the basis of these models, the high-frequency equivalent circuit model of DC_LISN is established. At the same time, the EUT Port Impedance, Isolation and Insertion Loss characteristic parameters of DC_LISN is proposed. Then, MATLAB simulation is used to comparatively analyze the characteristics and impact of three parameters under the influence of different parasitic parameters.
