This paper proposes a design method of impedance stabilization network (ISN) which can measure disturbance at balanced multiple-pair telecommunication ports for both analog and digital signal transmission. The proposed design method of ISN is studied on the basis of the equivalent circuit of ISN and the requirements for ISN. The parameters for designing of ISNs up to 100-wires are studied and determined. An ISN for 4-wire signal ports is constructed on the basis of the proposed design method, and the characteristics of the ISN are experimentally examined. The results show the ISN satisfies the requirements for ISN. Furthermore, the measurement deviation is within 1dB compared with other ISN, and the disturbance measured by the ISN shows a good correlation with that measured by a current probe.
