The objective of the present invention is to provide a system and a method for evaluating inter-conductor interference of a multi-core cable, which are for measuring and evaluating inter-conductor interference characteristics of a multi-core cable in which conductors with difference characteristics and interference danger are assembled to one cable. In order to achieve the objective, the system for evaluating inter-conductor interference of a multi-core cable of the present invention includes: an input part for detecting a multi-core cable measurement result signal of a network analyzer and a noise characteristics signal of an interference source conductor and an interfered conductor of the multi-core cable measured by a noise measurement unit; a correction and quantification part for correcting shielding efficiency according to the attenuation characteristics of the cable by comparing the noise characteristics signal with a frequency domain conversion signal, and for calculating and quantifying degree of influence of the noise applied to the interfered conductor by reflecting the corrected shielding efficiency of the cable to the detected noise characteristics signal of the interference source conductor; a signal synthesis part for performing simulation of generating an interfered source waveform signal by synthesizing the quantified degree of influence of noise and a random interfered source signal; and an evaluation part for judging conformity by comparing the simulated interfered source waveform signal with a reference signal for conformity evaluation. Therefore, the system can provide accurate inter-conductor interference measurement and results in the cable by minimizing the influence due to technical knowledge and experience of an evaluator and can improve reliability of the cable by objective measurement of a multi-core cable through testing.
