摘　　要：本文讨论了基于“三同轴法”的多芯屏蔽视频电缆转移阻抗的测试原理和方法,据此方法我们设计给出了使用矢量网络分析仪作为信号源及接收器实现多芯屏蔽视频电缆转移阻抗测试的测量装置和测试结果,最后基于测试结果我们对多芯屏蔽视频电缆的屏蔽效能进行了验证,从而证明了多芯屏蔽视频电缆转移阻抗对信息安全的重要意义。This paper discusses the principle and method of testing of transfer impedance of multicore shielded video cables based on the triaxial method. By which the test equipment of the transfer impedance of multicore shielded video cables using of vector network analyser as the source of signal and receiver is designed and test result is given.Then the Shielding Effectiveness of multicore shielded video cables is verified based on the test result,which demonstrate the transfer impedance of multicore shielded video Cables is of significance to information safety.
