标准摘要
[中文适用范围]： IEC 62153 的这一部分通过向电缆屏蔽层施加明确定义的电流和电压并测量感应电压以确定表面传输阻抗来确定屏蔽金属通信电缆的屏蔽有效性。使用普通高频仪器可以在几 kHz 到 1 GHz 的频率范围内进行测量。 [外文原描述]： determines the screening effectiveness of a shielded metallic communication cable by applying a well-defined current and voltage to the screen of the cable and measuring the induced voltage in order to determine the surface transfer impedance. Measurements in the frequency range from a few kHz up to and above 1 GHz can be made with the use of normal high frequency instrumentation.
