标准摘要
[中文适用范围]： IEC 62153 的这一部分确定了金属通信电缆屏蔽的屏蔽衰减。由于采用同心外管，测量不受圆周不规则和外部电磁场的影响。宽动态和频率范围甚至可以使用普通仪器来测试超屏蔽电缆，从低频到外部电路中定义的横波极限（大约 4 GHz）。 [外文原描述]： determines the screening attenuation as of metallic communication cable screens. Due to the concentric outer tube, measurements are independent of irregularities on the circumference and outer electromagnetic field. A wide dynamic and frequency range can be applied to test even super-screened cables with normal instrumentation from low frequencies up to the limit of defined transversal waves in the outer circuit at approximately 4 GHz.
