屏蔽衰减

GB/T15217-1994同轴电缆屏蔽衰减测量方法（吸收钳法）

Methods of measurement of screening attenuation for coaxial cables ( absorbing clamp method )

在此基础上，利用注入电流探头对同轴电缆的屏蔽衰减进行了测试分析。

Finally , the shielding attenuation of a coaxial cable is achieved by the S-matrix of an injection current probe .

最后从理论上分析了引起屏蔽罩衰减误差的若干因素，给出了这些影响因素对衰减误差的影响程度。

Next , through theoretically analyzing the factors that cause errors in the attenuation , degrees of their effect on the attenuation are given .

仔细的屏蔽通常能够衰减串模噪声，很多仪器都有内部的滤波器以进一步降低这种噪声的影响。

Careful shielding will usually attenuate normal mode noise , and many instruments have internal filtering to reduce the effects of such noise even further .
