标准摘要
[中文适用范围]： IEC 61300 的这一部分描述了表征无源设备和动态模块的群延迟特性所需的测量方法。从这些测量中可以得出更多参数，如群延迟纹波@线性相位偏差@色散@色散斜率@和相位纹波。此外，当使用解析偏振进行这些测量时，也可以确定差分群延迟，作为使用 IEC 61300-3-32 专用方法进行单独测量的替代方法。 [外文原描述]： IEC 61300-3-38:2012 describes the measurement methods necessary to characterise the group delay properties of passive devices and dynamic modules. From these measurements further parameters like group delay ripple, linear phase deviation, chromatic dispersion, dispersion slope, and phase ripple can be derived. In addition, when these measurements are made with resolved polarization, the differential group delay can also be determined as an alternative to separate measurement with the dedicated methods of IEC 61300-3-32.
