Keysight N7785B 是一款高速同步扰码器, 包含一个偏振控制器和基于微控制器的驱动电路。 它可作为同步扰码器、SOP 转换器和传统扰码器,在各种模式中进行工作。
作为同步扰码器,它通过(伪)随机方法转换输出信号的 SOP。 SOP 的转换仅为几微秒。
转换到新的 SOP 之前,SOP 在预定时间内非常稳定。
电子触发输入可用来使扰码器和外部事件保持同步。
再循环环路实验获得的结果主要取决于环路的 PMD 和 PDL 属性。 若要生成与已部署的系统相匹敌的结果,经证明环路同步偏振扰码方案是十分必要的。
在此类实验中,Keysight N7785B 非常适用于提供同步扰码功能。
同步扰码能力非常重要,因为它可以在环路各个阶段提供实际的偏振变化,并可同时在位列流经扰码器时提供稳定的 SOP,
从而避免位列期间由连续扰码器导致的不切实际的偏振效应快速变化。
