 描述
  的Keysight N7784A偏振控制器包含一個高速偏振控制器+基于單片機的驅動電路。這個單位可以在不同的操作模式:
  
  作為偏振穩定器,它提供了一個穩定的輸出偏振狀態(SOP)即使有波動和漂移輸入SOP的發生例如通過溫度漂移和機械沉降過程。穩定的輸出信號是引導在一個偏振保持光纖(及);蛘咄獠侩姎夥答佇盘柨梢蕴峁┓定的SOP。
  
  作為同步擾頻器輸出信號的裝置開關SOP(偽)隨機。SOP的切換發生在幾微秒。SOP是穩定的一個預定義的時間,直到它再次切換到一個新的SOP。一個電

描述
The Keysight N7784A Polarization Controller contains a high-speed polarization controller plus microcontroller based driving circuitry. This unit can operate in various modes:
 
As Polarization Stabilizer it provides a stable output State of Polarization (SOP) even with fluctuations and drifts of the input SOP as occurring for example through temperature drift and mechanical settling processes. The stabilized output signal is guided in a Polarization Maintaining Fiber (PMF). Alternatively an external electrical feedback signal can be provided for stabilizing the SOP.
 
As Synchronous Scrambler the device switches the SOP of the output signal in a (pseudo) random way. Switching of the SOP occurs within few microseconds. The SOP is stable for a predefined time until it again switches to a new SOP. An electrical trigger input can be used to synchronize the scrambler with external events.
 
As SOP Switch the Keysight N7784A switches to a set of SOPs with high repeatability which allows customized implementations of the Mueller Matrix method for PDL characterization of components.
 
As traditional Scrambler the Keysight N7784A varies the output SOP smoothly in a random/pseudo random way.
 
The unit does not contain any moving parts and therefore is robust and withstands even rough environmental conditions. All abovementioned applications of the N7784A are supported by a PC software package
