The controller receives, analyzes and processes the command input by operator via the man-machine interface, to adjust and control the controllable light signal generator according to the analysis processing result and the spectrum result checked by the light checker, the controller outputs the adjustment and result via the man-machine interface to the operator, to output light signal for the result of adjustment and control on the controllable light signal generator, via the light coupler to be coupled partly and feedback to the light checker to be checked, thereby forming a closed-circuit, while the light signal coupled to the light output via the light coupler reaches user target spectrum demand.

本发明公开了一种实现光信噪比可调节的光信号源装置及控制方法，所述装置包括：控制器、人机接口、可控光信号发生器、光耦合器、光信号检测器、光信号输出口；控制器接收操作者输入给人机接口的指令并分析和处理，运用分析处理结果、并结合光检测器检测的光谱结果数据来调节和控制可控光信号发生器，控制器将调节过程和调节结果通过人机接口输出给操作者，对可控光信号发生器调节和控制的结果输出光信号通过光耦合器耦合一部分又反馈给光检测器检测，这样形成一个闭环控制，使得通过光耦合器耦合到光输出口的光信号达到用户目标光谱要求。

This paper introduces the research and implementation of all-purpose high-speed test adapter for ADC. The main contents includes two methods about how to testing the static parameters and dynamic parameters for ADC. The servo loop method is proposed to static parameters, by using the test principle of high-precision voltage source, high-precision voltage meter and digital comparator. To dynamic parameters, the DDS chip of AD9851 is used to generate sine waves with high signal to noise ratio, then the high-s...
