    • In one aspect, this document provides an implementation of a system for characterizing an oscillator. This system includes an input port that receives an oscillation signal from an oscillator under test; an input port signal splitter that splits the received oscillation signal into a first oscillation signal and a second oscillation signal; a first photonic signal processing branch circuit that processes the first oscillation signal to produce a first branch output signal; a second photonic signal processing branch circuit that processes the second oscillation signal to produce a second branch output signal; a dual channel signal analyzer that receives the first and second branch output signals to measure noise in the received oscillation signal; and a computer controller that controls the first and second photonic signal processing branch circuits and the dual channel signal analyzer to control measurements of the noise in the received oscillation signal.
    • 在一个方面,本文档提供了用于表征振荡器的系统的实现。 该系统包括从被测振荡器接收振荡信号的输入端口; 输入端口信号分离器,其将所接收的振荡信号分离成第一振荡信号和第二振荡信号; 第一光信号处理分支电路,处理所述第一振荡信号以产生第一分支输出信号; 第二光子信号处理分支电路,处理所述第二振荡信号以产生第二分支输出信号; 双通道信号分析器,其接收第一和第二分支输出信号以测量接收的振荡信号中的噪声; 以及计算机控制器,其控制第一和第二光子信号处理分支电路和双通道信号分析器,以控制接收到的振荡信号中的噪声的测量结果。
