摘要
本文基于信号源分析仪FSUPSO介绍了三种相位噪声的测量方法：频谱仪法、锁相环法和互相关法。通过比较三种测量方法对两种信号源相位噪声的测试结果，分析了不同方法的适用范围及互相关法对测试结果改善的前提条件，为工程实践提供了可信的指导。
The paper introduces three methods for measuring phase noise： spectrum analyzer, PLL, and cross - correlation. By comparing with the results of the three methods for testing two signal source phase noise, the pa- per analyzes the applicable scope of different methods and the preconditions of improving the test result using cross -correlation, and provides credible guidance for engineering practice.
