摘　　要：随着相位噪声测量技术的发展,不断有采用新技术的测量系统被开发出来,但基本的测量原理仍具有其优势并得到广泛应用。本文阐述了利用频谱分析仪测量相位噪声的几种基本方法,从原理上对测量方法进行了推导分析,并分析了每种测量方法的优缺点。在文章最后介绍了易于搭建的载波滤除测量方法,通过搭建测试平台进行实际测量验证了此方法的可行性。With the development of phase noise theory and measurement technology, more and more new measurement systems are developed, and the basic measurement theories also have their advantages and also be used. This paper expatiates several methods of phase noise measurement, discusses the principle of these methods and their advantages and disadvantages respectively. In the end, this paper introduces one easily set up method-carrier wave filtration, and analyses this method by doing experiment.
