摘要
本文分析一种不需要参考（标准）信号源的相位噪声测量系统，该系统在被测通道里插入窄带晶体滤波器滤除被测信号的大部分噪声，作为参考信号再与被测信号进行比较，实现了信号源自身相位噪声的测量．
An new measuring system for the phase noise,without a reference signal resource,is analyzed. A narrow band-pass crystal filter is placed in the measuring channel,in order fo femove the most pant of the measured noise. And after this processing,the signal is compared with original signal, to realize the measurement of self phase noise.
