一种微波源调频噪声测量系统

A System of FM Noise Measurement for Microwave Sources

分析了一种微波源调频噪声测量方法的原理，根据需要研制了一套微波源调频噪声测量系统，详细给出了为保证该系统测量结果准确可靠所必需的调试步骤，并结合实际设计出一种独特的定标方法。使用该系统实测了一个２２６８ＧＨｚ锁相稳频信号的调频噪声，并对测量结果进行了讨论。

A method of FM noise measurement for microwave sources is introduced, a system of FM noise measurement for microwave sources is established, the adjustment steps to keep high accuracy of measurement are detailed, and a special calibration of measurement system is developed. The FM noise of a 22.68 GHz phase locked source is measured and the measured data are discussed.
