本文对振荡器由于短期的不稳定性使其性能在许多应用中受到限制的状态进行了分析。此分析为建立短期稳定度的理论公式,短期稳定的定义和描述短期不稳定性的测量技术的发展提供了指南。本文讨论了影响短期稳定的因素,并提出了进行理论分析的基本模型。在研究“稳定”信号源的输出特性时使用了这些模型。提出了测量技术,并与其它研究者采用的技术进行比较。 In this paper, the oscillator is analyzed for its limited performance in many applications due to short-term instability. This analysis provides guidance for establishing theoretical formulas for short-term stability, for short-term stable definitions, and for measuring short-term instability. This article discusses the factors that affect short-term stability and presents the basic model for theoretical analysis. These models are used when studying the output characteristics of “stable” sources. The measurement technique is proposed and compared with the techniques used by other researchers.
