| 摘 要： | 为消除信号产生器内温度变化对信号相位的影响,提出了一种恒温控制和实时相位调整相结合的方法。在这种方法中,除恒温控制外,基于对信号产生器内部温度、相位测量值变化率、设备调相分辨率和相位波动指标等的分析研究,合理计算实时相位调整关键参数,进行实时相位调整,有效地减小信号产生器内部温度变化引起的相位波动,提高了输出端信号相位的一致性和稳定性。

| Abstract: | In order to eliminate the influence of the temperature of signal generator on the phase of the time/frequency signals,a method combining temperature control and real-time phase adjustment is put forward.In this method,besides controlling the temperature,the key parameters for real-time phase adjustment are calculated based on the analyses of the temperature of signal generator,the change rate of the measured signal phase,the phase-adjustment resolution,the phase variation index,etc.Thus,the phase fluctuatio... |
