高稳定度频率发生器的研制

The Research and Application of High Stability Frequency Generator

在相位法测距中,对调制频率、本振频率及填充频率的稳定度提出了很高的要求,本文介绍了采用锁相电路实现上述波形的原理和方法,实验结果表明:波形稳定度达到0.3ppm。

The paper introduces the principle and circuits of high stability signal sources used in distance-finder system based on precise phase way,The generator includes of module sine wave?original sine wave and square wave.0.3ppm stability has reached.
