采用锁相稳频技术的信号源其输出频率具有范围宽、稳定度高及连续可调的特点。本文对一种频率锁定式信号源的控制电路,即三个锁相环电路进行了简要分析。该信号源的输出频率为10kHz～10MHz。
The use of phase-locked frequency stabilization of the signal source of its output frequency with a wide range of high stability and continuous adjustable features. In this paper, a frequency-locked signal source control circuit, the three phase-locked loop circuit were briefly analyzed. The output frequency of the signal source is 10kHz ~ 10MHz.
