| 摘 要： | 根据被动型氢钟数字伺服系统的特点,设计并实现了高精度数字伺服系统。硬件电路采用了高速DSP处理芯片,两种DA转换芯片组合实现了最小步长10μV范围10 V的控制输出,高速AD转换芯片可以满足被动型氢钟慢速调制和快速调制的要求。整个系统以较低的代价达到了设计要求,并进行了硬件测试,结果表明控制电路满足输出要求。

| Abstract: | A high precise frequency controller circuit was designed according to the character of passive hydrogen maser.A high speed DSP processor is used in the circuit board.Two kinds of DA chips together makes the output volt changes in a 10 μV step from 0 V~10 V.It suffices the design needs with lower price,and satisfies the output needs after test. |
