摘要
介绍了一种用于被动型氢钟单频调制的数字伺服电路,实现了系统的锁定,测试了中短期稳定度。最后分析了D/A的位数对其稳定度的影响。
A digital servo used in single frequency modulation of passive hydrogen maser duced. Closed loop locked of the system has been done and the short-term frequency stability tested too. At end the influence on frequency stability of the bits of D/A has been analyzed.
