摘要 针对频率计等仪器中使用温补晶振的特殊情况提出并实现了一种软件数据补偿的特殊MCXO。其补偿原理与传统的方式有所不同,它不是对振荡器进行补偿控制,而是根据温度的变化以数据方式不断修改晶体振荡器的频率标称值来达到提高准确度的目的,当该振荡器被用作标准来测量其它信号或用它产生标准时间信号时,都以其准确的频率为基础进行运算和处理。所以,这种MCXO不但远比同类MCXO简单。 Presents a MCXO for the instrument such as frequency meter. It's compensated principle is different from tranditional mode. According to temperature changes MEXO revises frequency marking value continuously to increase it's precision by means of date mode. So that very high accuracy is obtained.
