瞬时频率指示器的频率校正

分析瞬时频率指示器的频率校正技术，着重介绍了相位的温度漂移的校正，借鉴传统的温度校码方法，提出一种以常温编码为基础，以编码移动和扩展为手段的低位扩展校正技术，彻底解决了相位的温度漂移造成的测频错误，同时大大地减少了调试的工作量。

Frequency Correcting Technique of Instantaneous Frequency Indicator

The frequency correcting technique of instantaneous frequency indicator is analyzed,and the temperature floating correcting of phase is proposed especially.Based on the prior temperature coding technique,a new verification technique,which is based on the traditional temperature coding and adopted code shifting and extension methods is presented.The presented technique solves the FM mistakes caused by phase temperature and reduced tuning duration time highly.
