摘要
针对在原子钟测试测量实验过程中对仪器设备模拟电压信号进行高精度时序控制的需求,提出了一种基于LabVIEW和NI高速模拟输出卡的时序控制程序设计方法。以板载高精度采样时钟为基准,设计了可以精确控制模拟电压输出时间的LabVIEW控制方案,通过将时间控制转换为数据数量控制,实现了支持非线性变化的可定制化时序模拟电压输出,可实现在实验周期内同时对多路输出电压信号时间的任意控制,达到μs级的输出时间控制精度。
In order to meet the demand of high precision timing control for analog voltage signal of instrument and equipment in the process of atomic clock test and measurement experiment,a timing control program design method based on LabVIEW and NI high speed analog output card is proposed.Based on the high-precision sampling clock on board,a LabVIEW control scheme which can precisely control the output time of analog voltage is designed.By converting the time control into the data quantity control,the customized sequential analog voltage output supporting nonlinear change is realized.The time of multi-output voltage signal can be controlled arbitrarily in the experimental period,reaching the output time of μs level The accuracy of control.
