摘要
利用LabVIEW并以连续模拟输出方式产生信号时,存在允许重生成和不允许重生成两种模式。本文针对目前教材中不讲授这方面知识,造成学生编程中容易出错的情况,对这两种信号模拟输出模式的运行机制及优缺点进行了讨论;针对利用DAQ助手实现数据采集不能随时更新数据采集卡的采样率,指出解决此问题的一种有效做法是改用DAQmx操作函数。
Completing analog output continuously with LabVIEW,there are two modes which allows regeneration and not allows regeneration.In this paper,the operational mechanism and characteristics of the two modes are discussed in detail.Simultaneously the flaw of completing data acquisition using DAQ assistant is pointed out,that the sample rate of data acquisition card can not update.Then DAQmx functions must be used to solve this problem,and the program block diagram is also given in this paper.
