摘 要: 文中介绍了在LabVIEW开发环境中使用公式节点编程的方法。结合一个应用实例,通过调用公式节点编写频率控制和数据处理代码,实现对M系列多功能数据采集卡模出时的频率控制,以及对采集到的数据进行分析处理,得出被检测电路板的频率特性。通过分析测量结果证明,此方法高效可行,增强了程序的可读性和整体性能。 In this paper, the program method by using Formula Node on the LabVIEW platform is introduced. By using Formula Node to program the code of frequency controlling and data processing, it can control the frequency of the analog output signal of M-series DAQ board, and help progress the data acquired from the DAQ board, and we can get the frequency characteristic of the tested circuit board. Through analyzing the results, it proves that the method is efficient and practicable. It strengthens the readability and performance of the program.
