摘　　要：针对运用传统的单线程技术进行虚拟仪器开发中遇到的问题,提出了一种基于多线程技术的虚拟数字信号分析仪的设计方法。在LabWindows/CVI软件开发平台上,利用多线程的调度以及多线程之间的数据传输方法,解决了传统单线程开发中遇到的界面响应速度慢、显示效果不稳定等问题,大大提高了实际检测效率,具有广泛的应用价值。To solve the problems encountered in virtual digital signal analyzer development with traditional single threading technique, the design of virtual digital signal analyzers based on multithreading was proposed. With the software development platform LabWindows/CVI, the problems of developing with traditional single threading technique such as slow response of interface and display unsteadiness were resolved by using multithreading Schedule and data transfer method. This design improved test efficiency greatly and had wild application prospects.
