锁相技术在测控、通信、数字信号处理等众多领域得到了广泛的应用。虚拟锁相环成为锁相环发展趋势之一，根据锁相环路的基本组成及原理，利用LabVIEW软件提供的强大的数值计算和信号分析等能力对锁相环进行设计。实验和仿真结果表明该软件锁相环具有较好的捕获和跟踪性能。利用软件实现的锁相环比硬件锁相环具有更好的灵活性和通用性，同时具有结构简单、参数设计灵活等优点。(Lock-in technique in many areas of monitoring and control, communications, digital signal processing, has been widely used. Became one of the virtual phase-locked loop phase-locked loop trends, according to the basic principles of composition and phase-locked loop, using LabVIEW software provides powerful numerical calculation and signal analysis capabilities such as phase-locked loop design. Experimental and simulation results show that the software PLL has a better acquisition and tracking performance. Use of software than hardware locked loop PLL has better flexibility and versatility, but also has a simple structure, flexible design parameters, etc..)

串口数据采集RS232串口是工业中比较常用，也最容易接触到的一种总线协议，台式机上一般都有二个，而现在很多下位机、仪器等很多都还是使用串口通信的。通过RS232串口可以方便的实现Labview与其他测试软件、控制软件的通信。(Serial port data acquisition RS232 serial port is a kind of bus protocol which is commonly used in industry, and it is also the most easy to contact. In general, there are two desktop computers, and many lower computer, instrument and so on are still used in serial communication. The communication between Labview and other test softwares and control software can be conveniently realized through RS232 serial port.)
