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..)

利用DAQ助手实现的基于LABVIEW的示波器，可通过数据采集卡实现各种波形显示和尺度调节(Use the DAQ Assistant to achieve based on the LABVIEW the oscilloscope, data acquisition card to a variety of waveform display and adjust the scale)

通过labview程序的演示，进一步掌握生产者与消费者循环，该压缩文件中包含有如何控制箱子的移动，及方向的控制等(Through the LabVIEW program demonstration, further grasp the producers and consumers of circulation, the compressed file contains how to control the moving direction of the box, and control)

通过modbus通讯协议和研华温度采集器，进行温度采集(Through modbus communication protocol and research temperature collector, temperature acquisition is conducted)

可以实现多通道物理量采集显示保存历史回顾(History Review of Multi-channel Physical Quantity Collection, Display and Preservation)
