数据采集编程指南 中篇

USRP收发文字包，包括不同调制方式。有频谱图显示，即时收发。(USRP send and receive text package, including different modulation schemes. There spectrogram display, send and receive instant.)

晶体的真空调频设备控制VI，通过串口于西门子PLC的通信。实现现场测量参数返回、控制命令下达、动作参数下达PLC、显示测量结果。(I edit the vacuum device control program, the programming language is LABVIEW, thanks to the example of network gods. Upload this document, hoping to provide help for later generations.)

此labview程序用于读取信号灯的设计。不错的源码 可以学习用(This LabVIEW program is used to read the design of the signal lamp. Good source code, you can learn to use)

说明：  TCP/IP通信截取指定IP和port的数据包(packet sniffer)

虚拟仪器是现代测量技术和计算机技术相结合的产物，标志着自动测试与电子测试仪器领域技术发展的一个崭新方向． 随着信息技术和计算机技术的高速发展，数字信号处理作为一门新兴的学科，其重要性日益在各个领域的应用中体现出来。本文介绍了利用LabVIEW 图形编程语言进行虚拟仪器开发的方法，设计了一种基于PC机声卡的虚拟示波器，说明了虚拟仪器在现代测试领域中的重要地位以及其广阔的发展前景． 从某种意义上说，“软件就是仪器”。(Virtual instrument is the produce that merges the computer technology and measurement technique．It stands for a brand new development directory in the field of auto-measurement and electronic measurement。 With the rapid development of information technology and the computer technology, the digital signal processing takes an emerging discipline, its importance displays day by day in each domain application. This article introduces how to develop virtual instruments using graph programming language-LabVIEW ,designs a virtual signal displayer based on PC and explains the important part and wide development prospects of virtual instrument in modern measurement technique field． In a sense, “The software is an instrument”.)

Labview调用dll文件，实现加、减、乘、除等运算，可以用来学习labview调用dll的方法。(Labview call dll file, add, subtract, multiply, divide, such as computing, the method can be used to learn labview call dll' s.)

josn格式解析子程序,可以通过调用完成josn解析(josn paratemar sadfe)

说明：  labviw开发的西洋跳棋游戏，具有完善的界面和下棋AI。尝试挑战一些吧！如果你有超级计算机的话，就可以使用本程序创建一个完美的AI完全解析棋盘的所有可能。(The checkers game developed by labviv has perfect interface and AI. Try to challenge some! If you have a supercomputer, you can use this program to create a perfect AI that fully parses all the possibilities of a chessboard.)

说明：  通过labview编写的简易计算器，可实现加减乘除等大部分运算功能(A simple calculator written by LabVIEW can realize most of the operation functions such as addition, subtraction, multiplication and division.)

能够生成正弦信号并且做FFT分析，程序可以直接使用，没有密码(Can generate sinusoidal signals and do FFT)
