说明：  使用usrp n210,利用Labview实现正弦信号收发，一方面可以利用labview实现实际信号在空中收发，另一方面可以检验设备正常运行。(Using USRP N210 and Labview to transmit and receive sinusoidal signals, on the one hand, it can use LabVIEW to transmit and receive actual signals in the air, on the other hand, it can check the normal operation of the equipment.)

利用LabWindows/CVI实现SCPI指令集的方法(Using LabWindows/CVI implementation SCPI command set)

使用labview实现对LED和秒表的功能，实现计时(Use LabVIEW to realize the function of LED and stopwatch and realize timing)

labvIEW串口程序大全，可以为初学者提供良好的学习机会(LabvIEW serial procedures Daquan, you can provide good learning opportunities for beginners)

利用labview开发的一个简单用户系统，但是还需要优化(The labview develop a simple user system, but also need to optimize)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

labview的截图软件 非常好用可以实现桌面截图(LabVIEW screenshot of the software is very good to use the desktop screenshot)

说明：  labview很重要的例程，适用于labview新手(it is very important for the new student of labview ,very usful)

说明：  Labview读取Excel，写入Excel(Labview reads Excel and writes Excel)

本文件为labview源文件，实现labview和PLC的通讯。(This document is labview source file, realize labview and PLC communications.)
