labview程序用6221直流恒流源和2182电压表测量霍尔效应(labview project for 6221 DC current source--Hall Effect measurement)

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 )

以开沟机为背景，程序结合了队列、通知器、状态机等多种结构，实现了参数（两个模拟量、一个脉冲量）的采集、控制的输出（模拟量输出）以及数据的保存。版本已经改为8.6版，大家一同交流学习，共同进步！(In the background trencher, the program combines the queue notifier state machine, a variety of structures, the parametric (two analog, a pulse volume) of the acquisition, the control output (analog output), and data storage . Version has been changed to version 8.6, all of them will share their knowledge and common progress!)

本vi用于从串口读取十六进制数据并保存数据至tdms文件。用户可在第二个循环中根据自己的串口数据格式进行改动。 （需要安装visa驱动）(This VI is used to read sixteen hexadecimal data from the serial port, and save data to the TDMS file.)

用labview8.5实现的调用动态库例子（DLL）。用户可以参考写自己的动态库。可能需要部分组件支持，找不到的朋友可以联系我。(using labview8.5 to call dll file.)

程序结构 《LabVIEW 程序设计从入门到精通》随书教学课件及习题（基础篇部分）(Program structure LabVIEW program from the entry to the master " with the book courseware and exercises (Basics section))

实现信号保存至文本格式，截取有用信号以便后续处理。(Save the signal to the text format and intercept the useful signal for subsequent processing.)

LabVIEW的多通道数据采集系统。本科生的毕业论文，包含全套的程序。(LabVIEW multi-channel data acquisition system. Undergraduate thesis, contains a full set of procedures.)
