基于LABVIEW软件采集电压电流信号，运用DAQmx建立任务(Acquisition of voltage and current signals)

用于labview excel写入程序（源代码）(Write program for LabVIEW excel (source code))

解决LabVIEW里不能使用数码管字体的方法 用FontCreator软件打开字体，将字体的平台由“Windows Unicode BMP(UCS-2)”改为“Windows Symbol”即可。(Method for solving LabVIEW can not use digital tube font With FontCreator software to open the font, the font platform Unicode BMP Windows (UCS-2) to Symbol Windows can be.)

简单虚拟示波器，能调节幅值，频率，相位和偏移量四种变量。(Simple virtual oscilloscope can adjust four variables: amplitude, frequency, phase and offset.)

此源程序为用Labview程序编制的，针对采集信号的功率进行分析。。(This source program is compiled by Labview program, and the power of the collected signals is analyzed..)

利用labview连接数据库，并用SQL查询访问数据库。对于初学者有很好的帮助作用。(LABVIEW SOL)

编写软件为labview2011，功能为读取txt文件中的值，并绘制电平图，设置了双游标，可以自动准确计算出两游标X轴时间差值。txt的内容为上升沿或下降沿的时间信息，首位0代表下降沿，1代表上升沿。后面位的值乘16代表沿的绝对时间(program software is the labview2011, functions is to read txt file values​ ​ , and draw level diagram, set up a dual cursors, you can automatically and accurately calculate the time difference between the two cursors X axis. txt contents of rising or falling time information, the first 0 represents falling, a representative of the rising edge. Followed by 16-bit value represents absolute time along)

基于声卡的labview虚拟示波器实例 他人做的 转载。(Sound card based LabVIEW virtual oscilloscope instance, others do reprint.)

说明：  labview产生波形并显示，对波形图表的曲线控制(Labview generates waveform and displays it, and controls the curve of waveform chart)

LabVIEW对波形求导，求导后的斜率用波形显示(LabVIEW is used to derive the waveform, and the slope after derivative is displayed in waveform)
