虚拟示波器

用于对于轴承振动信号的共振解调程序，便于对轴承故障信号进行分析(Used for resonant demodulation of bearing vibration signals for easy analysis of bearing fault signals)

通过设置图形的属性节点，活动曲线以及曲线是否可见来实现用复选框控制对应曲线波形的有无，非常实用！(Set graphics attribute nodes activity curve, and the curve is visible to realize the presence or absence of the corresponding curve waveform check box control, very useful!)

基于labview的单边傅里叶变换，软件实现，下载即用，无需更改(Based labview unilateral Fourier transform, software, download, no need to change)

说明：  labview 的入门程序，最好的入门资料就是自己编的小程序，供大家参考( LabVIEW)

通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

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

说明：  labview 通过OPC 访问西门子PLC(LabVIEW accesses Siemens PLC through OPC)

基于Labview下 可燃气体浓度监测软件 源码 labview 2010(Based on Labview software under the flammable gas concentration monitoring source labview 2010)

信号发生器，带扫频，带频率的切换！最小可以0.1HZ。(Frequency sweep signal generator, belt, belt frequency switch! Minimum to 0.1 HZ.)

通过user32.dll获取窗口句柄， 并模拟软件上的按钮操作(through user32.dll to acquire window api)
