摘要
在LabVIEW环境下通过调用动态链接库(DLL)函数的方法对DSO2902示波器进行了二次开发。所开发的虚拟示波器具有2路模拟量采集通道,能够实现通道选择、数据采集、数据保存与回放、频谱分析、李沙育图形及波形参数测量功能。仪器前面板界面友好,操作方便。本开发对于LabVIEW驱动非NI公司硬件设备具有参考价值。
This paper secondarily developed the DSO2902 oscilloscope in LabVIEW by calling dynamic link library （DLL） function. The developed virtual oscilloscope has two analog input channels and can realize many functions, such as channel selecting, data sampling, date saving, waveform redisplay, frequency spectrum analysis, Lissajons figure and measurement of waveform parameters. Besides, the instrument has a friendly interface which is convenient to operate. This development has reference value for driving hardware which is not produced by NI Corporation in LabVIEW environment.
