1.解压附件中的zip压缩文件到:C:\Program Files\Electronics Workbench\EWB9 目录下。
2. 打开 <Electronics Workbench\EWB9>\samples\LabVIEW Instruments\DAQ目录下的DAQ.ms9 。这个电路是一个低通滤波器电路。
3.双击XLV1以打开LabVIEW虚拟仪器的前面板。
4.保证您的硬件设置的是对的。然后点击物理通道(physical channel)选择您电脑上连接的数据采集设备和您想使用的采集通道。
5.点击采集数据(Acquire Data),将开始默认的为时0.2s的采样,采样率为1000hz。
