问题: Labview中如何使用 SCXI-1126 ?

解答:

      SCXI-1126 Frequency.vi (examples\daq\scxi\scxi1126.llb)是Labview如何使用SCXI-1126的一个例子。查看这个VI的文档以了解关于这个范例更多的使用信息。 (使用CTRL-H 进入文档帮助窗口然后把鼠标移到前面板右上角的VI图标上)。

       如果你简单的希望使用这个模块读取一个频率,那么考虑使用Acquire N Scans.vi (examples\daq\analogin\analogin.llb). 在通道输入控件中写入典型规范的SCXI通道字符串(比如:ob0!sc1!md1!0)然后运行该VI,波形图上的输出可能是0 到128,000中的任何一个值。所以如果你的频率输入是 10,000 Hz,你将会看到在图上看到10,000,你需要合适设置标尺的范围。
