Hi,
最简单的方法是继续多路采集,然后利用数组操作,把某一路信号从多路信号中删掉,或者替换为“NaN”让图表类控件不显示。
如果你要节省硬件资源和系统开销,从而需要关闭某一路采集信号,那么需要硬件支持。普通的DAQ是不支持该操作的。
Good Luck!

我上传一下我的Labview VI和截图。我有三个问题想了很久没解决:
#1. How to delete one of the two channels? The reason why I want to delete it is that I want to seperate the two channels and use each channel to compare with the constant I set to decide whether to write a digital output to a corresponding device(line 5 or line 6).
#2. How to count iteration of signal 1 when "less-than sign" outputs false without stop the while loop?
#3. How to give output signal to each of the two devices(line 5 and line 6) respectively? Let's say comparision of signal 1 gives digital output to line 5, while comparision of signal 2 gives digital output to line 6.
