We have 4 channels (ai0 to ai3) and we read 3 samples per channel. This means the Read NChan NSamp will output an array with 4 rows and 3 columns. The auto-indexing of the For-loop will then create a 3D Array from that. This array has 2 pages, 4 rows and 3 colums.

hemasagar, sounds like you do not have the right number of channels in your task.  Look closely at the channel constant.

Answer: D.  Nice one all.

 

So we have four channels (ai0:3), three samples per channel and two DAQmx Read operations (iterations of the loop)
