scxi-1600 with scxi-1102c get analog input slow

scxi-1600 I have a while loop contain analog input 2 channel(I am using scxi-1102c) and calculate the tick count, I found that each iteration time is different when my delay is 20ms. How can I make each iteration to 20ms?

Hello Fat,

Are you seeing different loop times during execution?  How are you trying to time your loops?  There a lot of timing functions in the timing palette in LabVIEW.

If you do not have any timing in your loop, then LabVIEW will run as fast as your CPU will allow.  Create a while loop with no timing and view your CPU performance in the Task Manager.  Then create a while loop with a small delay (2 ms) and view your CPU performance.
