i want to set analog output and read two analog inputs fast

[Prasun]

I am using USB 6009 for data acquisition.

I want to set analog output and read two analog inputs. Can this be done fast enough say 1000 times per second. I tried to do that but writing analog input is fast but creating analog input task and read them is slow. Can somebody help me?

You have it backwards. It's the analog output that is slow. Have you looked at the basic specs? You will never achieve a 1000 sample/Sec rate with that hardware.

If you are creating and closing a task inside a loop, stop that. Both should be done outside a loop.
