hello : i am acquiring high freq signal from two analog i/p channel of Ni 6110. But when i run the vi only one i/p is seen on the graph and the other is not. Also when the error out of one daq assistant is interchanged with error in of the other then the signal is recvedfrom the second channel. can someone explain me this and tell me how to acuire signals from both the channels simulteneously. Thank you.
akk, Give this example VI a try. I'm not sure what exactly is going on with your code, but if you use this VI with the physical channel parameter "DevX/ai0:1" where X is your device number (assigned in Measurement & Automation Explorer), you will acquire data from analog input channels 0 and 1. -Alan A.
