myDAQ & NI USB-6002- big delay between analog output and input on same device

[Kevin_Price]

Brief followup.  Attached is code I modified only to set the DAQmx property I mentioned.  Note that this won't change anything about your 1 second software buffer latency.   For that, you'd need a smaller software task buffer, writing fewer samples more often.

Dear all,

Thank you for all your kind information and more suggestion on my issue. it provided more ideas to solve the problem.

I managed it by increasing the rate, which makes loop runs more fast than 1 s. as additional information, i use buffer input with higher than the used rate.
