Role of timing and rate in the buffered acquisition

[Somil]

Hi

I am trying a buffered acquisition. 

In the timing VI, when i specify the rate to be around 2000, i do not get any error message and the data acqusition continues. Also i am giving a time of 1000ms in the wait until next millisecond vi in the while loop.

But if i increase the rate to be around 5000 and increase the millisecond count to 2000, then i get the following error message.

-200279   DAQmx Read (Analog 1D DBL 1Chan NSamp).vi:1<append>
<B>Property: </B>RelativeTo
<B>Corresponding Value: </B>Current Read Position

<B>Property: </B>Offset
<B>Corresponding Value: </B>

What is the importance of timing in the while loop and specifying the rate in the timing VI????

Thanks.

Actually, setting the timing in while loop to 1/10 th rate in the timing VI is a good practice.I had increased the timing and as a result the buffer was getting overwritten.
