Hello everyone, I am doing a project on myRIO-1900 (on the FPGA side). Its say's in the harware specification that the sampling rate is 500 Ksa/s, meaning that separation in time between consecutive samples is 2 us (assuming i am using only 1 channel). Now assume that we have an Analog input node inside an SCTL running at 40 MHz . My quesion is, if the SCTL finishes processing a single sample at 25 ns, what happens in the remaining period between the samples? Does labVIEW stay idle waiting for the next sample? or does it keep on reading the same value? If so, how is the SCTL by any means useful when acquiring an analog input from any application? Thanks in advance,Quick response is highly appreciated,Hazem

What I am simply trying to do is: acquire a single sample, do some processing, and then wait for the other sample. However, I asuume using the wait function would cause a very delegate situation in terms of timing. Pleas correct me if I am wrong in this assumption and suggest other ways if possible.

There is nothing wrong with adding a wait. The FPGA will be waiting for the next sample as soon as you try to do the read. I do not see any issues with timing just from your quick description.
