A Timed Loop is used to create a proper timing at data acquisition. The structure is tested with a period of 1 000 ms and each loop is taking 1 000 ms except the first that elapses in a few ms. My expectation was of course 1 000 ms even for the first loop. I need the measurements to be equally separated in time from the very first point. How do I solve this? Is there any information about the behavior from NI?
