Data Type: uInt32
Description: Specifies the number of loop iterations that must occur before DAQmxWaitForNextSampleClock() and an NI-DAQmx Read function return any late warnings or errors. The system needs a number of iterations to stabilize. During this period, a large amount of jitter occurs, potentially causing reads and writes to be late. The default number of warmup iterations is 100. Specify a larger number if needed to stabilize the system.
