Property of DAQmx Write

Specifies how DAQmx Write waits for space to become available in the buffer.

Yield (12525) Repeatedly check for available buffer space, but yield control to other threads after each check. This mode offers a balance between sampling rate and CPU efficiency.
Sleep (12547) Check for available buffer space once per the amount of time specified in SleepTime.
