Specifies how DAQmx Read waits for samples to become available.

Data type: datatype_icon

Name Value Description
Wait For Interrupt 12523 Check for available samples when the system receives an interrupt service request. This mode is the most CPU efficient, but results in lower possible sampling rates.
Poll 12524 Repeatedly check for available samples as fast as possible. This mode allows for the highest sampling rates at the expense of CPU efficiency.
Yield 12525 Repeatedly check for available samples, 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 samples once per the amount of time specified in SleepTime.
