Issue Details

When I use the DAQmx Timing Property Node to set the sample rate with the same connections as the DAQmx Timing VI, my program behaves differently.


The DAQmx Timing Property Node uses On Demand as Default value for Sample Timing Type, while the Timing VI uses Sample Clock.

If you want to have the same behaviour using the Property Node, you also have to set SampleTimingType to Sample Clock.

Additional Information

When you want to make advanced measurements in DAQExpress, you have to work with the DAQmx Task Property Node.
