Hi Cool,
The hardware output of the PXI-6070E board is independent of the software running in LabVIEW. Once LabVIEW sends the command to write the output buffer, the hardware will work independently of the software.
There is a certain degree of synchronization that can be accomplished using DAQ Occurrences, which uses an interrupt to indicate when a certain amount of output has been achieved. However, the difference between the DAQ board sending the interrupt and LabVIEW processing that interrupt, amounts to a period of time that doesn't enable you to perform tight synchronization.
If you are looking for output rates in the kHz, this might, however, do the trick. The problem is that there is always going to be a difference since the OS (Windows) control
s the multitasking of applications and LabVIEW. This causes LabVIEW not to run deterministically. The hardware will always output at a specific rate where as the LabVIEW will not be able to simulate completely at a specific rate.
I would take a look at DAQ Occurrences in the LabVIEW Help File. This will give you your tightest synchronization. Hope that helps.
