synchronizing data DAC I/0

[sconvolto]

Hi! I need to synchronize data of a DAC input and output that I'm acquiring..The DAC input seems to have a variable delay compared to the DAC output....Does anybody know how to do?

Thanks

You are trying to synchronize analog input and output on a DAQ card?  If this is the case you just need to share the sample clock between the two tasks.  Check out the Synch AI-AO example in C:\Documents and Settings\All Users\Documents\National Instruments\CVI\samples\DAQmx\Synchronization\Multi-Function\Synch AI-AO.

Hope this helps.
