Hello,
I am facing strange problem - I collect data with PCI 6221 DAQ Card (I read two analogic inputs at the same time, samples are being acquired due to fast counter input to which encoder is connected).
What happens from time to time is that signals are switched between two analogic inputs - I confirmed it by adding constant offset of the voltage from the device that generates analogic signals.
The biggest trouble is that it happens not in a regular way, so its hard to diagnose - I would really appreciate information if issue is rather software or hardware connected.
I attached VI's responsible for the data acquisition - I save data to global variables which are then respresented at GUI.
Thank you for any support.
BR,
Pawel
