Can i mix the AI mode (DIFF, RSE..) on PCI-6229?

I want to known if it is possible to mix the mode off the AI .3 AI's in DIFF Mode and 3 AI's in RSE Mode.

 

If OK,will it affect signals of different channel ? 


Thank you

You can configure some of your channels for differential and some for RSE within a single task.  As long as all of your signals are grounded properly, you shouldn't run into any problems.

Can I use differential mode if the voltages I want to measure the difference of are <10V w/ respect to the AI GND?

 

The differential measurement shouldn't be more than 1-2V apart from each other, I'm just not sure if putting in a voltage so far away from AI GND will cause the ADC's to malfunction.
