NI 6124 AI GND

[peterjo]

Hi

I have a question about the AI GND signals on the NI 6124,
is the pins AI 1 GND, AI 2 GND, AI 3 GND and AI 4 GND connect to the same ground? 

Or is the AI GND pins isolated from each other?

Yes, the AIGND are internally connected

Ok, thanks, do you also know if AI GND is connected to AO GND on the NI 6124?

Again, Yes, they are connected. However since every current (incl. ground loops) in a PCB trace create a small voltage drop in that trace, it is recommended to use the according GND connector.
