PXIe-7856 RIO Card Hardware Question about ground pins

[Hasib_LM]

Hi

The following questions are related to PXIe-7856 RIO card hardware, more specifically on GND pins.

Are all DGND pins common DGND and tied together internally?

Are all AIGNDx pins common AIGND and tied together internally?

Are all AOGNDx pins common AOGND and tied together internally? Are these also common to AIGND?

All these pins are highlighted in the attached pinout diagram.

Thanks

Eventually, they must be internally tied together as there is no mention of isolation.

I would just treat them as if they are not tied internally and tie them together in my external wiring setup just to get a good signal integrity.
