Good morning, a urgent question:
are the AI GND, AO GND, D GND of the PXIe 6341 all connected to Chassis?
If I measure from chassis to one of them I get continuity (using a Fluke multimeter).
I've not found this information in any NI document I read.
Thanks.

Short: Yes.
The trick is where they are connected to reduce EMC issues 😉

Yes, they are all connected at the module.
They are all kept separate in the cable and SCB-68.
You can verify this by disconnecting the cable from the module and measuring continuity on the SCB. It should be open.
