Analog Discovery 2 w/Discovery BNC - grounding question

[longboard]

Hello, 

I am using the Analog Digital 2 along with the Digilent BNC board for a project.  I looked at the schematic for the Digilent BNC board and can see that the GND pins available on the pin out side of the 2x15 header are not connected to the WGND node for the waveform generator channels or the SGND node for the O-scope inputs. However WGND, SGND as well as GND nodes all seem to be connected to the ground pin for the USB connection to the AD2. So I believe all three grounds are ultimately tied together within the AD2. Is there any information available regarding the relationship put WGND, SGND and GND within the Analog Discover 2?

Thank you

Sean

Hi @longboard

The AD2 has a common ground and the separation is only on the BNC Adapter.

Thank you very much Attila.
