Hello,
the NI SCB-68A connector has several Analog Ground "A GND" and "D GND".
All Analog Grund are not connected to other Analog Ground, means when i try
to measure from one AGND to another AGND.
Does that mean that i must connect ALL AGND to my source ground or only one?
If so all AGND must connected to each other on my PCI-6225 internally. Is that the case?
Do i need to connect all digital grund or just one?
