I am looking for clarification on how the grounds are connected internally in the Pico 4227.
From testing the grounds on channel A and B ( when the scope is off), it looks like both channels' grounds are connected to each other.
So does it mean that :
1. when I am acquiring from both A and B simultaneously, both grounds are identical, and as a result, the two devices connected on each input have a common ground?
2. When A is on, and B is turned off: are the grounds of both channels still common or not ?
