Let me apologize in advance, but I'm new to the Discovery2 and not an analog person.
My question has to do with the Discovery2 BNC adapter board. In particular, I am talking a look at I2C signals (~400Khz) using the analog inputs. When connected to the AD2 directly, I get the expected signal going from rail to rail. When connected through the BNC adapter and scope probe (jumpers set to DC coupling) I get a distorted signal. Not sure if I can trust the BNC adapter. Any suggestions on what's going on and if it can be corrected?
