Thanks @attila for the explanation and I wasn't aware of the critical importance of GND. It seems that my Ch2's probe is damaged

Thanks @attila for the answer. After following your instructions, it turned out that this odd behavior only happen when the AD2's GND is connected to my testbed's GND (my microcontrollers' GND, I'm not sure if this is the right GND to connect to though!). Once, I disconnected the AD2's GND, CH2 works but I lose CAN's partial information from CH1. Example here: Any idea why would connecting GND results in losing CH2? Also, is it ok to leave the rest of GND probes and CH1&2 negatives open?

Hello again, The reason why I've calibrated my AD2 is to fix a problem. Unfortunately, calibration didn't fix it. Here is it: My AD2's Ch1 and Ch2 are connected to a CAN-L and CAN-H, respectively. Whatever is connected to Ch1 is shown on the scope, whereas CH2 does not show anything! See the two examples where the scope only shows whatever connected to Ch1 and ignore what is connected to Ch2.

Hello, I just found attila's answer in I just needed to make activate "NO LIMITS" option by ALT+F11.

Hello, I've been trying to calibrate my AD2 without luck. I followed the wizard's instructions and everything was going smoothly until I got step 5 (Oscilloscope). I connected Channels 1 and 2 P and N with ground but I get this message: "Check the connection!! The measured voltage on Oscilloscope Channel 2 is between: 2.741106966 V and 2.741734508 V It might be that the Arbitrary Waveform Generator 1 Offset is not calibrated correctly." Any idea about why it is not working? Thanks
