This is background: I have a self-made PCB, which is used to connect the camera via the CameraLink interface. When I connected everything together, it turns out that the camera is signalling me via LED an error associated with the received command.... but I don't send anything yet.
I came to the conclusion that maybe if I send the correct command to it (which I am not 100% sure, I hope I have understood the documentation), it will be accepted by the camera and I will receive a confirmation. Unfortunately, the camera did not respond at all and every few seconds it shows the same error again and again. As if it hadn't noticed the command at all.
With an oscilloscope I checked that the correct signal is coming from the control unit to pin 5. Therefore, I would like to check whether I have the correct signal at the differential output. How to correctly check such a signal with a simple oscilloscope with standard probes?
