Hello, I am working with a Analog Discovery 2 and need help figuring out how to get time to start at 0 in the scope display of a square wave signal I am sending to a camera for external triggering. I have attached two images of what I am using as a trigger signal, and what I am receiving in the scope out of the camera. The waveform being received from the camera matches that of the wave form being sent to it, however the signal on the oscilloscope starts around -750 to -500 ms, when I want it to start at 0 ms. I have done a calibration of the device which was successful, and I have found this line from the user manual stating: "The Oscilloscope offset error can be compensated in the Scope Instrument under Time and Channel Options, Zero offset." I cannot find the Time and Channel options anywhere in the software. I'm sure this is an easy fix, but I can't seem to get the solution to this problem, if anyone has any ideas on this, I would be very appreciative. Thanks!
