Hi,
How common is it in a scope, where you sample and hold 2 channels together....and they are not positioned properly with ref to each other in time...eg one is incorrectly time shifted? Is this common?
Say you have two signals, where they definitely pulse up at the same time.....but in the scope shot, they are not sync'd....because the scope is in error. Is this common?
Please also consider when say one channel is a big signal on 200x and 100V/sec, and the other channel is say 1V/div and on 20x magnification....is this error more likely then?
