It could be a recovery problem due to a broken amplifier (or other part) or an issue with a supply rail being bad causing a shift in the trigger level. Maybe even something simple like a bad connection somewhere causing a control line having the wrong value. |

Looks like a hardware issue. My local rep happened to have the same model, and could not duplicate the problem, after which he shipped it to me, and I could not cause the same problem on the loaner. Unfortunately, my scope is out of warranty and I have already had one out-of-warranty repair. My employer does not have the appetite for another repair on this scope. The local rep is lending me the scope in the meantime (thanks, Mike!) so I can complete at least some work. One thing he speculated was that something was not getting switched during the autocal sequence, so that certain attenuation values were getting autocal'd incorrectly. I may try to open the scope and see if I can clean and reseat connectors between the acquisition board and the mainboard. That won't happen anytime soon, though. This possibility is in line with nctnico's suggestion: --- Quote from: nctnico on July 07, 2022, 04:08:40 pm ---Maybe even something simple like a bad connection somewhere causing a control line having the wrong value. --- End quote --- John |
