Does anyone have a copy of the adjustment software for the TDS744A that they could share? I have one that had its input attenuators used to repair another scope. Now I've managed find a set of attenuators in unknown condition, but it's having problems that I think might be related to calibration.
The symptoms are that on three channels the trace goes off the screen on all ranges in the most sensitive decade. Also, they will only trigger if the trigger mode is set to AC. The last channel has a small DC offset on the most sensitive ranges, triggers fine, but reads about 20% low. It also fails SPC and the acquisition self test. I know the scope worked fine with its original attenuators, so I would like to at least try calibration before I part it out.
