Hello Chuck,
Thank you for reviewing the traces. I'll try to count the markers in B-sweep display to make sure that the markers to be superimposed are the right ones.
Will go through the calibration again. 7834 yesterday showed its age. Had to work out the rotary switches on 7A18 and 7B53 to make it working again... Hope to finish the calibration tonight.
Looks like in order to calibrate an analog scope you need another analog scope ;)
All the Best,
Maxim
