I would like to roll back the firmware revision on a MSO9254A scope to an earlier version, it is currently on 06.40.00714. There are number of changes which have been made which has an impact on usability, one of them in particular being the mess that is the way Markers are now handled.
All markers now have to at least have a name of "M", not "X1, X2, Y1, Y2" etc like they used to on 05.XX firmware. When I add manual XY markers to a waveform now, it adds 8 markers! WHY!?
