The scope is an old 4-Channel digital scope from HP (now Agilent). It cost about a fortune when it was bought, and now I got my hands on it for a (small) donation in the barbeque fund. It needs some work (some dials’ contacts need rework, and it definitly needs a new fan that does not sound like a starting plane. But otherwise, it is still good.
It only was retired because for our next project, 2GS won’t cut it. And the amount of samples it could store was not much (for our needs), too. Still overkill for my private projects, with the bonus that I don’t need to dig through manuals, as I know this thing inside out.
