These scopes were considered "instruments". Solid, precise, repeatable measuring devices. I have calibrated / adjusted / repaired probably a hundred of these. PMEL.

But, in 2023, $500 will buy you a good scope. It is really a USB interface for an ADC, but it is very usable. And will do things like decode digital protocols.

Design and repair of analog circuits is not as big as it was before the computer revolution.

All this old stuff is solid. HP generators and analyzers are top shelf.

But they are collectors items. Use the new, cheap throwaway test equipment on the new, cheap throwaway electronics.
