At present there is not anything that can reliably capture the wave form for storage out of a 576. However a scope in X-Y mode tapping the vert and horizontal will do the trick. You will not be able to make quantitative measurement however due to the scope graticule not being an exact match for the tube graticule.
I have some information out there on rebuild and restoration of these units.
I would like the solve the tube issue permanently however this is currently above my skill level, but I am rapidly gain ground on it. I am thinking about tapping the preamp signal running that through an ADC Then possibly driving an LCD replacement screen as well as a digitized output for a 576 and 577.
This reminds me of my open hardware project electroporator. It's a pulse generator, (for low power pulses), with an ADC capturing each "shot". There's no need for a knob twister pulse generator like the 576, 575, 577 when you have a micropython based MCU driven pulse generator and data acquisition system already, the only outside parts needed would be adding more power and voltage capability.
The short pulses that are good for testing power semiconductors are already included in such a system. My electroporator system could be modified a little to make more powerful pulses, and the selection of series resistors could be a classic knob twist, or relays and code.
Culture Shock is the name of the electroporator project.
covers how to get schematics and edit them with lepton-schematic, a FOSS schematic editor available as a package on debian based linux systems. Ask me more questions if interested.
