I have a 475 and the docs, but I don't recall seeing a schematic inside. Probably just as well, all the junk is integrated (thick film IIRC?).


Down in the schematics, it appears to be some sort of cross-coupled differential cascode?


Hmm...

I have worked for Tek, last scope I remember was 100MHz analog + 1Gsamples. They used thick film restors in the vertical output stages (quite a bit of power there). The digital part was just a x86 board (286??), but of course with fast ADC and RAM to grab stuff. Cannot remember the model number, but for the rest I think there were no thick film, but only normal transistors, in the design. Too long ago, sorry.

Yep.

Somebody will perhaps make a scope on a chip one day, with build in driver for touchscreen. Like an Iphone, networked of course.

Those touch screens seem way cool, no more buttons needed.
