Hi everyone
I was wondering, what is the biggest oscilloscope cathode ray tube that you know of? Not length wise, I am wondering what is the largest display area that was achievable?

Length and screen size are physically related. You can't make large, short tubes so the device depth will always be the limiting factor - it has to fit on a bench.

Big CRT TVs where pretty flat in relation to screen size so that reasoning doesn't fly.

What about those big round radar displays you see in movies.  But are they electrostatic deflection like 'scope CRTs or electromagnetic deflection like TV CRTs?
