Re: CRT manufacturers?


arthurok
 

hitachi might still make oscilloscope crts
hitachi was a big competitor of tek a while back.
i prefer tek instruments

Were the late 60`s and early 70`s the Halcion days for Tek? The USA put men on the Moon using this technology. I believe things, including Technology, have become more complex, but not always very much better.

I'm more worried about the overall quality of *design* of commonplace Tek
scopes. Or, in other words, show me something that has clean (12+ bits
noise-free) 1mV/div traces at 100MHz, and I'll gladly buy it. That's like
7603 but with up-to-date specs, namely digitizing, better resolution/lower
aberrations. I'm looking for something that would replace a 7603 with basic
preamps (7A26 + 7B85). Sadly enough, Tek doesn't make anything like that :
( The TDS20xx are a joke, and the digital phosphor ones (TDS30xx) are not
that much better, resolution-wise. The scopes of today are cool for digital
work, but for basic analog work they seem wholly inadequate.

It's a shame that there isn't a scope out there that would be able to do basic
multidomain testing, like checking for settling times of 12+ bit DACs. That's
a very common thing nowadays, yet they don't make scopes that would do that
(the preamps aren't good enough)! Argh. The gear of yesteryear will do all
that with some homebrew stuff attached to the front-end (see Linear app
notes), but it's really something one would hope would become commonplace in
a world where everyone and his mother are converting between analog and
digital . . . (I know, I'm just venting the frustration).

The question still stands: arthurok, China is a big country. Any hints as to
what the names of the companies may be? Even better, a website where one
could at least look at the datasheets of electrostatic CRTs in production?
I've googled around and came empty handed :(

Cheers, Kuba
