I just love the way everything is simplified by these old programs.

Such an informative but easy to understand film, thank you

I love how they explain this in a clear and straightforward manner. To some, it may seem as dry and boring, to you I say: go watch chimps.

I also love these simple and direct explanations, I learn so much more.

One of the best explanation about CRT👍

I swear they got the same guy to narrate everything ever filmed between 1930 and 1970.

The guy narrating this I believe is George Fenneman,, the same guy who was Groucho Marx's announcer in "You bet Your Life"

Most people my age (I’m 22) would just say that the crt is something from the Stone Age I on the other hand love this old stuff

Millennials think they're still little "kids" and try to act like anything from more than 2 years ago is from the stone age. No one cares what the Skinny Jeans Generation thinks.

@Hassel 7519 that's true I admit I came off as a bit ignorant when I made that comment. I do have an an interest in CRTs and old tech in general but ofcourse not everyone does and theirs no point making an issue out of that.

informative and easy to understand, Thank you

very helpful. I watch at least 10 video but complete understanding is given by this video. Must watch video if someone really wants to have deep knowledge of CRO.

thanks for sharing this clip! is a very old but fascinating technology!

Wow, I didn't know they even had oscilloscopes back in 1943!! Very interesting!

Well, oscilloscopes have existed since at least the 1920s, and the cathode ray tube itself was invented in the 1890s (the Braun tube). In fact, the first radar displays (the old A scopes, like the ones used in the British Chain Home system) were simply oscilloscopes displaying strength of radar return signal vs time (time equating to range), with the outgoing radar pulse acting as trigger.

Good old film.

Wonderful

Hi, where can i find this footage? I'm making a documentary and need it for b-roll. Thanks!

Cool.

This video was recorded on a potato,instead of a reel to reel.

That technology will never catch on. There's no use for such a cumbersome system, even in the field of radio transmission. Next fancy trick is to get maybe two, or even three guns in one tube. That's witchcraft, I tell you.

@@georgef551Hello again! Those are LCD and CRT has many advantages over them but i guess future will bring other better stuff like micro LED displays that are apparently better than both, and if you would like to check multi electron gun displays they are called SED displays, also colored crt had 3 electron guns for each color Hope this helps

i think i'm gonna join the military

Am I the only one that wonders what you could make with multiple electron guns inside one glass vacuum chamber, pointing at one screen? I imagine you would want to change the shape of the chamber to fit the different setup, and use smaller electron guns. But imagine having different zones of the screen being updated by their own dedicated E-gun! Use four guns and you might be able to have four times the refresh rate for all I know. What limits can this be pushed to? What can miniaturization do for this technology? We have electromagnets in speakers that fin inside the ear, with coils of copper wire that's ridiculously thin. A thickness comparable to spider silk. Could we miniaturize electron guns to the point that we could have one gun per pixel, on a 1080p display of reasonable physical size? How far away from the screen does the gun actually need to be? I think the whole "tube" could be much less bulky.

You're not alone: dual beam oscilloscopes have two electron guns, color TVs have three, and a plasma TV basically has three guns per pixel.

When LCDs and Plasmas were just taking off, there was a separate screen technology being developed called the SED (surface-conduction election-emitter display), basically millions and millions of nano-sized cathode ray guns or emitters on a grid.

@nagygergely11

But over some point this is senseless, a gun per pixel would be the most inefficient LCD screen... LCD refresh rates are limited by the rate you can send the data to the pixels. This doesn't change if you change the screen technology.
