How CRTs in Oscilloscopes Work

1940s Oscilloscope used to display the basics of how they work. Narrated by electrical engineer Bill Kornrumpf at the Edison Tech Center. To measure time and energy engineers needed to develop a new "meter". Needle meters used in the past were unable to show wave forms. For the age of radio and TV to start we needed more precise measurements. Part of the "Time" unit in the Universe of Instrumentation series. We feature historic electronics as part of programs that help young engineers learn, and other tech enthusiasts get perspective on engineering history.
See our upcoming two videos on oscilloscopes for more detail, and see our upcoming video on the TV CRTs.

Visuals really enhance the takeaway.

I thought this was Adrian's Digital Basement for a second haha. Great video! Analog is awesome

Superb Video on this aspect of electronics. Thank you Sir! 🤓

brilliant!

Can't we make mechanical Oscilloscope with Seismograph technique?

[@SimonBauer7]

probably yes, of course only at low frequency but yes i think so. but why bother when you can get a modern digital oscilloscope that can do this too.

and i thought i was a smart ass teen modifying a tv to show crude wave forms
