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.
