Now that we've got the citation format converted to the arcane and scary Harvard format, no-one will ever add a reference again. Hey usuability team, how about making references and citations easier instead of moving aruond the tabs on the screen? -- Wtshymanski ( talk) 19:23, 19 January 2011 (UTC)
Are the different manifacturers represented reasonably equally? Tektronics seems very prominent, also in the main Oscilloscope page, and this may be for a good reason? Perhaps getting a list of oscilloscope manifacturers/models eventually would improve the situation.

"Oscilloscopes became a much more useful tool in 1946 when Howard Vollum and Jack Murdock invented the triggered-sweep oscilloscope, Tektronix Model 511. Howard Vollum had first seen such 'scopes in Germany."
So, Vollum and Murdock are NOT the inventors of triggered scope, but German engineers are. — Preceding unsigned comment added by 95.27.226.53 ( talk) 20:33, 10 October 2011 (UTC)
Sorry, folks, but the illustration is more like a cartoon than a representative image. Shapes and proportions are unrealistic.
Worst of all, extremely few 'scopes used magnetic focus. There was no need to! Focus coils are relatively costly, heavy, and consume power. 'Scope CRTs were universally focused electrostatically.
[Decades ago, I vaguely recall a mention of a large-screen classroom 'scope with magnetic deflection, and probably focus, but its deflection amplifiers were narrow-band, probably a few tens of kHz at best. However, this was obscure (if it even existed!) and not made in any quantity.]
The shape of the envelope (bulb) is, well, almost goofy. Sorry. The neck of a real CRT is a fairly long cylinder, and the main bulb is either a narrow cone or like an ogive. What's shown is severely foreshortened. A typical 'scope CRT would have a length of three or four screen diameters.
Deflection plates are not grouped as shown. Plate pairs for one axis are a different distance from the "base" relative to the other pair.
A 'scope CRT's electron gun is understood to include the focusing structure and the deflection plates. What's shown is much too simple. Nikevich 01:58, 18 August 2015 (UTC)
