2. Oscilloscope - Wikipedia

   en.wikipedia.org/wiki/Oscilloscope

   Early high-speed visualisations of electrical voltages were made with an electro-mechanical oscillograph, [2] [3] invented by André Blondel in 1893. These gave valuable insights into high speed voltage changes, but had a frequency response in single kHz, and were superseded by the oscilloscope which used a cathode-ray tube (CRT) as its display element.

   The main differences between the non-storage, non-digital analog 2200 series are as follows: the 2200 series is mostly 2 channel, with 2245, 2246, 2247, and 2252 being the 4 channel exceptions (the two extra channels having only two vertical attenuation values). The 2335 and 2336 are 2 channel, ruggedized versions mostly made for the military.

   A PC-based oscilloscope is a type of digital oscilloscope which relies on a standard PC platform for waveform display and instrument control. In general, there are two types of PC-based oscilloscopes Standalone oscilloscopes which contain an internal PC platform (PC mainboard) – common with upper mid-range and high-end oscilloscopes

5. History of the oscilloscope - Wikipedia

   Using micro-channel plates, a variety of secondary-emission electron multiplier inside the CRT and behind the faceplate, the most advanced analog oscilloscopes (for example, the Tek 7104 mainframe) could display a visible trace (or allow the photography) of a single-shot event even when running at extremely fast sweep speeds. This oscilloscope ...
