OSCILLOGRAPHIC – ZEM GROUP

HALOGEN LAMP FUJI JS

The history of the oscilloscope goes back to the first recordings of waveform with a galvanometer connected to a mechanical tension system in the second decade of the 19th century.

The oscilloscope was invented by the French Engineer and physicist André Blundel, who built and presented the first electromechanical oscilloscope in 1893.

This device was able to record the values of electrical quantities such as the intensity of alternating current. An oscilloscope allows you to view how voltage changes over time.

An ink pendulum attached to a coil recorded this information on a moving paper tape. The first oscilloscopes used several mechanical devices in their work process, which made their measurements not very accurate and their bandwidth was very low, between 10 and 19 kHz. A major step in the development of oscilloscopes was taken in 1897, when a German physicist, Carl Ferdinand Braun, invented a cathode ray tube (CRT). An English company named A. C. Cossor, which was the first company in the world to adopt this technology, presented its first oscilloscope in 1932.

CRT module is a special vacuum tube that contains an electron gun, a set of horizontal and vertical deflection plates, several electronic lenses and a display, covered with layers of fluorescent and phosphorescent coating on the inner side.
