The oscilloscope device, the name of which is translated from two languages as follows - "swinging" from Latin and "writing" from ancient Greek - is a device designed and designed to study the parameters of an electrical signal, which is fed to the input port or to a special tape.
Oscilloscope Applications
Modern devices allow specialists to carry out studies of a gigahertz signal. That is why the most important field of application of the oscilloscope is radio electronics, as well as its applied, laboratory and research areas. In them, using the device, specialists can monitor and study transmitted electrical signals either directly and directly, or through additional devices and media to fixing sensors. In turn, the latter transform the received influences into an electrical signal or radio waves.
Moreover, special oscilloscopes with a block for highlighting individual lines are used if it is necessary to carry out periodic or operational monitoring of indicators in television broadcasting systems.
By the way, the oscilloscope device was invented in 1893 by the French physicist André Blondel, who contributed to science in the following way. In 1893 Blondel was able to solve the problem of integral synchronization in Cornu's theory, and the bifilar oscilloscope invented by him was more powerful and was able to replace the classical stroboscope in 1891. Already in 1894, the physicist introduced the concept of "lumen" and other units of measurement, and in 1899 published a work concerning the basic theories of two armature reactions.
Oscilloscope classification principle
Devices of this type are divided into two categories according to their purpose and the method of outputting measurement information - devices with a periodic sweep for observing the signal that appears on the screen, and devices with continuous scanning, designed to record the curve, but already on a photographic tape.
There are differences among oscilloscopes in the way they process the input signal - analog and digital. There are also differences in the number of beams in devices - single-beam, double-beam, three-beam and others - up to 16 beams and even more (the latter, of course, is the rarest).
In turn, periodically scanned devices are subdivided into conventional or general-purpose, high-speed, stroboscopic, with a memory function, and specialized. Oscilloscopes are also designed, which are combined with other instruments for measurement (for example, a multimeter), and such devices are called scolometers-oscilloscopes.
