An electronic instrument that can display the changes in signal voltages graphically is known as an Oscilloscope. It is utilized to process, capture, display, analyze, store the waveform and bandwidth of the signals. The oscilloscopes are of two types based on the type of signal. These are classified into two types namely analog oscilloscope and digital oscilloscope. An Analog oscilloscope uses an electron beam to map and display the continuous variable input voltages of the signal, and a … [Read more...]
What is Cathode Ray Oscilloscope (CRO) & Its Working
Karl Ferdinand Braun has researched the concept of the elastic strings of oscillations. He used the CRT (cathode ray tube) as an electron gun through a fluorescent screen. This screen emits a spark of light. So he built the first oscilloscope namely Braun’s electrometer. Karl Braun demonstrated the first model of oscilloscope in the year 1897. Since its development, the CRO (cathode ray oscilloscope) is an essential type of oscilloscope that are mainly used for measuring different electrical c … [Read more...]
What is Dual Trace Oscilloscope : Working & Its Uses
The discovery of cathode-ray tubes happened in the year 19th century. In that period, the main intention of CRTs was mainly to explain and investigate the theory of the electron and this concept was known as cathode rays. And in the year 1897, a scientist named Karl Ferdinand Braun discovered the CRT oscilloscope. Whereas the invention of the dual-trace oscilloscope took place in the year 1930 by the British organization A.C. Cossor. The current day oscilloscope is the outcome of a various … [Read more...]
What is a Sampling Oscilloscope : Working & Its Applications
In the year 1897, the discovery of the Braun tube took place and in 1899, Jonathan included it along with magnetic field and beam developing plates in order to sweep the trace. In the initial period of 1920, cathode ray tubes were used practically for laboratory calculations but experienced bad strength of the vacuum and cathode emitters. To eliminate this drawback, Zworykin in the year 1931 discovered an approach of sealing the cathode ray tube using a thermionic emitter. This approach … [Read more...]
