The general cathode ray oscilloscope generally does not have a very wide bandwidth of operation. Hence, the direct tracing of waveforms for a very high-frequency signal may not be possible. Since the brightness and sharpness …
A dual-beam oscilloscope is somewhat similar to the dual-trace oscilloscope. The only basic difference is that there are two to separate electron beams instead of a single electron beam in the case of a dual-trace …

The cathode ray tube is the main element of a cathode ray oscilloscope. We will discuss the elements of a CTR one by one in this article. Cathode of CRT There is a heater element …
Sometimes we require to compare two different signals simultaneously. In that case, we may use two different oscilloscopes for the purpose. But it becomes difficult to trigger two different sweep generators at the same instant. …
Vertical Deflection System When we use electrostatic vertical deflection we need to feed the input signal to the horizontal plates. The input signal passes through an attenuator and a number of amplifier stages. The vertical …
Before discussing the horizontal amplifier we need discuss the basic concept of sweep generator. Because the sweep generator feeds the horizontal amplifier in a CRO. Then the horizontal amplifier feeds the vertical plates for horizontal …
We feed the signal to be analysed in the the vertical amplifier. This is to amplify the signal before feeding it to the horizontally placed y – deflecting plates. Hence, the vertical amplifier only amplifies …
A cathode ray tube may apply two types of deflection on the electron beam. These are the electrostatic deflection and the magnetic deflection. Here we will discuss the different points of the comparison between two …

Before explaining the magnetic deflection in a cathode ray oscilloscope, we need to recall our concept of the magnetic force acting on a conductor in the magnetic field. A current-carrying conductor always experiences a force …
When an electron beam passes through an electric field a deflection may occur in the beam depending upon the relative direction of the field and the beam. The electrostatic deflection in cathode ray oscilloscope occurs …
