Sampling Oscilloscope Working and Block Diagram

September 27, 2019September 19, 2019

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 …

Dual Beam Oscilloscope & Multiple Beam Oscilloscope

September 18, 2019September 16, 2019

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 …

Cathode Ray Tube Working Principle of a CRT

September 19, 2019September 15, 2019

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 …

Dual Trace Oscilloscope or Dual Trace CTR

September 18, 2019September 14, 2019

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. …

Block Diagram of a Cathode Ray Oscilloscope

September 18, 2019September 10, 2019

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 …

Horizontal Amplifier and Sweep Generator of CRO

September 24, 2019September 10, 2019

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 …

Vertical Amplifier of Cathode Ray Oscilloscope

September 24, 2019September 10, 2019

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 …

Comparison between Electrostatic and Magnetic Deflection in a CRO

September 24, 2019September 10, 2019

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 …

Magnetic Deflection in a Cathode Ray Oscilloscope

September 19, 2019September 3, 2019

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 …

Electrostatic Deflection in Cathode Ray Oscilloscope

September 18, 2019August 18, 2019

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 …
