Note: the grids in a CRT are different from the grids in ordinary vacuum tubes: in a CRT the grids are just round holes in metal disks that surround the beam, in ordinary vacuum tubes the grids are actual wire grids in the direct path of electron flow.
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
an oscilloscope give amplitude v/s time display of a wave, whereas the spectrum analyzer gives amplitude v/s frequency display. the oscilloscope gives distribution of energy in wave with respect to time whereas the spectrum analyzer displays frequency components of a wave and their amplitudes.
A cathode ray tube is what was used in televisions and computer monitors before the advent of the LCD, LED, and Plasma tv screens. They are big, bulky, and very heavy. They are a vacuum tube, with an approximately flat face, on the inner surface of which is deposited a phosphor. When electrons from the cathode asembly reach the phosphor, they cause it to glow at that spot.
a television- like display device is called a
A cathode ray tube typically is not repairable. It is like a light bulb in that the filament may fail. If that happens, you are out of luck. If the picture is dim, a transformer used to be available from Radio Shack and other electronics suppliers, that will boost the filament voltage and increase the brightness of the picture temporarly. That is the only "repair" possible other then replacement. If you are sure the problem is a bad CRT and you have a black screen..you are out of luck for repair...
Cathode ray oscilloscope
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.

The grid in a cathode ray oscilloscope controls the electron beam that creates the waveform display. The X-plate and Y-plate are used to deflect the electron beam horizontally and vertically to create the waveform pattern. This allows the oscilloscope to accurately display and measure various electrical signals.
