What is horizontal deflection system in CRO?
in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically. For that purpose a horizontal deflection plate is provided in the cro. This deflection plate is supplied with voltages , so that the electrons passing through these plates get deflected horizontally.due to alternating voltages these electrons deflect right & left very quickly, that we humans fell it is a straight horizontal line due our perception. THE voltages is provided by sweep generator,which produce ramp voltages WHICH IS AMPLIFIED & PROVIDED TO HORIZONTAL DEFLECTION PLATES in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically.

What is the unit of deflection sensitivity of cro?
The unit of deflection sensitivity of a Cathode Ray Oscilloscope (CRO) is volts per division on the vertical axis of the screen. It represents how much voltage change is needed to move the electron beam by one division vertically on the screen.

Why electromagnetic deflection is used in tv-crt rather than electrostatic as in cro?
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.

Can you use two horizontal amplifier and one one vertical amplifier in dual beam CRO?
I think you'd want just the opposite. The sweep rate is the same for both beams, so you only need one set of horizontal deflection components. But the vertical amplitudes of the two signals are generally different at the same instant of time, and you want to keep the two signals separate and distinct, so you want them running through two different vertical amplifiers.
How does the anode voltage applied to the cathode ray oscilloscope affects the sensitivity of the CRO?
The anode voltage does not affect the sensitivity of a CRO. The input amplifier and deflection circuit have a greater influence. The Anode voltage will affect the focus and visibility of the trace, in this respect it will affect how you see the result.
What is the purpose of delay line in cro?
the delay line is used to delay the incoming signal vertical information and synchorized it with the horizontal
Why it is possiple to use the CRO to measure DC-voltage?
A Cathode Ray Oscilloscope (CRO) can measure DC voltage because it converts the voltage signal into a visual representation on its screen. When a DC voltage is applied, the electron beam in the CRO is deflected vertically according to the voltage level, allowing the user to read the corresponding value on the vertical axis. By calibrating the vertical scale, the CRO can provide accurate DC voltage measurements. Additionally, the time base feature enables the display of DC signals over time, enhancing analysis.
Functions of x and y plates in cro?
deflect the electron beam on its way to the fluorescent display screen, creating waveforms on the screen
