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.

Is CRO an amplifier?
no cro is not an amplifier.....its cathode ray osiloscope
What is magnetic deflection senstivity?
Magnetic deflection sensitivity of a cathode ray oscilloscope (CRO) is defined as the amount of deflection of electron spot produced when a magnetic flux density of 1 Wb/m2 is applied. SM = (e / m )1\2 x 1\ (2V0) 1\2 x l x L
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.
What is deflecting magnet?

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.
How does the position of the plates affect the sensitivity of the Cahtode Ray Oscilloscope?
The position of the plates in a Cathode Ray Oscilloscope (CRO) affects sensitivity by altering the electric field that influences the electron beam's trajectory. When the plates are closer together, the electric field strength increases, allowing for a more pronounced deflection of the beam for a given voltage, which enhances sensitivity. Conversely, if the plates are positioned farther apart, the electric field is weaker, resulting in less deflection and reduced sensitivity. Adjusting the plate position helps optimize the CRO for different signal amplitudes and frequencies.
What is the deflection sensitivity of a cathode ray oscilloscope?
It is the deflection on the screen (meter) per volt of deflection
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.

Why time base circuit is used in a CRO?
It is used as the horizontal deflection voltage of the CRT.
What is deflection sensitivity of a cathode ray oscilloscope?
Depends on the design of the 'scope and it's "X" & "Y" deflection amplifiers.
What is called the winding around the CRT yoke that deflects the electron beam with its magnetic field?
It's called a deflection coil. If a c.r.t. uses magnetic deflection, there will be two deflection coils, a horizontal one and a vertical one.
What are two factors whirch can enhance electron deflection in magnetic field?
Increasing the strength of the magnetic field and increasing the velocity of the electron are two factors that can enhance electron deflection in a magnetic field. This is because a stronger magnetic field exerts a greater force on the electron, while a higher velocity leads to a larger deflection due to the interaction with the magnetic field.
