Cathode ray oscilloscope1/2/2024 ![]() Which of the following waveforms is seen on CRO? A 1000 Hz sinusoidal voltage is connected to both X and Y inputs of a CRO. A compensated probe of a CRO contains which of the following ? A circle is found on the screen of a CRO when 2 time varying signals of same frequency and same magnitude are applied to X and Y plates of the CRO. Which one of the following is the correct statement? Active probe used in a CRO,Īnswer: Cannot couple high frequency signals What will be the pattern on the cathode ray screen? The sine wave output of a function generator is fed to both the horizontal (X) and vertical (Y) inputs of a CRO. The frequency of the signal is equal to the frequency of sweep signalĪnswer: The frequency of the signal is lower than of the sweep signal.The frequency of the signal greater than of the sweep signal.The frequency of the signal is lower than of the sweep signal.In an oscilloscope, when the unknown signal applied to the vertical plates is being synchronized with the sweep signal applied to horizontal plates, the pattern seen on the CRO screen moves towards the right. A constant gain times bandwidth productĪnswer: A constant gain times bandwidth product.A vertical amplifier for a CRO can be designed for: Move from right to the left on the screenĪnswer: Move from right to the left on the screen.During the retrace time, the electrons forming the horizontal beam. It does not allow the screen to be negatively charged.The lighter scatter from the phosphor is reduced.Its acts as a heatsink and prevents phosphor burn.A thin aluminum film is usually deposited on the non viewing side of the phosphor because, Both primary and secondary emission electrons.P1 phosphor material is used for display in CRTs for: Low amplitude signals with a fast rise timeĪnswer: High amplitude signals with a slow rise time.High amplitude signals with a fast rise time.High amplitude signals with a slow rise time.High frequency signals with a fast rise time.The horizontal amplifier should be designed for ![]() The length of deflection plates is 2 cm, the distance between plates is 1 cm and the accelerating voltages is 500 V, the deflection sensitivity is: If the distance of screen from a CRT to centre of deflection plates is 15 cm. The deflection of an electron beam on a CRT screen is 10 mm, Suppose the pre-accelerating anode voltage is halved and the potential between deflecting plates is doubled, the deflection of the electron beam will be: Post acceleration is needed in a CRO if the frequency of the signal is: A barium and strontium oxide coated cathodeĪnswer: A barium and strontium oxide coated cathode.The source of emission of electrons in a CRT is Between pre-accelerating and accelerating anodesĪnswer: Between pre-accelerating and accelerating anodes.Cathode Ray Oscilloscope (CRO) MCQ, Multiple choice question on Cathode Ray Oscilloscope (CRO), GATE Questions on Cathode Ray Oscilloscope (CRO), Objective questions with answer on Cathode Ray Oscilloscope (CRO), Engineering MCQ Multiple Choice Questions
