Why preamplifier is required to cathode ray oscilloscope?

to get high acceleration for the beam.


How rays can be produce by cathode ray oscilloscope?

A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display


How is the white spot formed on the screen of a cathode ray oscilloscope?

The screen is coated in a thin layer of phosphorous. This glows when bombarded by electrons.


How do you connect cathode ray oscilloscope to full wave rectifier?

To connect a cathode ray oscilloscope (CRO) to a full-wave rectifier, first, ensure the rectifier circuit is powered and functioning properly. Connect the oscilloscope probes across the output terminals of the rectifier; the positive probe should connect to the positive output, and the ground clip to the common ground. Set the oscilloscope to an appropriate voltage scale and time base to visualize the rectified waveform. Finally, observe the display, which should show the full-wave rectified signal.


Why it is sensible to have magnetic screening around the tube of cathode ray oscilloscope?

Magnetic screening around the tube of a cathode ray oscilloscope (CRO) is essential because external magnetic fields can distort the electron beam, leading to inaccurate readings and image instability. By shielding the tube from these fields, the oscilloscope can maintain precise control over the electron paths, ensuring clear and accurate waveform displays. This enhancement in performance is crucial for reliable measurements in various applications.
