Which component is responsible for generating the time scale or time reference in a Cathode Ray Oscilloscope (CRO)?

Explanation:

• In a Cathode Ray Oscilloscope (CRO), the component responsible for generating the time scale or time reference is the time-base generator, making option 1 the correct answer.
• The time-base generator produces a linear sweep voltage that controls the horizontal deflection of the electron beam on the screen.
• This voltage provides a time reference, allowing the CRO to display varying electrical signals over time.
• By adjusting the settings of the time-base generator, users can control the horizontal scale on the oscilloscope screen, facilitating the analysis of signal characteristics such as frequency and time intervals.
• The time-base generator is crucial for precise time-domain measurements in electronic applications.
