Q

How many deflection coils are driven by the sweep amplifier?

If the question has a related picture, it will appear here.

🔍 Key Concepts

• Sweep amplifier function in radar or cathode ray tube (CRT) displays • Role of deflection coils/plates in moving the electron beam on the screen • Difference between horizontal (time-base) deflection and vertical (range/received signal) deflection

💭 Think About

• Think about how many separate directions the electron beam must be steered to create a readable radar or CRT display. • Ask yourself: does the sweep amplifier drive the beam in only one axis, or does it need to control more than one axis to form the full trace? • Consider whether additional coils beyond the main steering directions are normally required for basic operation.

✅ Before You Answer

• Confirm what the sweep amplifier specifically drives (coils/plates) in a standard radar CRT system, not in specialized displays. • Verify how many independent deflection axes (e.g., X and Y) are needed to produce the sweep pattern in question. • Make sure you’re not counting any focus or intensity controls, only the actual deflection coils used to steer the beam.
