Question 1 of 27070

Q

Range markers are determined by:

🔍 Key Concepts

• How a marine radar display builds the picture on the screen • Which component sets how long the radar "listens" for echoes after each pulse • Difference between display devices (like CRT) and timing/processing circuits

💭 Think About

• Ask yourself: which part of the radar actually controls the distance scale (range scale) you select? • Which component directly controls the time between transmitted pulse and received echo being drawn on the screen? • Are the other components mainly for generating RF energy, displaying the signal, or amplifying the signal rather than setting the measurement scale?

✅ Before You Answer

• Identify which unit controls the pulse repetition timing / sweep time that corresponds to range scales • Verify which item in the choices is responsible for time-base generation rather than display or power output • Confirm that the chosen component logically determines all available range scales on the radar
