🔍 Key Concepts

• Sweep generator function in a marine radar display system • How the CRT (cathode-ray tube) displays range information horizontally across the screen • Relationship between sweep generator, sweep amplifier, and what actually reaches the CRT

💭 Think About

• Think about what a generator typically produces versus what an amplifier does in an electronic system. • Ask yourself: which part of the chain creates the basic timing/drive signal, and which part just makes that signal stronger? • Which options describe information displayed versus the electrical signal that makes the display move across the screen?

✅ Before You Answer

• Identify which choice sounds like a timing/drive function rather than display content (like range rings or antenna data). • Separate what is fed directly to the CRT cathode (video/brightness) from what controls the horizontal sweep of the electron beam. • Confirm in your mind that the sweep amplifier and the sweep generator are two different stages with different jobs.
