The variable range marker signal is normally fed to the input of the:

🔍 Key Concepts

• Radar display chain: antenna → receiver → video amplifier → display • Variable Range Marker (VRM): how the adjustable range ring is drawn on the radar screen • Which stage in the radar set modulates the returns so you can see the VRM on the scope

💭 Think About

• Ask yourself: at what point in the radar circuitry do you add information that must actually appear on the screen as a bright line or ring? • Which block in the radar chain handles the strength/brightness of the echo signal just before it goes to the display? • Would a range marker signal be more related to power supply, timing/oscillation, or to the visual representation of echoes?

✅ Before You Answer

• Identify which component directly affects what is seen on the radar screen (brightness/intensity of echoes and markers). • Eliminate any options that mainly deal with power regulation rather than display of information. • Consider which stage is responsible for handling the processed echo signal right before it goes to the indicator.
