Which control selects the operating range and marker interval?

Which control selects the operating range and marker interval?

• A. Brilliance control
• B. Yaw control
• C. Tilt control
• D. Range control

Answer: (D)

Range control determines how far the radar display is scaled and how the distance markers are spaced. Choosing a longer operating range shows farther out and places the markers farther apart to match that scale; choosing a shorter range narrows the view and tightens the marker spacing. This dual role is why it’s the control that selects both the operating range and the marker interval. Other controls adjust brightness (brilliance), the antenna’s vertical angle (tilt), or the radar’s orientation, but they don’t affect how far the display covers or how the range markers are laid out.
