🔍 Key Concepts

• How PPI (Plan Position Indicator) displays work, especially how the sweep rotates and how range is measured from the center outward • The role of the timing / time-base in relating distance to time on a radar display • What the sweep generation does to create a circular trace on the CRT

💭 Think About

• Ask yourself: If a perfect circle is becoming an oval, is that more likely a problem with the strength of the echo, the position of the sweep, or the calibration of distance vs. time? • Which circuit directly controls how the electron beam moves outward from the center in synchronism with transmitted pulses? • Which of these circuits would mainly affect the brightness of targets versus the shape of the range rings?

✅ Before You Answer

• Identify which circuit controls linearity and geometry of the sweep on the PPI (shape and symmetry). • Confirm which circuit mainly handles intensity/brightness of echoes rather than shape. • Confirm which circuit only adds the range markers themselves, not the underlying sweep geometry.
