Figure 3-15.—Range-step generation.
View B shows the time relationships of the voltage waveforms produced by the range-step generator.
During the sweep gate, the sawtooth generator produces a sawtooth voltage that is sent to the clipper. The
point at which the sawtooth is clipped is controlled by the range potentiometer. The clipped sawtooth is
shaped in the limiting amplifier to produce the output voltage waveform. The portion of the output
waveform from T1 to T3 is applied to the vertical-deflection plates of the indicator crt to produce the
display shown in figure 3-14.
Q7. What type of ranging circuit is most often used with a radar that requires extremely accurate
range data?
Q8. The range sweep in a range-gate generator is started at the same time as what other pulse?
Q9. Range-marker generators produce pulses based on what radar constant?
Q10. What radar scope uses a range step for range measurement?
