8-D-32: Fixed Range Markers
8-32D1:
Accurate range markers must be developed using very narrow pulses. A circuit that could be used to provide these high-quality pulses for the CRT is a:
Blocking oscillator.
Ringing oscillator.
Monostable multivibrator.
Triggered bi-stable multivibrator.
8-32D2:
Range markers are determined by:
The timer.
The CRT.
The magnetron.
The video amplifier.
8-32D3:
A gated LC oscillator, operating at 27 kHz, is being used to develop range markers. If each cycle is converted to a range mark, the range between markers will be:
3 nautical miles.
6 nautical miles.
8 nautical miles.
12 nautical miles.
8-32D4:
What would be the frequency of a range ring marker oscillator generating range rings at 10 nautical miles intervals?
8 kHz
24 kHz
16 kHz
12 kHz
8-32D5:
What is the distance between range markers if the controlling oscillator is operating at 20 kHz?
4 nautical miles.
1 nautical miles.
2 nautical miles.
8 nautical miles.
8-32D6:
What would be the frequency of a range ring marker oscillator generating range rings at intervals of 0.25 nautical miles?
322 kHz
161 kHz
644 kHz
1288 kHz
