(D)Element 8-32 Fixed Range Markers Flashcards
1
Q
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:
A
Blocking oscillator.
2
Q
Range markers are determined by:
A
the timer
3
Q
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:
A
3 nautical miles
4
Q
What would be the frequency of a range ring marker oscillator generating range rings at 10 nautical miles intervals?
A
8 kHz
5
Q
What is the distance range markers if the controlling oscillator is operating at 20 kHz?
A
4 nautical miles
6
Q
What would be the frequency of a range ring marker oscillator generating range rings at intervals of 0.25 nautical miles?
A
322 kHz
