(C)Element 3-21 Local Oscillators Flashcards
1
Q
The error voltage from the discriminator is applied to the:
A
Repeller(reflector) of the klystron
2
Q
In a RADAR unit, the local oscillator is a:
A
Klystron
3
Q
What component of a RADAR receiver is represented by block 48?
A
Klystron(local oscillator)
4
Q
What devices could be used as the local oscillator in a RADAR receiver?
A
Klystron and a Gunn diode
5
Q
The klystron local oscillator is constantly kept on frequency by:
A
The automatic frequency control circuit AFC
6
Q
How may the frequency of the klystron be varied?
A
small changes can be made by adjusting the Repeller voltage and large changes can be made by adjusting the size of the resonant cavity
