(C)Element 8-24 Automatic Frequency Control-AFC Flashcards
1
Q
The AFC system is used to:
A
control the frequency of the klysrton
2
Q
A circuit used to develop AFC voltage in a RADAR receiver is called the:
A
Discriminator
3
Q
In the AFC system, the discriminator compares the frequencies of the
A
Magnetron and Klsytron
4
Q
An AFC system keeps the receiver tuned to the transmitted signal by varying the frequency of the:
A
local oscillator
5
Q
A RADAR transmitter is operating on 3.0 GHz and the reflex of klystron local oscillator operating at 3.060 GHz, develops a 60 MHz IF. If the magnetron drifts higher in frequency, the AFC system must cause the klystron repeller plate to become
A
more negative
6
Q
What component is block 50?`
A
discriminator
