6. RF AGC Operating Voltage: V17
Input SG8 to VIF IN and gradually reduce Vi and then measure the input level when RF AGC output TP17 reaches
1/2Vcc, as shown below.

7. Capture range: CR-U
1. Increase the frequency of SG9 until the VCO is out of locked-oscillation.
2. And decrease the frequency of SG9 and measure the frequency fU when the VCO is locked.
CR-U = fU – 45.75 [MHz]
8. Capture range: CR-L
1. Decrease the frequency of SG9 until the VCO is out of locked-oscillation.
2. And increase the frequency of SG9 and measure the frequency fL when the VCO is locked.
CR-L = 45.75 – fL [MHz]
9. Capture range: CR-T
CR-T = CR-U + CR-L [MHz]
10. AFT sensitivity :
μ
, Maximum AFT voltage :
V18H
, Minimum AFT voltage : V18L
1. Input SG10 to VIF IN, and set the frequency of SG10 so that the voltage of AFT output TP18 is 3[V] . This
frequency is named f(3).
2. Set the frequency of SG10 so that the AFT output voltage is 2[V].
This frequency is named f(2).
3. IN the graph shown below, maximum and minimum DC voltage are V
18H
and
V18L
, respectively.
