1. Increase the frequency of SG9 until the VCO is out of locked-oscillation.
2. Decrease the frequency of SG9 and measure the frequency fU when the
VCO locks.
CL - U = fU - 58.75 (MHz)
8. Capture range: CL - L
1. Decrease the frequency of SG9 until the VCO is out of locked-oscillation.
2. Increase the frequency of SG9 and measure the frequency fL when the
VCO locks.
CL - L = 58.75 - fL (MHz)

10. AFT sensitivity µ, Maximum AFT voltage V2H, Minimum AFT voltage V2L
1. Input SG10 into VIF IN, and set the frequency of SG10 so that the
voltage of AFT output TP2 is 3V . This frequency is named f(3).
2. Set the frequency of SG10 so that the AFT output voltage is 2V.
