CL-U Capture Range

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-L Capture Range

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.

AFT Minimum Voltage

1. Input SG10 into VIF IN, and set the frequency of SG 10 so that the voltage of AFT output TP19 is 5 V. This

frequency is named f (3).

2. Set the frequency of SG10 so that the AFT output voltage is 4 V. This frequency is named f (2).

3. In the graph, maximum and minimum DC voltage are V

19H

and V
