4. Set the oscillation frequency to 549.5 MHz, and check that the voltmeter

reading is 17

1 V.

5. Measure the output at J405 with the spectrum analyzer, and check that both

frequencies are within the range of –16

4 dBm and that they vary

smoothly as the frequency is changed from its bottom to its top limit. Do not
connect anything to J405 after completing this check.

6. Connect the network analyzer output to J404 and the input to J402. Check

that there is no solder touching the cut land before testing, and be sure to
remove solder if any is touching on the test pad.

7. Set the oscillation frequency to 549.5 MHz, and check that the deviation in

the amplitude characteristic at 479.5

20 MHz is 0.5 dB or less.

8. Set the oscillation frequency to 409.5 MHz, and adjust C410 so the devia-

tion in the amplitude characteristic at 479.5

20 MHz is 0.5 dB or less.

9. Connect the network analyzer output to J401 and the input to J402. Apply

solder to the cut land so as to produce a short.

10. Set the oscillation frequency to 549.5 MHz, and adjust C408 and C409 so the

deviation in the amplitude characteristic at 479.5

20 MHz is 0.5 dB or less.

11. Set the oscillation frequency to 409.5 MHz, and adjust C408 and C409, and

adjust as in step 10.

12. Repeat steps 10 and 11 two or three times. Adjust so the difference be-

tween the two levels is minimized.

13. Check that the conversion gain at 479.5 MHz is 4

1 dB.

14. With the PLL unlocked, check that JL01 pin 9 is high.
