1 Adjustment of RF Output Power:

(1) The equipment setup as shown in Figure 1.

(2) Operation of PC adjusts equipment.

(3) Use RF Engineering Tools at PC side.

Select GSM850:

1) Set GSM850 Band.

2) Set ARFCN: 190

3) TX ON.

4) Adjust the power to 32dBm (+1.0dB/-1.0dB, Power control level: PCL=5) and 22.0dBm(+1.0dB/-1.0dB)
by PA DAC value.
5) Repeat 4) for 15 times,and adjust the power level to 30.5, 28.8, 27, 25, 23, 21, 19, 17, 15,

13, 11, 9, 7, 5.

6) Make 16 Ramp-Up/Ramp-Down data from the adjustment value of (5) and (6).

7) Data of 5) and 6) is writen to flash memory.

Select PCS1900:
1) Set PCS1900.

2) Set ARFCN: 512(PCS1900).

3) TX ON.

4) Adjust the power to 29.0 dBm (+1.0dB/-1.0dB, Power control level: PCL=0) and 22.0dBm(+1.0dB/-1.0dB)
by PA DAC value.
5) Repeat 4) for 15 times,and adjust the power level to 27.5, 26, 24, 22, 20, 18, 16, 14, 12,

10, 8, 6, 4, 2, 0.

6) Make 16 Ramp-Up/Ramp-Down data from the adjustment value of (5) and (6).

7) Data of 5) and 6) is writen to flash memory.

2 Adjustment of oscillation frequency of VCXO:

(1) The equipment setup as shown in Figure 1.

(2) Use Crystal AFC Control Tools to Set CapID and AFC DAC value.

(3) Set Band=GSM850,Set ARFCN=190,Set PCL=12.

1) Set AFC DAC=4096,fixed.(Check that Vafc=1.4V).

2) Set CapID=0, and verify that frequency error >>10KHz.

3) Set CapID=63, and verify that frequency error <<-10KHz.

4) If the above 3 items are verified, then change CapID value to make frequency error be

closed to 0 Hz as possible, record this CapID value.

5) Set CapID value got from step 4), then change AFC DAC value to make frequency error

be closed to 0 Hz as possible, record this AFC DAC value.

6) Download the CapID value and AFC DAC value to flash memory.

3 Adjustment of RX Sensitivity:

(1) Select GSM850:

1) Set BCCH level:-85dBm;ARFCN:128.

2) Test sample make a call to connect RF Tester..

3) Set TCH level:-106dBm.

4) Measure BERⅡ error at TCH ARFCN:128, 190，251.

5) Tuen up the RX matching cricuit to make sure BERⅡ<2% at each ARFCN.

(2) Select PCS1900:

1) Set BCCH level:-85dBm;ARFCN:512.

2) Test sample make a call to connect RF Tester..

3) Set TCH level:-106dBm.

4) Measure BERⅡ error at TCH ARFCN:512, 661, 810.

5) Tuen up the RX matching cricuit to make sure BERⅡ<2% at each ARFCN.
