3-9 Option 884, CDMA Signal Analyzer Verification Chapter 3 — Options Verification
3-36 PN: 10580-00342 Rev. D MS2720T MM
22. Set the MG3700A Frequency to 1930.05 MHz.
23. Adjust the MG3700A output so that the power meter reads –30 dBm ± 0.2 dB. Record the adjusted
“Power Meter Reading” into Table A-96, “RF Measurements, At 1930.05 MHz, –30 dBm Level,
cdmaOne” on page A-49.
24. On the MS2720T, press the Freq main menu key, and enter 1930.05 MHz as Center Freq. Then wait
15 seconds to allow the MS2720T to update its measured results.
25. Record the “Channel Power Value” into Table A-96, and subtract the displayed “Channel Power Value”
from the adjusted “Power Meter Reading” in Step 23. Then record the calculated “Channel Power Error”
into Table A-96.
26. Record the displayed Freq Error, Rho, and Tau into Table A-100, “Demodulation, At 1930.05 MHz,
–30 dBm Level, cdmaOne” on page A-50.
27. Verify that the measured values in Step 25 and Step 26 are within specifications.
CDMA2000 Channel Power, Frequency Error, Rho and Tau Tests
Test Procedure
1. Verify that the equipment settings are unchanged from the previous test.
2. On the MG3700A, change the selected pattern to “FWD_RC3-5_9channel”.
3. Adjust the level of the MG3700A so that the power meter reads –30 dBm ± 0.2 dB. Record the adjusted
“Power Meter Reading” into Table A-97, “RF Measurements, At 1930.05, –30 dBm Level, CDMA2000”
on page A-49. Then wait 15 seconds to allow the MS2720Tto update its measured results.
4. Record the “Channel Power Value” into Table A-97, and subtract the displayed “Channel Power Value”
from the adjusted “Power Meter Reading” in Step 3. Then record the calculated “Channel Power Error”
into Table A-97.
5. Record the displayed Freq Error, Rho and Tau into Table A-101, “Demodulation, At 1930.05 MHz,
–30 dBm Level, CDMA2000” on page A-50.
6. Verify that the measured values in Step 4 and Step 5 are within specifications.
7. On the power meter, press the Sensor key, the Cal Factor submenu key, and then the Freq submenu key.
Use the keypad to enter 870.03 MHz as the input signal frequency, which sets the power meter to the
proper power sensor calibration factor. Press the System key to display the power reading.
8. Set the MG3700A Frequency to 870.03 MHz.
9. Adjust the MG3700A output so that the power meter reads –30 dBm ± 0.2 dB. Record the adjusted
“Power Meter Reading” into Table A-98, “RF Measurements, At 870.03 MHz, –30 dBm Level,
CDMA2000” on page A-49.
10. On the MS2720T, press the Freq main menu key, and enter 870.03 MHz as Center Freq. Then wait
15 seconds to allow the MS2720T to update its measured results.
11. Record the “Channel Power Value” into Table A-98, and subtract the displayed “Channel Power Value”
from the adjusted “Power Meter Reading” in Step 9. Then record the calculated “Channel Power Error”
into Table A-98.
12. Record the displayed Freq Error, Rho and Tau into Table A-102, “Demodulation, At 870.03 MHz,
–30 dBm Level, CDMA2000” on page A-50.
13. Verify that the measured values in
Step 11 and Step 12 are within specifications.
