3-8 CDMA Signal Analyzer (Options 42 and 43) Verification Performance Verification 2
3-42 PN: 10580-00177 Rev. D MS2721B MM
cdmaOne Channel Power, Frequency Error, Rho, and Tau Tests
Test Procedure:
1. On the MG3700A, press the Preset key (Yellow key on the upper left-hand side).
2. Press the Down Arrow key or turn the knob to select Yes.
3. Press the Set key (Note that two Set keys are available, and they both do the same thing).
4. Press the (F1) soft key to select "Load File to Memory"
5. Press the (F1) soft key again to select "Select Package"
6. Using the Down Arrow key step through the selection list until the "CDMA2000" option is highlighted.
7. Press the Set key.
8. Press the (F6) soft key, "Return"
9. Press the Set key. The "Select Package" box appears. Use the rotary knob to highlight "CDMA2000" and
press the Set key to select.
10. Another File List appears. Use the rotary knob to select "FWD_RC1-2_9channel" and press the Set key to
select.
11. Press the MOD On/Off key to turn on the Modulation LED and verify that the "Playing" indicator in the
center of the LCD is flashing.
12. Press the Frequency key, and enter 870.03 MHz.
13. Press the Level key, enter –30, and press the dBm soft key.
14. Adjust the MG3700A output so that the power meter reads –30 dBm ± 0.2 dB. Record the exact value in
Table A-92, “Channel Power Error at 870.03 MHz, –30 dBm Level, cdmaOne, Option 42” on page A-32.
15. On the MS2721B, press the Freq function hard key and enter 870.03 MHz as Center Frequency.
16. Press the Measurements function hard key and press CDMA Summary (a red dot appears on the label).
17. Press the Setup function hard key and press PN Setup. Then change PN Trigger to Ext by pressing the
PN Trigger soft key twice. Then wait 15 seconds to allow the MS2721B to update its measured results.
18. For an MS2721B with Option 42 (CDMA RF Measurements), record the displayed Channel Power value
in Table A-92 and subtract it from the power meter reading (set in Step 14). Then record the calculated
Channel Power error in Table A-92.
Channel Power Error = Set Channel Power – Displayed Channel Power
19. For an MS2721B with Option 43 (cdmaOne and CDMA2000 1xRTT Demodulator), record the displayed
Freq Error, Rho, and Tau in Table A-96, “At 870.03 MHz, –30 dBm Level, cdmaOne, Option 43”
on page A-33.
20. Verify that the measured values in Step 18 and Step 19 are within specifications.
21. On the power meter, press the Sensor key, the Cal Factor soft key, and then the Freq soft key. Use the
keypad to enter 1930 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.
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 exact value in
Table A-93, “Channel Power Error at 1930.05 MHz, –30 dBm Level, cdmaOne, Option 42” on page A-32.
24. On the MS2721B, press the Freq function hard key and enter 1930.05 MHz as Center Frequency. Then
wait 15 seconds to allow the MS2721B to update its measured results.
25. For an MS2721B with Option 42 (CDMA RF Measurements), record the displayed Channel Power value
in Table A-93 and subtract it from the power meter reading (set in Step 23). Then record the calculated
Channel Power error in Table A-93.
Channel Power Error = Set Channel Power – Displayed Channel Power
