8. Press the (F1) soft key to select Load File to Memory.
9. Press the (F1) soft key again to select Select Package.
10. Using the Down Arrow key, step through the selection list until the CDMA2000_1xEV-DO option is
highlighted.
11. Press the Set key.
12. Press the F6 (Return) soft key.
13. Press the Set key. The Select Package box appears. Use the rotary knob to highlight CDMA2000_1xEVDO
and press the Set key to select.
14. Another File List appears. Use the rotary knob to select FWD_921_6KBPS_2SLOT and press the Set key
to select.
15. Press the MOD On/Off key to turn the Modulation LED On, and verify that the “Playing” indicator in
the center of the LCD is flashing.
16. Press the Frequency key, enter 870.03 MHz.
17. Press the Level key, enter –40 and press the dBm submenu key.
18. Adjust the MG3700A output so that the power meter reads –50 dBm ± 0.2 dB.
19. On the MT821xE, press the Frequency main menu key and set 870.03 MHz as Center Frequency.
20. Press the Measurements main menu key and press EVDO Summary (red dot will appear on the label).
21. Press the Setup main menu key and press PN Setup. Then change PN Trigger to Ext by pressing the
PN Trigger submenu key twice. Then wait 15 seconds to allow the MT821xE to update its measured
results.
22.
For an MT821xE with Option 62 (EVDO RF Measurements), subtract the displayed Channel Power
value from the power meter reading in Step 18. Then record the calculated Channel Power Error in the
At 870.03 MHz, 50 dBm Level, 921.6kps 8-PSK Modulation section of Table A-66, “Option 62,
EVDO RF Measurements” on page A-43.
23. For an MT821xE with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot, and
Tau in the 870.03 MHz, 50 dBm Level, 921.6kps 8-PSK Modulation section of Table A-67,
“Option 63, EVDO Demodulator” on page A-44.
24. Verify that the measured values in Step 22 and Step 23 are within specifications.
QPSK Modulation Channel Power, Frequency Error, Rho, and Tau Verification
The tests in this section verify the function of the optional EVDO Signal Analyzer in Model MT821xE
Cell Master.
Procedure
1. Confirm that the equipment settings are unchanged from the previous test.
2. On the MG3700A, change the selected pattern to “FWD_38_4KBPS_16SLOT”.
3. 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.
4. Set the MG3700A frequency to 1930.05 MHz.
5. Adjust the MG3700A output so that the power meter reads 0dBm±0.2dB.
6. On the MT821xE, press the Frequency main menu key and set 1930.05 MHz as Center Frequency. Then
wait 15 seconds to allow the MT821xE to update its measured results.
