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
Then wait 15 seconds to allow the MS2723B or MS2724B to update its measured results.
4. For MS2723B or MS2724B with Option 42 (CDMA RF Measurements), record the "Channel Power
Value" (in units of watt) into
adjusted "Power Meter Reading" in Step 3. Then record the calculated "Channel Power Error" (in units
of watt) into Table
5. For MS2723B or MS2724B with Option 43 (cdmaOne and CDMA2000 1xRTT Demodulator), record the
displayed Freq Error, Rho, and Tau into
on page A-27.
6. Verify that the measured values in Step
7. On the power meter, press the Sensor key, the Cal Factor soft key, and then the Freq soft 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
10. On the MS2723B or MS2724B, press the Frequency soft key, and enter 870.03 MHz as Center Frequency.
Then wait 15 seconds to allow the MS2723B or MS2724B to update its measured results.
11. For MS2723B or MS2724B with Option 42 (CDMA RF Measurements), record the "Channel Power
Value" (in units of watt) into
adjusted "Power Meter Reading" in Step 9. Then record the calculated "Channel Power Error" (in units
of watt) into Table
12. For MS2723B or MS2724B with Option 43 (cdmaOne and CDMA2000 1xRTT Demodulator), record the
displayed Freq Error, Rho, and Tau into
on page A-27.
