5-15 EVDO Signal Analyzer Verification, Options 62 and 63 Option Verification
5-74 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
7. For an MT821xE with Option 62 (EVDO RF Measurements), subtract the displayed Channel Power value
from the power meter reading in Step 5. Then record the calculated Channel Power error to the
At 1930.05 MHz, 0 dBm Level, 38.4kps QPSK Modulation section of Table A-66 on page A-43.
8. For an MT821xE with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot, and
Tau to the At 1930.05 MHz, 0 dBm Level, 38.4kps QPSK Modulation section of Table A-67
on page A-44.
9. Verify that the measured values in Step 7 and Step 8 are within specifications.
16-QAM 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. The power sensor calibration
factor frequency should still be at 1930 MHz, and the MG3700A frequency and MT821xE Center
Frequency should still be at 1930.05 MHz.
2. On the MG3700A, change the selected pattern to FWD_2457_6KBPS_1SLOT.
3. Adjust the MG3700A output so that the power meter reads –50 dBm ± 0.2 dB.
4. Then wait 15 seconds to allow the MT821xE to update its measured results.
5. For an MT821xE with Option 62 (EVDO RF Measurements), subtract the displayed Channel Power value
from the power meter reading in Step 3. Then record the calculated Channel Power error in the
At 1930.05 MHz, –50 dBm Level, 2457.6kps 16-QAM Modulation section of Table A-66.
6. For an MT821xE with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot, and
Tau in the At 1930.05 MHz, –50 dBm Level, 2457.6kps 16-QAM Modulation section of Table A-67.
7. Verify that the measured values in Step 5 and Step 6 are within specifications.
