3-12 EVDO Signal Analyzer Option Verification (Options 62 and 63) Performance Verification 2
3-72 PN: 10580-00177 Rev. D MS2721B MM
QPSK Modulation Channel Power, Frequency Error, Rho, and Tau Tests
Test Procedure:
1. Ensure 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 0 dBm ± 0.2 dB, and record the actual value
(as shown on the power meter) into Table A-116, “EVDO Channel Power Error at 1930.05 MHz, 0 dBm
Level, 38.4 kps QPSK Modulation, Option 62” on page A-37.
6. On the MS2721B, press the Frequency function hard key and enter 1930.05 MHz as Center Frequency.
Then wait 15 seconds to allow the MS2721B to update its measured results.
7. Record the displayed MS2721B Channel Power value in Table A-116.
8. For an MS2721B 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 in
Table A-116.
9. For an MS2721B with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot, and
Tau in Table A-121, “EVDO Demodulator At 1930.05 MHz, 0 dBm Level, 38.4 kps QPSK Modulation,
Option 63” on page A-39.
10. Verify that the measured values in Step 8 and Step 9 are within specifications.
16-QAM Modulation Channel Power, Frequency Error, Rho, and Tau Tests
Test Procedure:
1. Ensure that the equipment settings are unchanged from the previous test. The power sensor Cal Factor
frequency should still be at 1930 MHz. The MG3700A frequency and the MS2721B 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, and record the actual
value (as shown on the power meter) into Table A-117, “EVDO Channel Power Error at 1930.05 MHz,
–50 dBm Level, 2457.6 kps 16-QAM Modulation, Option 62” on page A-38.
4. Then wait 15 seconds to allow the MS2721B to update its measured results.
5. Record the displayed MS2721B Channel Power value in Table A-117.
6. For an MS2721B 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
Table A-117.
7. For an MS2721B with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot, and
Tau in Table A-122, “EVDO Demodulator At 1930.05 MHz, –50 dBm Level, 2457.6 kps 16-QAM
Modulation, Option 63” on page A-39.
8. Verify that the measured values in Step 6 and Step 7 are within specifications.
