3-12 Option 885, Mobile WiMAX Signal Analyzer Verification Chapter 3 — Options Verification
3-48 PN: 10580-00342 Rev. D MS2720T MM
7. Verify that the error is within specification.
8. Adjust the MG3700A Level setting to approximately –33 dBm so that the power meter reads
–50.0 dBm ± 0.2 dB, and record the actual value as shown on the power meter into Table A-122, “RF
Measurements, Mobile WiMAX Channel Power Accuracy Power Error (2600.5 MHz and –50.0 dBm)”
on page A-57.
9. Record the “MS2720T Reading”, the displayed Channel Power (RSSI) value, into Table A-122.
10. Calculate the Channel Power Error by subtracting the “MS2720T Reading” of Channel Power (RSSI)
from the “Power Meter Reading” in Step 8. Record the “Calculated Channel Power Error” into
Table A-122.
11. Verify that the error is within specification.
12. Set the calibration factor frequency of the power sensor to 3600.5 MHz.
13. Set MG3700A Frequency to 3600.5 MHz.
14. Change the Center Frequency of MS2720T to 3600.5 MHz.
15. Measure the Channel Power (RSSI) for both –15 dBm and –50 dBm, and then record the measured
results and calculated errors into Table A-123, “RF Measurements, Mobile WiMAX Channel Power
Accuracy Power Error (3600.5 MHz and –15.0 dBm)” on page A-57 and Table A-124, “RF Measurements,
Mobile WiMAX Channel Power Accuracy Power Error (3600.5 MHz and –50.0 dBm)” on page A-57.
16. Verify that the errors are within specification.
