5-10 Fixed WiMAX Signal Analyzer Verification, Options 46 and 47 Option Verification
5-52 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
k. Press the MOD On/Off key and verify that the LED is On. Confirm that the “Playing” indicator is
displaying the moving pattern.
l. Press the Frequency key, then enter 2600.5 MHz.
m. Press the Level key, then enter 2dBm. Turn the output On.
5. Adjust the MG3700A level setting with the knob so that the power meter reads –15.0 dBm ± 0.2 dB.
6. Set the MT821xE to Fixed WiMax Signal Analyzer mode and preset the instrument.
7. Set the MT821xE as follows:
a. Press the Freq main menu key and set the center frequency to 2600.5 MHz.
b. Press the Setup main menu key and set the Bandwidth to 10 MHz.
c. In the Setup menu, verify that the CP Ratio is set to 1/8.
d. Press the Measurements main menu key and press RF Measurements, then press Power vs Time.
8. Record the MT821xE Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column
of Table A-50, “Option 46, Fixed WiMAX Channel Power Accuracy” on page A-37.
9. Calculate the Channel Power Error by subtracting the MT821xE Channel Power (RSSI) reading from the
power meter reading in Step 5. Record the result in the Error column of Table A-50.
10. Verify that the error is within specification.
11. Adjust the MG3700A level setting to approximately –33 dBm so that the power meter reads –50.0 dBm.
12. Record the MT821xE Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column
of Table A-50.
13. Calculate the Channel Power Error by subtracting the MT821xE Channel Power (RSSI) reading from the
power meter reading in
Step 11. Record the result in the Error column of Table A-50.
14. Verify that the error is within specification.
15. Set the calibration factor frequency of the power sensor to 3600.5 MHz.
16. Set the MG3700A frequency to 3600.5 MHz.
17. Change the MT821xE center frequency to 3600.5 MHz.
18. Measure the Channel Power (RSSI) for both –15 dBm and –50 dBm and then record the measured results
and calculated errors in Table A-50.
19. Verify that the errors are within specification.
20. Set the calibration factor frequency of the power sensor to 5600.5 MHz.
21. Set the MG3700A frequency to 5600.5 MHz.
22. Change the MT821xE center frequency to 5600.5 MHz.
23. Repeat Step 18 and Step 19.
