Option Verification 5-18 Mobile WiMAX Signal Analyzer Verification, Options 66 and 67
MT8212E and MT8213E MM PN: 10580-00255 Rev. J 5-95
e. Using the Down Arrow key, step through the selection list until “mWiMax” is highlighted.
f. Press the Set key.
g. Press the F6 (Return) soft key.
h. Press the Set key. The Select Package list box appears. Again select mWiMax and press Set.
i. Another file list appears. Select (highlight) 10m1024g8_0_10_cap.
j. Press the Set key.
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.
6. Adjust the MG3700A level setting with the knob so that the power meter reads –15.0 dBm ± 0.2 dB.
7. Set the MT821xE to Mobile WiMax Signal Analyzer mode and preset the instrument.
8. Set the MT821xE as follows:
a. Press the Freq main menu key and set the Center Freq to 2600.5 MHz.
b. Press the Setup main menu key and set the Bandwidth to 10 MHz.
c. Press the Frame Length submenu key and set the Frame Length to 10 ms.
d. Press the Measurements main menu key and press RF Measurements, then press Power vs Time.
9. Record the MT821xE Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column,
2600.5 MHz, –15 dBm
row of Table A-85, “Option 66, Mobile WiMAX Channel Power Accuracy (10 MHz
Bandwidth and 10 ms Frame Length)”.
10. Calculate the Channel Power Error by subtracting the MT821xE “Channel Power (RSSI)” reading from
the power meter reading in Step 6. Record the result into the test record in the Error column,
2600.5 MHz, –15 dBm row of Table A-85.
11. Verify that the error is within specification.
12. Adjust the MG3700A level setting to approximately –33 dBm so that the power meter
reads –50.0 dBm ± 0.2 dB.
13. Record the MT821xE Channel Power (RSSI) reading in the 2600.5 MHz, –50 dBm row of Table A-85.
14. Calculate the Channel Power Error by subtracting the MT821xE “Channel Power (RSSI)” reading from
the power meter reading that was recorded in Step 13. Record the result in Table A-85.
15. Verify that the error is within specification.
16. Set the calibration factor frequency of the power sensor to 3600.5 MHz.
17. Set the MG3700A frequency to 3600.5 MHz.
18. Change the MT821xE center frequency to 3600.5 MHz.
19. Measure the Channel Power (RSSI) for both –15 dBm and – 50 dBm and then record the measured result
and calculated error in Table A-85.
20. Verify that the error is within specification.
Channel Power Accuracy (5 MHz Bandwidth and 5 ms Frame Length)
21. Set the MG3700A as follows:
a. Press the yellow Preset button (answer Yes to the question).
b. Press the Set key
c. Press the (F1) soft key to select Load File to Memory.
d. Press the (F1) soft key again to select Select Package.
