e. Using the Down Arrow key, step through the selection list until "WiMAX" is highlighted.
f. Press the Set key.
g. Press the (F6) soft key, Return.
h. Press the Set key. The "Select Package" list box is displayed. Again select "WiMAX" and press Set.
i. Another file list is displayed. Select (highlight) "Mx10g32".
j. Press the Set key.
k. Press the MOD On/Off key and verify that the LED is On. Ensure 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 2 dBm. 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, and
record the actual power meter reading into the "Input Power Reading" column of
WiMAX Channel Power Accuracy Adjusted MG3700A Level Settings" on page
6. Set the MS2723B or MS2724B to Fixed WiMAX Signal Analyzer Mode and preset the instrument.
7. Set the MS2723B or MS2724B as follows:
a. Press the Freq soft key and set the Center Freq to 2600.5 MHz.
b. Press the Setup soft key and set the Bandwidth to 10 MHz.
c. Press the CP Ratio soft key (under the Setup soft key) and set the CP Ratio to 1/32.
d. Press the Measurements soft key and press RF, then press Power vs. Time.
8. Record the MS2723B or MS2724B Channel Power (RSSI) reading into the "Measured Channel
Power (RSSI)" column in
9. Calculate the Channel Power Error by subtracting the MS2723B or MS2724B "Measured Channel
Power (RSSI)" reading from the power meter reading in Step
"Error" column in
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,
and record the actual power meter reading into the "Input Power Reading" column of
12. Record the MS2723B or MS2724B Channel Power (RSSI) reading into the "Measured Channel
Power (RSSI)" column in
13. Calculate the Channel Power Error by subtracting the MS2723B or MS2724B "Measured Channel
Power (RSSI)" reading from the power meter reading in Step
"Error" column in
14. Verify that the error is within specification.
15. Set the calibration factor frequency of the power sensor to 3600.5 MHz.
16. Set MG3700A Frequency to 3600.5 MHz.
17. Change the Center Frequency of MS2723B or MS2724B to 3600.5 MHz.
18. Measure the Channel Power (RSSI) for both –15 dBm and –50 dBm (recording actual values into
Table A-82), and then record the measured results and the calculated errors into
19. Verify that the errors are within specification.
20. Set the calibration factor frequency of the power sensor to 5600.5 MHz.
21. Set MG3700A Frequency to 5600.5 MHz.
22. Change the Center Frequency of the MS2723B or MS2724B to 5600.5 MHz.
23. Repeat Step 18 and Step 19.
