Chapter 5 — Option Verification
Procedure
1. Connect the MA2482D Power Sensor to the power meter and zero the sensor.
2. Set the Power Meter Measurement MODE to True RMS, set Averaging MODE to Moving, and set
Averaging NUMBER to 256.
3. Set the calibration factor frequency of the power sensor to 2600.5 MHz.
4. Connect the equipment as shown in
Channel Power Accuracy (10 MHz Bandwidth and 10 ms Frame Length)
5. Set the MG3700A as follows:
a. Press the yellow 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.
e. Using the Down Arrow key step through the selection list until "mWiMax" is highlighted.
f. Press the Set key.
g. Press the (F6) soft key Return.
h. Press the Set key. The Select Package list box will appear. Again select mWiMax and Set.
i. Another file list will appear. 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 2 dBm. 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 S412E to Mobile WiMax Signal Analyzer mode and preset the unit.
8. Set the S412E as follows:
a. Press the Freq main menu key and set the Center Freq to 2600.5 MHz.
b. Press the Setup submenu 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 submenu key and select RF, then select Power vs. Time.
9. Record the S412E Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column,
2600.5 MHz, –15 dBm row of
Bandwidth and 10 ms Frame
10. Calculate the Channel Power Error by subtracting the S412E "Channel Power (RSSI)" reading from the
power meter reading in
–15 dBm row of
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 S412E Channel Power (RSSI) reading in the 2600.5 MHz, –50 dBm row of
14. Calculate the Channel Power Error by subtracting the S412E "Channel Power (RSSI)" reading from the
power meter reading that was recorded in
15. Verify that the error is within specification.
