c. Press the CP Ratio submenu key (under the Setup submenu key) and set the CP Ratio to 1/32.
d. Press the Measurements submenu key and select RF, then select Power vs. Time.
8. Record the S412E Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column of
Table A-18, "Option 46, Fixed WiMAX Channel Power
9. Calculate the Channel Power Error by subtracting the S412E Channel Power (RSSI) reading from the
power meter reading 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.
12. Record the S412E Channel Power (RSSI) reading in the Measured Channel Power (RSSI) column of
Table A-18.
13. Calculate the Channel Power Error by subtracting the S412E Channel Power (RSSI) reading from the
power meter reading in
14. Verify that the error is within specification.
15. Set the cal factor frequency of the power sensor to 3600.5 MHz.
16. Set the MG3700A frequency to 3600.5 MHz.
17. Change the S412E center frequency to 3600.5 MHz.
18. Measure the Channel Power (RSSI) for both –15 and –50 dBm and then record the measured result and
calculated error in
