7. Set the S412E as follows:
a. Press the Freq main menu key and set the center frequency to 2600.5 MHz.
b. Press the Setup submenu key and set the Bandwidth to 10 MHz.
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 Demodulator, then select Modulation Summary.
8. Record the S412E EVM(rms) reading in Table A-19, “Option 47, Fixed WiMAX Residual EVM”
on page A-17.
9. Verify that the measured EVM is within specification.
10. Adjust the MG3700A level setting to approximately –33 dBm so that the power meter reads
–50.0 dBm ± 0.2 dB.
11. Record the S412E EVM(rms) reading in Table A-19.
12. Verify that the measured EVM is within specification.
13. Record the S412E Freq Error reading in Table A-20, “Option 47, Fixed WiMAX Frequency Error”
on page A-18.
14. Verify that the measured frequency 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 center frequency of the S412E to 3600.5 MHz.
18. Measure the EVM(rms) for both –15 dBm and –50 dBm, record the measured results in Table A-19.
19. Verify that the measured EVM is within specification.
20. Set the cal factor frequency of the power sensor to 5600.5 MHz.
21. Set the MG3700A frequency to 5600.5 MHz.
22. Adjust the MG3700A level setting with the knob so that the power meter reads –15.0 dBm ± 0.2 dBm.
23. Change the center frequency of the S412E to 5600.5 MHz.
24. Record the S412E EVM(rms) reading in Table A-19.
25.
Verify that the measured EVM is within specification.
26. Adjust the MG3700A level setting to approximately –33 dBm so that the power meter reads
