9. Record the MS272xC EVM (rms) reading into the “EVM (rms)” column in Table A-101, “Option 47,
Fixed WiMAX Residual EVM” on page A-46.
10. Verify that the measured EVM 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 MS272xC EVM (rms) reading into the “EVM (rms)” column in Table A-101.
13. Verify that the measured EVM is within specification.
14. Record the MS272xC Frequency Error reading into Table A-102, “Option 47, Fixed WiMAX Frequency
Error” on page A-46.
15. Verify that the measured Frequency Error is within specification.
16. Set the calibration factor frequency of the power sensor to 3600.5 MHz.
17. Set MG3700A frequency to 3600.5 MHz.
18. Change the center frequency of MS272xC to 3600.5 MHz.
19. Measure the EVM (rms) for both –15 dBm and –50 dBm, and then record the measured results into
Table A-101.
20. Verify that the measured EVM is within specification.
21. Set the calibration factor frequency of the power sensor to 5600.5 MHz.
22. Set MG3700A Frequency to 5600.5 MHz.
23. Adjust the MG3700A Level setting with the knob so that the power meter reads –15.0 dBm ± 0.2 dB.
24. Change the center frequency of the MS272xC to 5600.5 MHz.
25. Record the MS272xC EVM (rms) reading into the “EVM (rms)” column in Table A-101.
26. Verify that the measured EVM is within specification.
27. Adjust the MG3700A Level setting to approximately –33 dBm so that the power meter reads –50.0 dBm.
28. Record the MS272xC EVM (rms) reading into the “EVM (rms)” column in Table A-101.
