Option Verification 5-7 GSM/GPRS/EDGE Signal Analyzer Verification, Options 40 and 41
MT8212E and MT8213E MM PN: 10580-00255 Rev. J 5-27
10. Press the (F1) soft key again to select Select Package.
11. Using the Down Arrow key, step through the selection list until the “GSM” option is highlighted.
12. Press the Set key.
13. Press the F6 (Return) soft key.
14. Press the Set key. The Select Package box appears. Use the rotary knob to highlight GSM and press the
Set key to select.
15. Another File List appears. Use the rotary knob to select GsmBurst_1slot and press the Set key to select.
16. Press the MOD On/Off key to turn the Modulation LED On and verify that the “Playing” indicator in the
center of the LCD is flashing.
17. Press the Frequency key and enter 850 MHz.
18. Press the Level key, enter –10, and press the dBm submenu key.
19. Adjust the MG3700A output so that the power meter reads –10 dBm ± 0.2 dB.
20. On the MT821xE, press the Freq main menu key and set 850 MHz as the Center Frequency.
21. Press the Measurements main menu key and press GSM/EDGE Summary (a red dot appears on the label
when active).
22. For an MT821xE with Option 40 (GSM/GPRS/EDGE RF Measurements), take the displayed Burst Power
value and subtract an offset of 9.2 dB. Then subtract this value from the power meter reading in Step 19.
Then record the calculated Burst Power error and the displayed value of Freq Error in section
At 850 MHz, –10 dBm Level, TCH Pattern in Table A-38, “Option 40 GSM/GPRS/EDGE RF
Measurements” on page A-30.
23. For an MT821xE with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err RMS
(deg) in section At850MHz, –10dBm Level, TCH Pattern
in Table A-39, “Option 41
GSM/GPRS/EDGE Demodulator” on page A-31.
24. Verify that the measured value in Step 22 or Step 23 (or both) are within specifications.
25. On the MG3700A, change the selected signal pattern to GsmBurst_8slot.
26. Adjust the Level of the MG3700A so that the power meter reads –50 dBm ± 0.2 dB. Then wait 15 seconds
to allow the MT821xE to update its measured results.
27. For an MT821xE with Option 40 (GSM/GPRS/EDGE RF Measurements), take the displayed Burst Power
value and subtract an offset of 0.2 dB. Then subtract this value from the power meter reading in Step 26.
Then record the calculated Burst Power error and the displayed value of Freq Error in section
At 850 MHz, –50 dBm Level, TCH ALL Pattern in Table A-38.
28. For an MT821xE with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err RMS
(deg) in section At850MHz, –50dBm Level, TCH ALL Pattern in Table A-39.
29. Verify that the measured value in Step 27 or Step 28 (or both) are within specifications.
30. Change the frequency of MG3700A to 1800 MHz.
31. On the power meter, press the Sensor key, the Cal Factor soft key, and then the FREQ soft key. Use the
keypad to enter 1800 MHz as the input signal frequency, which sets the power meter to the proper power
sensor calibration factor. Press the System key to display the power reading.
32. Adjust the level of the MG3700A so that the power meter reads –10 dBm ± 0.2 dB.
33. On the MT821xE, set the Center Frequency to 1800 MHz. Then wait 15 seconds to allow the MT821xE to
update its measured results.
34. For an MT821xE with Option 40 (GSM/GPRS/EDGE RF Measurements), take the displayed Burst Power
value and subtract an offset of 0.2 dB. Then subtract this value from the power meter reading in Step 32.
Then record the calculated Burst Power error and the displayed value of Freq Error in section
At 1800 MHz, –10 dBm Level, TCH ALL Pattern in Table A-38.
