5-7 GSM/GPRS/EDGE Signal Analyzer Verification, Options 40 and 41 Option Verification
5-28 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
35. For an MT821xE with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err RMS
(deg) in section At 1800 MHz, –10 dBm Level, TCH ALL Pattern in Table A-39.
36. Verify that the measured values in Step 34 or Step 35 (or both) are within specifications.
37. On the MG3700A, change the selected pattern to GsmBurst_1slot.
38. 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.
39. 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 38.
Then record the calculated Burst Power error and the displayed value of Freq Error in section
At 1800 MHz, –50 dBm Level, TCH Pattern in Table A-38.
40. For an MT821xE with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err RMS
(deg) in section At 1800 MHz, –50 dBm Level, TCH Pattern in Table A-39.
41. Verify that the measured values in Step 39 or Step 40 (or both) are within specifications.
