Performance Verification 2 3-7 GSM/GPRS/EDGE Signal Analyzer (Options 40 and 41) Verification
MS2721B MM PN: 10580-00177 Rev. D 3-37
27. Adjust the level of the MG3700A so that the power meter reads –10 dBm ± 0.2 dB.
28. On the MS2721B, set the Center Freq to 1800 MHz. Then wait 15 seconds to allow the MS2721B to
update its measured results.
29. For an MS2721B with Option 40 (GSM/GPRS/EDGE RF Measurements), subtract the displayed Burst
Power value from the power meter reading in Step 27. Then record the calculated Burst Power error and
the displayed value of Freq Error in Table A-78, “At 1800 MHz, –10 dBm Level, TCH ALL Pattern,
Option 40” on page A-29.
30. For an MS2721B with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err
RMS (deg) in Table A-86, “Phase Err RMS (Deg) at 1800 MHz, –10 dBm Level, TCH ALL Pattern,
Option 41” on page A-31.
31. Verify that the measured values in Step 29 and Step 30 are within specifications.
32. On the MG3700A, change the selected pattern to "GsmBurst_1slot".
33. Adjust the level of the MG3700A so that the power meter reads –50 dBm ± 0.2 dB. Then wait 15 seconds
to allow the MS2721B to update its measured results.
34. For an MS2721B with Option 40 (GSM/GPRS/EDGE RF Measurements), subtract the displayed Burst
Power value from the power meter reading in Step 33. Then record the calculated Burst Power error and
the displayed value of Freq Error Table A-79, “At 1800 MHz, –50 dBm Level, TCH Pattern, Option 40”
on page A-29.
35. For an MS2721B with Option 41 (GSM/GPRS/EDGE Demodulator), record the displayed Phase Err RMS
(deg) in Table A-87, “Phase Err RMS (Deg) at 1800 MHz, –50 dBm Level, TCH Pattern, Option 41”
on page A-31.
36. Verify that the measured values in Step 34 and Step 35 are within specifications.
