5-14 TD-SCDMA Signal Analyzer Verification, Options 60 and 61 Option Verification
5-70 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
Procedure
1. Calibrate the power sensor prior to connecting to the power splitter.
2. Connect the equipment as shown in Figure 5-12.
3. On the power meter, press the Sensor key, the Cal Factor soft key, and then the FREQ soft key. Use the
keypad to enter 2010 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.
4. Set the power meter to Averaging, Moving and 256 samples.
5. Set the MT821xE to TD-SCDMA Signal Analyzer mode and preset the instrument.
6. On the MG3700A, press the Preset key (yellow key on the upper left-hand side).
7. Press the Down Arrow key or turn the knob to select Yes.
8. Press the Set key.
9. Press the F1 submenu key to select Load File to Memory.
10. Press the F1 submenu key again to select Select Package.
11. Using the Down Arrow key, step through the selection list until the TD-SCDMA(MX370001A) 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
TD-SCDMA(MX370001A) and press the Set key to select.
15. Another file list appears. Use the rotary knob to select rmc-P-CCPCH_bs_dl 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, enter 2010 MHz.
18. Press the Level key, enter –20 and press the dBm submenu key.
19. Adjust the MG3700A output so that the power meter reads –45 dBm ± 0.5 dB.
20. On the MT821xE, press the Frequency main menu key and enter 2010 MHz as center frequency.
21. Press the Measurements main menu key and press TD-SCDMA Summary (a red dot will appear on the
label).
22. Press the Setup main menu key and press Trigger. Then change Trigger Type to Ext by pressing the Trigger
Type submenu key twice. Then wait 15 seconds to allow the MT821xE to update its measured results.
23. For an MT821xE with Option 60 (TD-SCDMA RF Measurements), subtract the displayed Channel Power
value from the power meter reading in Step 19. Then record the calculated Channel Power Error in
Table A-65, “Option 60, 61, TD-SCDMA Verification (at 2010 MHz, –45 dBm Level, TD-SCDMA)”
on page A-42.
24. For an MT821xE with Option 61 (TD-SCDMA Demodulator), record the displayed Freq error and Tau
values in Table A-65.
25. Verify that the measured values in Step 23 and Step 24 are within specifications.
Note The TD-SCDMA pattern requires a Waveform Data license MX370001A, which must be purchased.
Note The MG3700A has two Set keys, and they both have the same function.
