Option Verification 5-9 WCDMA/HSDPA Signal Analyzer Verification, Options 44, 45, 65,
MT8212E and MT8213E MM PN: 10580-00255 Rev. J 5-37
9. Press the Set key.
10. Press the (F1) soft key to select Load File to Memory.
11. Press the (F1) soft key again to select Select Package.
12. Using the Down Arrow key, step through the selection list until the W-CDMA(BS Tx test) option is
highlighted.
13. Press the Set key.
14. Press the F6 (Return) soft key.
15. Press the Set key. The Select Package list box appears. Again select W-CDMA(BS Tx test) and then
press the Set key.
16. Another file list appears. Using the Down Arrow key, step through the selection list until the
TestModel_1_16DPCH option is highlighted.
17. Press the Set key.
18. Press the MOD On/Off key and verify that the Modulation indicator on the display is On.
19. Press the Frequency key, enter 881.5 MHz, then press the MHz submenu key.
20. Press the Level key, enter –28, and press the dBm submenu key.
21. Use the knob to adjust the power level so that Sensor B reads +10 dBm.
22. Set the MN63A attenuator to 0dB.
23. Record the Sensor A reading (PMA.10) in Table A-42, “Option 44, Sensor A and B Reading Components
Characterization Table” on page A-34. This should be approximately –20 dBm.
24. Record the Sensor B reading (PMB.10) in Table A-42.
25.
Calculate Delta 1, which is the error of the coupler output port deviation from ideal +10 dBm by using the
following formula:
Delta 1 (dBm) = (10 dBm – PMB.10)
26. Record the Delta 1 value in Table A-42.
27. Calculate the accurate value of Sensor A reading for coupler port output of +10 dBm (PMA.10C) ny using
the following formula:
PMA.10C = PMA.10 + Δ1
28. Record the calculated value in Table A-42.
29. Set the MN63A attenuator to 10 dB and record the Sensor A reading (PMA.20) in Table A-42.
30. Calculate the accurate attenuation value using the following formula:
ATT.10 = (PMA.10 – PMA.20)
31. Record the calculated value in Table A-42.
32. Turn Off the RF output of the MG3700A.
33. Disconnect the coupler from Sensor B and connect the coupler to the MT821xE SPA RF In connector.
Refer to Figure 5-9
Note The MG3700A has two Set keys, and they both have the same function.
