Hsdpa Rf Channel Power Accuracy And Aclr Verification (Option 44) - Anritsu Spectrum Master MS2722C Maintenance Manual

Chapter 3 — Options Verification 3-5 Option 44, 45, and/or 65 WCDMA/HSDPA Signal Analyzer Verification
ACLR Error at –10 or 10 MHz Offset = 10 LOG
30. Record the calculated results into the corresponding cells in the "Calculated ACLR Error" column in
Table A-94 and verify that it is within specification.
31. Calculate the ACLR Error at –5 MHz Offset and +5 MHz Offset by using the following formula:
ACLR Error at –5 or 5 MHz Offset = 10 LOG
32. Record the calculated results into the corresponding cells in
specification.
33. Repeat Step 19 through

HSDPA RF Channel Power Accuracy and ACLR Verification (Option 44)

The tests in this section can be used to verify the RF Channel Power Accuracy and Adjacent Channel Leakage
Ratio (ACLR) Accuracy for HSDPA signals in WCDMA/HSDPA Signal Analyzer Mode.
Procedure
1. Turn on the MG3700A Vector Signal Generator and the ML2438A power meter.
2. Connect the power sensor to the power meter and zero the sensor.
3. Connect the MG3700A, splitter, attenuator, power meter, and sensor according to
4. Press the On/Off key to turn on the MS272xC, and wait until the measurement display appears. Then
press the Shift key, and then press the Mode (9) key to activate the mode selection menu.
5. Use the Up/Down arrow keys to select WCDMA, and press the Enter key.
6. Press the Shift key, the Preset (1) key, and then the Preset submenu key.
7. On the MG3700A, press the Preset key (Yellow key on the upper-left corner).
8. Press the Down Arrow key to select Yes.
9. Press the Set key (Note that two Set keys are available, and they both do the same thing).
10. Press the (F1) submenu key to select "Load File to Memory"
11. Press the (F1) submenu key again to select "Select Package"
12. Using the Down Arrow key, step through the selection list until the WCDMA(BS Tx test) option is
highlighted.
13. Press the Set key.
14. Press the (F6) submenu key, Return.
15. Press the Set key.
16. Using the Down Arrow key, step through the selection list until the TestModel_5_8HSPDSCH 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, then enter 2680.5, and press the MHz key.
20. Press the Level key, then enter –2, and press the dBm key.
21. Use the knob to adjust the power meter to read –20 dBm, and record the Power Meter reading in the
"Power Meter Reading" column of
on page A-43.
22. On the MS272xC, press the Center Freq submenu key, enter 2680.5, and then press the Enter key.
23. Press the Measurements main menu key, then the RF Measurement submenu key, and press ACLR.
