5-8 CDMA Signal Analyzer Verification, Options 42 and 43 Option Verification
5-34 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
CDMA2000 Channel Power, Frequency Error, Rho, and Tau Verification
(Option 42 and 43)
The tests in this section verify the function of the optional CDMA Signal Analyzer in Model MT821xE
Cell Master.
Equipment Required
• Anritsu MG3700A Vector Signal Generator
• Anritsu ML2438A Power Meter
• Anritsu MA2482D Power Sensor
• Anritsu 34NN50A Adapter
• Anritsu 15NN50-1.5C RF Coaxial Cable
• Aeroflex/Weinschel 1870A Power Splitter
• Anritsu PN 2000-1627-R Coaxial Cables (2)
• 10 MHz Reference Standard
Procedure
1. Confirm that the equipment settings are unchanged from the previous test. Refer to Figure 5-7
on page 5-32.
2. On the MG3700A, change the selected pattern to “FWD_RC3-5_9channel”.
3. Adjust the level of the MG3700A so that the power meter reads –30 dBm ± 0.2 dB. Then wait 15 seconds
to allow the MT821xE to update its measured results.
4. For an MT821xE with Option 42 (CDMA RF Measurements), subtract the displayed Channel Power
value from the power meter reading in Step 3. Then record the calculated Channel Power error in section
At 1930.05 MHz, –30 dBm Level, CDMA2000 in Table A-40, “Option 42 CDMA RF Measurements”
on page A-32.
5. For an MT821xE with Option 43 (cdmaOne and CDMA2000 1xRTT Demodulator), record the displayed
Freq Error, Rho, and Tau in section At 1930.05 MHz, –30 dBm Level, CDMA2000 in Table A-41,
“Option 43 cdmaOne and CDMA2000 1xRTT Demodulator” on page A-33.
6. Verify that the measured values in Step 4 or Step 5 (or both) are within specifications.
7. On the power meter, press the Sensor key, the Cal Factor soft key, and then the FREQ soft key. Use the
keypad to enter 870.03 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.
8. Set the MG3700A frequency to 870.03 MHz.
9. Adjust the MG3700A output so that the power meter reads –30 dBm ± 0.2 dB.
10. On the MT821xE, press the Freq main menu key and set 870.03 MHz as Center Frequency. Then wait
15 seconds to allow the MT821xE to update its measured results.
11. For an MT821xE with Option 42 (CDMA RF Measurements), subtract the displayed Channel Power
value from the power meter reading in Step 9. Then record the calculated Channel Power error in section
At 870.03 MHz, –30 dBm Level, CDMA2000 in Table A-40.
12. For an MT821xE with Option 43 (cdmaOne and CDMA2000 1xRTT Demodulator), record the displayed
Freq Error, Rho, and Tau into the test record in section At 870.03 MHz, –30 dBm Level, CDMA2000
in Table A-41.
13. Verify that the measured values in Step 11 or Step 12 (or both) are within specifications.
