Idle Slot Channel Power, Frequency Error, Rho, And Tau Tests - Anritsu Spectrum Master MS2722C Maintenance Manual

Chapter 3 — Options Verification

Idle Slot Channel Power, Frequency Error, Rho, and Tau Tests

Test Procedure
1. Ensure that the equipment settings are unchanged from the previous test. The power sensor Cal Factor
frequency should still be at 1930 MHz, and the MG3700A frequency and MS272xC Center Frequency
should still be at 1930.05 MHz.
2. On the MG3700A, change the selected pattern to FWD_IDLE.
3. Adjust the MG3700A output so that the power meter reads –50 dBm ± 0.2 dB, and record the actual
value as shown on the power meter into
Slot" on page A-47
4. Then wait 15 seconds to allow the MS272xC to update its measured results.
5. Record the "MS272xC Reading", the displayed Channel Power value, into
6. For MS272xC with Option 62 (EVDO RF Measurements), subtract the "MS272xC Reading" of displayed
Channel Power value from the "Power Meter Reading" in
Power Error" into
7. For MS272xC with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot and Tau
into Table A-112, "Option 63, At 1930.05 MHz, –50 dBm Level, Idle Slot" on page A-49.
8. Verify that the measured values in
9. On the power meter, press the Sensor key, the Cal Factor submenu key, and then the Freq submenu 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.
10. Set the MG3700A Frequency to 870.03 MHz.
11. Adjust the MG3700A output so that the power meter reads –10 dBm ± 0.2 dB, and record the actual value
as shown on the power meter into
on page A-48.
12. On the MS272xC, press the Freq main menu key, and enter 870.03 MHz as Center Freq. Then wait
15 seconds to allow the MS272xC to update its measured results.
13. Record the MS272xC displayed Channel Power value into

15. For MS272xC with Option 63 (EVDO Demodulator), record the displayed Freq Error, Rho Pilot and Tau
into Table A-113, "Option 63, At 870.03 MHz, –10 dBm Level, Idle Slot" on page A-49.
