MCC–DO Pilot Time Offset
The pilot time offset test verifies the transmitted pilot channel element
pilot time offset of a carrier keyed up at a specific frequency per the CDF
file.
The calibrated communications test set measures the pilot time offset in
microseconds, verifying that the result is within 3 microseconds (10
microseconds for JCDMA systems) of the target pilot time offset (zero
microseconds).
Pilot time is defined as the estimate of CDMA System Time derived
from observation of the pilot signal at the base station RF output port.
Pilot time alignment error is the difference between the measured pilot
time and the expected time, taking into account CDMA System Time
and pilot offset.
Follow the procedure in Table A-3 to test the MCC–DO Pilot Time
Offset.
Table A-3: Procedure to Test MCC–DO Pilot Time Offset
Step Action
1 Click the BBX(s) on DO carrier to be tested.
2 On the menu, click the EvDO Tests > TX>Start Manual Tx ATP.
3 Select the appropriate carrier from the Sector/Carrier list.
4 Click the OK button.
A status report window is displayed. Test results are displayed in the window.
5 Connect an MMI cable to the MCC–DO card.
6 Open a HyperTerminal application.
7 Open the COM to the MCC–DO MMI. Set parameters as follows:
S Bits per second: 9600
S Data bits: 8
S Parity: None
S Stop bits: 1
S Flow control: None
8 When the login prompt appears, enter login mmi.
