Table 3-41: BTS TX Path Calibration
ActionStep
NOTE
Selecting PILOT (default) performs tests using a pilot signal only.
Selecting STANDARD performs tests using pilot, synch, paging and six traffic channels. This
requires an MCC to be selected.
Selecting CDFPilot performs tests using the CDF value for pilot gain and IS-97 gain values for
all the other channels included in the Standard pattern setting (paging, synch, and six traffic).
Using this pattern setting requires the selection of both a BBX and at least one MCC.
Selecting CDF performs tests using pilot, synch, paging and six traffic channels, however, the
gain for the channel elements is specified in the CDF file.
7 Click on OK.
8 Follow the cable connection directions as they are displayed.
A status report window displays the test results.
9 Click on Save Results or Dismiss to close the status report window.
Exception Handling
In the event of a failure, the calibration procedure displays a FAIL
message in the status report window and provides information in the
Description field.
Recheck the test setup and connection and re-run the test. If the tests fail
again, note specifics about the failure, and refer to Chapter 6,
Troubleshooting.
Download BLO Procedure
After a successful TX path calibration, download the BLO calibration
file data to the BBXs. BLO data is extracted from the CAL file for the
BTS and downloaded to the selected BBX devices.
NOTE
If a successful All Cal/Audit was completed, this procedure
does not need to be performed, as BLO is downloaded as part of
the All Cal/Audit.
Prerequisites
Ensure the following prerequisites have been met before proceeding.
BBXs being downloaded are OOS-RAM (yellow).
TX calibration is successfully completed.
Follow the steps in Table 3-42 to download the BLO data to the BBXs.
