TX Calibration
WARNING
Before installing any test equipment directly to any BTS TX
OUT connector, first verify no CDMA channels are keyed.
Failure to do so can result in serious personal injury and/or
equipment damage.
CAUTION
Always wear an approved anti-static wrist strap while handling
any circuit card or module. If this is not done, there is a high
probability that the card or module could be damaged by ESD.
NOTE
At new site installations, to facilitate the complete test of each
SCCP shelf (if the shelf is not already fully populated with BBX
boards), move BBX boards from shelves currently not under test
and install them into the empty BBX slots of the shelf currently
being tested to insure that all BBX TX paths are tested.
- This procedure can be bypassed on operational sites that are
due for periodic optimization.
- Prior to testing, view the CDF file to verify the correct
BBX slots are equipped. Edit the file as required to include
BBX slots not currently equipped (per Systems
Engineering documentation).
All Cal/Audit Procedure
The LMF All Cal/Audit procedure performs the combination of the TX
calibration, TX audit, and BLO download functions with one command.
Prerequisites
Before running this procedure, be sure that the following have been
done:
The card in slot CSM 1, GLIs, MCCs, and BBXs have correct code
and data loads.
Primary CSM and MGLI are INS_ACT (bright green).
All BBXs are OOS_RAM (yellow).
If running calibration or audit using a test pattern other than Pilot,
MCCs are INS_ACT (bright green).
Test equipment and test cables are calibrated and connected for TX
calibration.
LMF is logged into the BTS in the GUI environment.
NOTE
Verify all BBX boards removed and repositioned have been
returned to their assigned shelves/slots. Any BBX boards moved
since they were downloaded will have to be downloaded again.
Follow the procedure in Table 3-40 to perform BLO calibration on the
TX paths, download BLO values to the BBXs, and perform TX path
audit in one operation.
