TX Calibration
WARNING
Before installing any test equipment directly to any TX OUT
connector, first verify there are no CDMA BBX channels
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.
All Cal/Audit and TX Calibration Procedure
The LMF All Cal/Audit and TX calibration procedures are essentially
identical, except for the step that selects the type of procedure desired
(Refer to Step 4 in Table 3-37).
Prerequisites
Before running this procedure, be sure that the following have been
done:
S The card in slot CSM 1, GLIs, MCCs, and BBXs have correct code
and data loads.
S Primary CSM and MGLI are INS_ACT (bright green).
S All BBXs are OOS_RAM (yellow).
S If running calibration or audit using a test pattern other than Pilot,
MCCs are INS_ACT (bright green).
S Test equipment and test cables are calibrated and connected for TX
calibration.
S 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.
All Cal Audit/TX Path Calibration procedure
Follow the procedure in Table 3-37 to perform the All Cal/Audit and TX
path calibration test.
Table 3-37: All Cal/Audit and TX Calibration Procedure
n Step Action

procedure in Table 3-35.
2 Click on the BBX(s) to be calibrated.
3 If the Test Pattern to be used is Standard, CDFPilot, or CDF, select at least one MCC (refer to
