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 3-35).
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.
Follow the procedure in Table 3-35 to perform BLO calibration on the
TX paths, download BLO values to the BBXs, and perform TX path
audit in one operation.
Table 3-35: All Cal/Audit and TX Calibration Procedure
Step Action
1 If it has not already been done, configure test equipment for TX calibration by following the
procedure in Table 3-33.
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 “Test
Pattern Drop–down Pick List” under “TX Calibration and the LMF” in this section).
4 For All Cal Audit...
– Click Tests in the BTS menu bar, and select TX > All Cal/Audit... from the pull–down menus.
A CDMA Test Parameters window will appear.
For TX Calibration
– Click Tests in the BTS menu bar, and select TX > TX Calibration from the pull–down menus.
A CDMA Test Parameters window will appear.
5
Select the appropriate carrier(s) and sector(s) (carrier-bts#-sector#-carrier#) from those displayed in the
Channels/Carrier pick list.
NOTE
To select multiple items, hold down the Shift or Ctrl key while clicking on pick list items to select
multiple carrier(s)–sector(s).
