TX Calibration Procedure

The LMF TX calibration procedure performs only the BLO calibration

on the TX paths. The BLO download and TX audit functions must be

performed separately when this method is chosen to perform calibration.

Prerequisites

Before running this test, 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 3-41 to perform BLO calibration on the

TX paths.

Table 3-41: 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 3-38.

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 Click Tests in the BTS menu bar, and select TX > TX Calibration... from the pull-down menus.

- A CDMA Test Parameters window will appear.

Select the appropriate carrier(s) and sector(s) (carrier-bts#-sector#-carrier#) from those displayed in the

Channels/Carrier pick list (press and hold the Shift or Ctrl keyboard key to select multiple items).

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).

Verify that the correct channel number for the selected carrier is shown in the Carrier # Channels

box.

- If it is not, obtain the latest bts-#.cdf and cbsc-#.cdf files from the CBSC.

NOTE

If necessary, the correct channel number may be manually entered into the Carrier # Channels box.
