All Cal/Audit Test

The Tests menu item, All Cal/Audit, performs the TX BLO Calibration

and Audit test for a XCVR(s). All measurements are made through the

appropriate TX output connector using the calibrated TX cable setup.

NOTE

If the TX calibration portion of the test passes, the BLO data is

automatically downloaded to the BBX(s) before the audit portion

of the test is run.

Prerequisites

Before running this test, ensure that the following have been done:

S CSM–1, GLIs, BBXs have correct code and data loads.

S Primary CSM and MGLI are INS.

S All BBXs are OOS_RAM.

S Test equipment and test cables are calibrated and connected for TX

BLO calibration.

S LMF is logged into the BTS.

Follow the procedure in Table 3-40 to perform the All Cal/Audit test.

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.
