Calibration Audit Introduction
The BLO calibration audit procedure confirms the successful generation
and storage of the BLO calibrations. The calibration audit procedure
measures the path gain or loss of every BBX transmit path at the site. In
this test, actual system tolerances are used to determine the success or
failure of a test. The same external test equipment set up is used.
NOTE
RF path verification, BLO calibration, and BLO data download
to BBXs must have been successfully completed prior to
performing the calibration audit.
Transmit (TX) Path Audit
Perform the calibration audit of the TX paths of all equipped BBX slots,
per the steps in Table 3-43.
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.
NOTE
If a successful All Cal/Audit was completed, this procedure
does not need to be performed, as BLO is downloaded as part of
the All Cal/Audit.
TX Audit Test
The Tests menu item, TX Audit, performs the TX BLO Audit test for a
BBX(s). All measurements are made through the appropriate TX output
connector using the calibrated TX cable setup.
Prerequisites
Before running this test, the following should be done:
 CSM-1,GLI3s, BBXs have correct code load.
 Primary CSM and MGLI3 are INS.
 All BBXs are OOS_RAM.
