S When referring to the CAL File Printout and Table 3-38, it can be seen
that there is one BBX Slot per sector with 20 “Calibration Entries” per
BBX (sector) for each branch. Two Calibration Entries define a single
“Calibration Point;” therefore there are ten Calibration Points in each
branch for each BBX.
– The first Calibration Entry for a Calibration Point (all odd entries)
identifies the CDMA Channel (frequency) where the BLO is
measured.
– The second Calibration Entry (all even entries) is the Power Set
Level (PwrLvlAdj) for that frequency. The valid range for
“PwrLvlAdj” is from 2500 to 27500 (2500 corresponds to
–125 dBm and 27500 corresponds to +125 dBm).
– The ten Calibration Points for each Slot–Branch Combination must
be stored in order of increasing frequency. If less than ten points
(frequencies) are calibrated, the BLO Data for the highest frequency
calibrated is written into the remainder of the ten points for that
Slot–Branch.
