S The second view of the array is shown in Table 3-32. This view shows
the assignment of calibration entries in each branch to each BBX slot,
carrier, and sectorization. Three sectors are allowed for an SC4812T
Lite frame.

S When referring to the CAL file print–out and Table 3-32, 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 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
