S Ten calibration points per sector are supported for each branch. Two
entries are required for each calibration point:
1. The first value (all odd entries) identifies the CDMA channel
(frequency) where the BLO is measured.
2. The second value (all even entries) is the power set level
(PwrLvlAdj). The valid range for PwrLvlAdj is from 2500 to
27500 (2500 corresponds to –125 dBm and 27500 corresponds
to +125 dBm).
S The 20 calibration entries for each sector/branch combination must be
stored in order of increasing frequency. If less than 10 points
(frequencies) are calibrated, data for the highest frequency calibrated
is repeated to fill out the remainder of the 10 points.
Example:
C[1]=384, odd cal entry
= 1 ‘‘calibration point”
C[2]=19102, even cal entry
C[3]=777,
C[4]=19086,
.
.
C[19]=777,
C[20]=19086, (Since only two frequencies were calibrated, data for
this one, the highest, is repeated for the last eight
calibration points of the sector/branch)
S When the BBX is loaded with data, the CAL file data for the BBX is
downloaded to the device in the order it is stored in the CAL file.
TxCal data is sent first, C[1] – C[240]. Sector 1’s ten calibration
points are sent (C[1] – C[20]) followed by sector 2’s ten calibration
