Ten calibration points per sector are supported for each branch. Two
entries are required for each calibration point.
The first value (all odd entries) refer to the CDMA channel
(frequency) where the BLO is measured. The second value (all even
entries) is the power set level. The valid range for PwrLvlAdj is from
2500 to 27500 (2500 corresponds to -125 dBm and 27500
corresponds to +125 dBm).
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, the largest frequency that is calibrated is
repeated to fill out 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 cal points were calibrated this
would be repeated for the next 8 points)
When the BBX is loaded with image = 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
points (C[21] - C[40]), etc. The RxCal data is sent next (C[241] -
C[480]), followed by the RxDCal data (C[481] - C[720]).
Temperature compensation data is also stored in the cal file for each
set.
