TX Path Calibration
The TX Path Calibration assures correct site installation, cabling, and the
first order functionality of all installed equipment. The proper function
of each RF path is verified during calibration. The external test
equipment is used to validate/calibrate the TX paths of the BTS.
WARNING
Before installing any test equipment directly to any TX OUT
connector you must first verify that there are no CDMA
channels keyed. Have the OMC-R place the sector assigned to
the LPA under test OOS. Failure to do so can result in serious
personal injury and/or equipment damage.
CAUTION
Always wear a conductive, high impedance wrist strap while
handling any circuit card/module. If this is not done, there is a
high probability that the card/module could be damaged by ESD.
NOTE
At new site installations, to facilitate the complete test of each
CCP shelf (if the shelf is not already fully populated with BBX
boards), move BBX boards from shelves currently not under test
and install them into the empty BBX slots of the shelf currently
being tested to insure that all BBX TX paths are tested.
- This procedure can be bypassed on operational sites that are
due for periodic optimization.
- Prior to testing, view the CDF file to verify the correct
BBX slots are equipped. Edit the file as required to include
BBX slots not currently equipped (per Systems
Engineering documentation).
BLO Calibration Data File
During the calibration process, the LMF creates a bts-n.cal calibration
(BLO) offset data file in the bts-n folder. After calibration has been
completed, this offset data must be downloaded to the BBXs using the
Download BLO function. An explanation of the file is shown below.
NOTE
Due to the size of the file, Motorola recommends that you print
out a hard copy of a bts.cal file and refer to it for the following
descriptions.
The CAL file is subdivided into sections organized on a per slot basis (a
slot Block).
Slot 1 contains the calibration data for the 12 BBX slots. Slot 20
contains the calibration data for the redundant BBX. Each BBX slot
header block contains:
A creation Date and Time - broken down into separate parameters of
createMonth, createDay, createYear, createHour, and createMin.
The number of calibration entries - fixed at 720 entries corresponding
to 360 calibration points of the CAL file including the slot header and
actual calibration data.
