Required Test Equipment and Software
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP 1-5
PRELIMINARY
Overview
Test Equipment and Software described in this section is required for the
Optimization Procedure. Common assorted tools such as screwdrivers
and frame Keys are also needed. Read the Owner’s Manual for all of the
Test Equipment to understand its individual operation before using the
tools in the Optimization.
Policy
To ensure consistent, reliable, and repeatable Optimization Test Results,
Test Equipment and Software meeting the following technical criteria
should be used to optimize the BTS Equipment. Before beginning
Optimization or Troubleshooting, make sure that the Test Equipment
needed is on–hand and operating properly.
Test Equipment can be substituted with other Test
Equipment Models not supported by the LMF, but those
models must meet the same technical specifications.
It is the responsibility of the customer to account for any
measurement variances and/or additional
losses/inaccuracies that can be introduced as a result of
these substitutions.
NOTE
Test Equipment Calibration
Optimum system performance and capacity depend on regular equipment
service and Calibration prior to BTS Optimization. Follow the Original
Equipment Manufacturer (OEM) recommended Maintenance and
Calibration Schedules closely.
Test Cable Calibration
Test Cables can make critical differences in Optimization accuracy. It is
recommended that Cable Calibration be run at every BTS with the
complete Test Equipment Set. This method compensates for Test Cable
Insertion Loss within the Test Equipment itself. No other allowance for
Test Cable Insertion Loss needs to be made during the performance of
the tests.
Another method to account for Test Cable Insertion Loss is by entering it
into the LMF during the Optimization Procedure. This method requires
accurate Test Cable Characterization using Shop Test Equipment.
Characterized Cables should be tagged with the Characterization
Information, and the measured Signal Losses entered into the LMF
before Field Optimization.
