Required Test Equipment and Software
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
tool 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. Test equipment can, of
course, be substituted with other test equipment models if the equipment
meets the same technical specifications.
NOTE
During manual testing, you can, of course, substitute test
equipment 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. Before beginning optimization or
troubleshooting, make sure that the test equipment needed is on–hand
and operating properly.
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
tests.
Another method to account for cable 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 losses entered into the LMF before field optimization.
