If 800 x 600 pixel resolution is used, the LMF window
must be maximized after it is displayed.
NOTE
Required Test Equipment
To ensure consistent, reliable, and repeatable optimization test results,
test equipment meeting the following technical criteria should be used to
optimize the BTS equipment. You can, of course, substitute test
equipment with other test equipment models supported by the LMF
meeting the same technical specifications.
During manual testing, you can substitute test equipment
with other test equipment models not supported by the
LMF, but those models must meet the same technical
specifications.
NOTE
The customer has the responsibility of accounting 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, calibration, and characterization prior to BTS optimization.
Follow the original equipment manufacturer (OEM) recommended
maintenance and calibration schedules closely.
Test Cable Calibration
Equipment test cables are very important in optimization. Motorola
recommends that the cable calibration be run at every BTS with the test
cables attached. 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 is to account for the loss by entering it into the LMF
during the optimization procedure. This method requires accurate test
cable characterization in a shop. The cable should be tagged with the
characterization information prior to field optimization.
