Test Set Calibration Background
Proper test equipment calibration ensures that the test equipment and associated test cables do
not introduce measurement errors, and that measurements are correct.
If the test equipment set being used to interface with the base station has been
calibrated and maintained as a set, this procedure does not need to be performed.
(T est equipment set includes LMF computer , communications test set, additional test
equipment, associated test cables, and adapters.)
This procedure must be performed before beginning the optimization. V erify all test equipment
(including all associated test cables and adapters actually used to interface all test equipment
and the base station) has been calibrated and maintained as a set.
If an y piece of test equipment, test cable, or RF adapter , that mak es up the calibr ated
test equipment set, has been replaced, re -calibr ation must be performed. F ailure to
do so can introduce measurement errors, resulting in incorrect measurements and
degr adation to system performance.
Calibration of the communications test set (or equivalent test equipment) must
be performed at the site before calibrating the overall test set. Calibrate the test
equipment after it has been allowed to warm -up and stabilize for a minimum of 60
minutes .
