SC 4812T CDMA BTS Optimization/ATP
Purpose
This section covers other test equipment and peripherals not covered in
Chapter 3. Procedures for the manual testing are covered here, along
with procedures to calibrate the TX and RX cables using the signal
generator and spectrum analyzer.
Equipment Warm up
Warm-up BTS equipment for a minimum of 60 minutes
prior to performing the BTS optimization procedure. This
assures BTS site stability and contributes to optimization
accuracy. (Time spent running initial power-up, hardware/
firmware audit, and BTS download counts as warm-up
time.)
IMPORTANT
*
If any piece of test equipment (i.e., test cable, RF adapter)
has been replaced, re-calibration must be performed.
Failure to do so could introduce measurement errors,
resulting in incorrect measurements and degradation to
system performance.
CAUTION
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.
