Equipment Warm-up
NOTE
To assure BTS stability and contribute to optimization accuracy
of the BTS, warm-up the BTS test equipment prior to
performing the BTS optimization procedure as follows:
– Agilent E7495A for a minimum of 30 minutes
– All other test sets for a minimum of 60 minutes
Time spent running initial or normal power-up, hardware/
firmware audit, and BTS download counts as warm-up time.
WARNING
Before installing any test equipment directly to any BTS TX
OUT connector, verify there are no CDMA channels keyed.
– At active sites, have the OMC-R/CBSC place the antenna
(sector) assigned to the LPA under test OOS. Failure to do
so can result in serious personal injury and/or equipment
damage.
