Equipment Warm-up
NOTE
Warm-up BTS equipment for a minimum of 60 minutes prior to
performing the BTS optimization procedure. This assures BTS
stability and contributes to optimization accuracy.
– 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 BBX under test OOS. Failure to do
so can result in serious personal injury and/or equipment
damage.
Automatic Cable Calibration Set–up
Figure 3-11 and Figure 3-12 show the cable calibration setup for the test
sets supported by the LMF. The left side of the diagram depicts the
location of the input and output connectors of each test equipment item,
and the right side details the connections for each test. Table 3-26
provides a procedure for performing automatic cable calibration.
Manual Cable Calibration
If manual cable calibration is required, refer to the procedures in
Appendix F.
