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

Before installing any test equipment directly to any BTS

TX OUT connector, verify there are NO CDMA BBX

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.

WARNING

Cable Calibration Setup

Figure 3-8 shows the cable calibration setup for various supported test

sets. The left side of the diagram depicts the location of the input and

output ports of each test set, and the right side details the set up for each

test. Table 3-25 provides a procedure for calibrating cables.
