This document provides information pertaining to the optimization and
audit tests of the Motorola SC4812ET Lite RF Base Transceiver Station
(BTS) equipment frame and its associated internal and external
interfaces. The following subjects are addressed: preliminary background
information; optimization, and alarm/redundancy tests; Acceptance Test
Procedures (ATP) to verify site operation and regulation compliance; site
turnover; troubleshooting.
Most applications use the same test procedure for all equipment
variations. However, decision break points are provided throughout the
procedure when equipment–specific tests are required. For example,
when tests using external test equipment are performed instead of those
using the RFDS, additional test procedures and illustrations are provided
to cover both applications.
This optimization procedure consists of a group of task-oriented tests.
Each major test category (Audit, Initial power–up, Calibration tests, etc.)
is described in chapters which are broken down into multi-page “maps.”

Assumptions and Prerequisites
Each “map” typically consists of pages containing all the information
necessary to perform the test (including all required input levels, output
levels, CDMA Local Maintenance Facility (CDMA LMF) commands,
and test points required). Also described are some of the main concepts
you must understand in the test process. Whenever possible, graphics,
flowcharts, or other examples complement the information/steps.

Purpose of the Optimization
Why Optimize?
What Is Optimization?
What Happens During
Optimization
1
Proper optimization and calibration ensures that:
S Accurate downlink RF power levels are transmitted from the site.
S Accurate uplink signal strength determinations are made by the site.
Optimization compensates for the site-specific cabling and normal
equipment variations. Site optimization guarantees that the combined
losses of the new cables and the gain/loss characteristics and built-in
tolerances of each BTS frame do not accumulate and cause improper site
operation.
Optimization identifies the accumulated loss (or gain) for each receive
and transmit path at the BTS site, and stores these values in a database.
S A receive path (RX) starts at the ancillary equipment frame RFDS RX
directional coupler antenna feedline port and travels through the RX
input port on the top of the frame, through the bandpass filter, MPC
and additional splitter circuitry, ending at a Broad Band Transceiver
(BBX) backplane slot in the CDMA Channel Processor (CCP) shelf.
S A transmit path (TX) starts at the BBX backplane slot, is routed
through the BBX I/O to the TX Combiner, travels through the ELPA,
and ends either at an antenna port on top of the frame or RFDS TX
directional coupler antenna feedline port.
Six of the seven BBX2 boards in each S–CCP shelf are optimized to
specific RX and TX antenna ports. The seventh BBX2 board acts in a
redundant capacity for BBX2 boards 1 through 6, and is optimized to all
antenna ports. A single value is generated for each complete path,
thereby eliminating the accumulation of error that would occur from
individually measuring and summing the gain and loss of each element
in the path.
BTS equipment factors in these values internally, leaving only
site–specific antenna feed line loss and antenna gain characteristics to be
factored in by the CFE when determining site ERP output power
requirements.

When to Optimize
New Installations
After the initial site installation, the BTS must be prepared for operation.
This preparation includes verifying hardware installation, initial
power–up, downloading of operating code, verifying GPS operation and
verifying transmit and receive paths.
Next, the optimization is performed. Optimization includes performance
verification and calibration of all transmit and receive RF paths, and
download of accumulated calibration data.
A calibration audit of all RF transmit paths may be performed any time
after optimization to verify BTS calibration.
After optimization, a series of manual pre–Acceptance Test Procedure
(ATP) verification tests are performed to verify alarm/redundancy
performance.
After manual pre–ATP verification tests, a series of ATPs are performed
to verify BTS performance. An ATP is also required before the site can
be placed in service.
Site Expansion
Periodic Optimization
Repaired Sites
Optimization is also required after expansion of a site.
Periodic optimization of a site may also be required, depending on the
requirements of the overall system.
IMPORTANT

Refer to Appendix B for a detailed FRU Optimization/ATP
Test Matrix outlining the minimum tests that must be
performed any time a BTS subassembly or RF cable
associated with it is replaced.

Required Test Equipment and Software
Policy
To ensure consistent, reliable, and repeatable optimization test results,
test equipment and software meeting the following technical criteria
should be used to optimize the BTS equipment. Test equipment can, of
course, be substituted with other test equipment models if the equipment
meets the same technical specifications.
It is the responsibility of the customer to account for any measurement
variances and/or additional losses/inaccuracies that can be introduced
as a result of these substitutions. Before beginning optimization or
troubleshooting, make sure that the test equipment needed is on hand
and operating properly.
T est Equipment Calibration
Optimum system performance and capacity depend on regular equipment
service, calibration, and characterization prior to BTS optimization.
Follow the original equipment manufacture (OEM) recommended
maintenance and calibration schedules closely.
1
T est Cable Calibration
Equipment Warm–up
Equipment test cables are very important in optimization. It is
recommended that the cable calibration be run at every BTS with the test
cables attached. This method compensates for test cable insertion loss
within the test equipment itself. No other allowance for test cable
insertion loss needs to be made during the performance of tests.
Another method is to account for the loss by entering it into the CDMA
LMF during the optimization procedure. This method requires accurate
test cable characterization in a shop. The cable should be tagged with the
characterization information prior to field optimization.
After arriving at the a site, the test equipment should be plugged in and
turned on to allow warm up and stabilization to occur for as long as
possible. The following pieces of test equipment must be warmed up for
a minimum of 60 minutes prior to using for BTS optimization or RFDS
calibration procedures:
S Communications test set.
S Rubidium time base.
S Power meter.
