Introduction 1 68P09255A57-2 Introduction Scope of This Document This document provides information pertaining to the optimization and audit tests of Motorola SC 4812ET Base Transceiver Subsystem (BTS) equipment frames equipped with trunked high-power Linear Power Amplifiers (LPAs) and their associated internal and external interfaces. Also covered is software release 2.16.1.

Introduction 1 68P09255A57-2 on the rear of the frame, through the DDRCs, Multicoupler Preselector Card (MPC), and additional splitter circuitry, ending at a CDMA Channel Processor (C-CCP) backplane Broad Band Transceiver (BBX) slot in the C-CCP shelf. A transmit path starts at the BBX, through the C-CCP backplane slot, travels through the LPA/Combiner TX Filter and ends at the rear of the input/output (I/O) Panel.

Introduction 68P09255A57-2 These values are factored in by the BTS equipment internally, leaving only site specific antenna feed line loss and antenna gain characteristics to be factored in by the CFE when determining site Effective Radiated Power (ERP) output power requirements. Each C-CCP shelf BBX board is optimized to a specific RX and TX antenna port. (One BBX board acts in a redundant capacity for BBXs 1-12, and is optimized to all antenna ports).

Test Equipment 68P09255A57-2 1 Test Equipment Overview The LMF is used in conjunction with Motorola recommended test equipment, and it is a part of a “calibrated test set.” To ensure consistent, reliable, and repeatable optimization test results, only recommended test equipment supported by the LMF must be used to optimize the BTS equipment. Table 1-1 outlines the supported test equipment that meets the technical criteria required for BTS optimization.

Test Equipment 1 68P09255A57-2 LMF Hardware Requirements An LMF computer platform that meets the following requirements (or better) is recommended: Notebook computer 266 MHz (32-bit CPU) Pentium processor 4 GB internal hard disk drive Color display with 1024 x 768 pixel resolution and capability to display more than 256 colors Memory requirements: - Minimum required RAM: 96 MB - Recommended RAM: - 128 MB for Windows 98 SE - 256 MB for Windows 2000 CD ROM drive and 3 1/2 inch flopp
PAGE 35
Test Equipment 68P09255A57-2 1 Test Cable Calibration Equipment test cables are very important in optimization. Motorola recommends 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 LMF during the optimization procedure.
PAGE 36
Test Equipment 68P09255A57-2 1 - This solution passes only the three minimum electrical connections between the LMF and the GPIB interface. The control signals are jumpered as enabled on both ends of the RS-232 cable (9-pin D). TX and RX signals are crossed as null modem effect. Pin 5 is the ground reference. - Short pins 7 and 8 together, and short pins 1, 4, and 6 together on each connector.
