Optimization Manual: Scope and Layout 1 Scope of This Document This document provides information pertaining to the optimization and audit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS) equipment frames equipped with trunked high–power Linear Power Amplifiers (LPAs) and their associated internal and external interfaces.
1 Optimization Manual: Scope and Layout – continued Document Composition This document covers the following major areas. Introduction, consisting of preliminary background information (such as component and subassembly locations and frame layouts) to be considered by the Cellular Field Engineer (CFE) before optimization or tests are performed.
Purpose of the Optimization 1 Why Optimize? Proper optimization and calibration assures: Accurate downlink RF power levels are transmitted from the site. Accurate uplink signal strength determinations are made by the site. What Is Optimization? Optimization compensates for the site-specific cabling and normal equipment variations. Cables that interconnect the BTS and Duplexer assemblies (if used), for example, are cut and installed at the time of the BTS frame installation at the site.
1 Purpose of the Optimization – continued 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 BBX2 board is optimized to a specific RX and TX antenna port. (One BBX2 board acts in a redundant capacity for BBX2’s 1–12, and is optimized to all antenna ports.
Required Test Equipment 1 Policy The LMF is used in conjunction with Motorola recommended test equipment and is 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. NOTE During manual testing, you can, of course, substitute test equipment with other test equipment models not supported by the LMF, but those models must meet the same technical specifications.

Test Set Calibration Test Set Calibration Background Proper test equipment calibration ensures that the test equipment and associated test cables do not introduce measurement errors, and that measurements are correct. NOTE If the test set being used to interface with the BTS has been calibrated and maintained as a set, this procedure does not need to be performed. (Test Set includes LMF terminal, communications test set, additional test equipment, associated test cables, and adapters.
Test Set Calibration – continued Selecting Test Equipment Use LMF Options from the Options menu list to select test equipment automatically (using the autodetect feature) or manually. A Serial Connection and a Network Connection tab are provided for test equipment selection. The Serial Connection tab is used when the test equipment items are connected directly to the LMF computer via a GPIB box (normal setup).
Test Set Calibration – continued Automatically Selecting Test Equipment in a Serial Connection Tab When using the auto-detection feature to select test equipment, the LMF examines which test equipment items are actually communicating with the LMF. Follow the procedure in Table 3-23 to use the auto-detect feature. Table 3-23: Selecting Test Equipment Using Auto-Detect Step 3 Action 1 From the Options menu, select LMF Options. The LMF Options window appears.
Test Set Calibration – continued Calibrating Test Equipment The calibrate test equipment function zeros the power measurement level of the test equipment item that is to be used for TX calibration and audit. If both a power meter and an analyzer are connected, only the power meter is zeroed. Use the Calibrate Test Equipment menu item from the Util menu to calibrate test equipment. The test equipment must be selected before calibration can begin.
Test Set Calibration – continued The short cable plus the TX cable configuration loss is measured – The TX cable configuration normally consists of two coax cables with type-N connectors and a directional coupler, a load, and an additional attenuator (if required by the specified BTS). The total loss of the path loss of the TX cable configuration must be as required for the BTS (normally 30 or 50 dB).
Test Set Calibration – continued Calibrating TX Cables Using a Signal Generator and Spectrum Analyzer Follow the procedure in Table 3-26 to calibrate the TX cables using a signal generator and spectrum analyzer.

Bay Level Offset Calibration Introduction to Bay Level Offset Calibration Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy. RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX2 slot) at the BTS site and stores that value in a BLO database calibration table in the LMF. The BLOs are subsequently downloaded to each BBX2.
Bay Level Offset Calibration – continued – LPA – TX filter / TX filter combiner – TX thru-port cable to the top of frame TX Path Calibration The TX Path Calibration assures correct site installation, cabling, and the first order functionality of all installed equipment. The proper function of each RF path is verified during calibration. The external test equipment is used to validate/calibrate the TX paths of the BTS.
Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a bts–n.cal calibration (BLO) offset data file in the bts–n folder. After calibration has been completed, this offset data must be downloaded to the BBX2s using the Download BLO function. An explanation of the file is shown below. NOTE Due to the size of the file, Motorola recommends that you print out a hard copy of a bts.cal file and refer to it for the following descriptions.
Bay Level Offset Calibration – continued – The second breakdown of the array is per sector. Configurations supported are Omni, 3–sector or 6–sector. Table 3-31: BTS.
Bay Level Offset Calibration – continued The 20 calibration entries for each sector/branch combination must be stored in order of increasing frequency. If less than 10 points (frequencies) are calibrated, the largest frequency that is calibrated is repeated to fill out the 10 points. Example: C[1]=384, odd cal entry = 1 ‘‘calibration point” C[2]=19102, even cal entry C[3]=777, C[4]=19086, . .
Bay Level Offset Calibration – continued TX Path Calibration The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration are derived from the site CDF files. For each BBX2, the channel frequency is specified in the ChannelList CDF file parameter and the power is specified in the SIFPilotPwr CDF file parameter for the sector associated with the BBX2 (located under the ParentSECTOR field of the ParentCARRIER CDF file parameter). 3 NOTE If both the BTS–x.

C–CCP Backplane Troubleshooting Introduction The C–CCP backplane is a multi–layer board that interconnects all the C–CCP modules. The complexity of this board lends itself to possible improper diagnoses when problems occur. Connector Functionality The following connector overview describes the major types of backplane connectors along with the functionality of each. This will allow the CFE to: Determine which connector(s) is associated with a specific problem type.
C–CCP Backplane Troubleshooting – continued Power Supply Module Interface Each power supply module has a series of three different connectors to provide the needed inputs/outputs to the C–CCP backplane. These include a VCC/Ground input connector, a Harting style multiple pin interface, and a +15 V/Analog Ground output connector. The C–CCP Power Modules convert +27 or –48 Volts to a regulated +15, +6.5, and +5.0 Volts to be used by the C–CCP shelf cards.
