The followinglist outlines the folder structure for LMF. Except for the bts-nnn folders,these folders are created as part of the LMF installation. Refer to theCDMA LMF Operator’s Guide for a complete description of the folderstructure.Figure 3-1: LMF Folder Structureversion folder (A separate folder isrequired for each different version; forexample, a folder name 2.8.1.1.1.5.)loads folder(C:)x:\<lmf home directory> foldercdma foldercode folderdata folderBTS-nnn folders (A separate folder isrequired for each BTS where bts-nnn is theunique BTS number; for example, bts-163.)NOTE The “loads” folder and all the folders below it are not availablefrom the LMF for Software Release 2.16.1.x. These folders maybe present as as a legacy from previous software versions ordownloaded from the CBSC/OMC-R.3

DO NOT remove the span linecable connectors until the OMC-R/CBSC has disabled the BTS.Each frame is equipped with one 50-pair punchblock for spans,customer alarms, remote GPS, and BTS frame alarms. See Figure 3-4and refer to Table 3-6 for the physical location and punchdown locationinformation.Before connecting the LMF computer to the frame LAN, theOMC-R/CBSC must disable the BTS and place it OOS. This will allowthe LMF to control the BTS, and prevent the CBSC from inadvertentlysending control information to the BTS during LMF-based tests.Isolate BTS from T1/E1 SpansOnce the OMC-R/CBSC has disabled the BTS, the spans must bedisabled to ensure the LMF will maintain control of the BTS. To disablethe spans, disconnect the BTS-to-CBSC Transcoder span cableconnectors from the Span I/O cards (Figure 3-2).Figure 3-2: Disconnecting Span LinesSpan Line CableConnectors4812ETL0020-13

The M-PATH 437 Channel Service Unit (CSU) module providesin-band SNMP-managed digital service access to E1 and fractional E1lines. CSU modules plug into the CSU shelf (see Figure 3-3).The CSU shelf can support two M-PATH 537 or two M-PATH 437 CSUmodules. A 537 CSU module supports a single T1 span connection. A437 CSU module supports a single E1 span connection.Remote M-PATH management is available through SNMP over anin-band data link on the span line (using a facility data link or8-64 Kbps of a DS0 channel). The unit at the near end of themanagement path can be an SNMP manager or another M-PATH CSU.Programming of the M-PATH is accomplished through the DCE 9-pinconnector on the front panel of the CSU shelf. Manuals and an MSWindows programming disk are supplied with each unit.For more information refer to M-PATH T1 Channel Service Unit User’sGuide, Kentrox part number 65-77538101 or the ADC M-PATH E1Channel Service Unit User’s Guide, Kentrox part number 1174139.Setting the Control PortWhichever control port is chosen, it must first be configured so thecontrol port switch settings match the communication parameters beingused by the control device. If using the rear-panel DTE control port, setthe SHELF ADDRESS switch SA5 to “up.” If using the rear-panel DCEcontrol port, position the SHELF ADDRESS switch down.For more information, refer to the 2-Slot Universal Shelf InstallationGuide, Kentrox part number 65-78070001, the M-PATH T1 ChannelService Unit Installation Guide, Kentrox part number 65-77538001, orthe M-PATH E1 Channel Service Unit Installation Guide, Kentrox partnumber 1174662, depending on installed equipment.Plug one of the cables listed below into the Control Port connectors:Part Number Description of Cable01-95006-022 (six feet) DB-9S to DB-9P01-95010-022 (ten feet)The control port cables can be used to connect the shelf to:3

ROM code is loaded in all devices duringmanufacture, factory repair, or, for software upgrades, from the CBSCusing the DownLoad Manager (DLM). Device application (RAM) codeand data must be downloaded to each equipped device by the user beforethe BTS can be made fully functional for the site where it is installed.ROM CodeDownloading ROM code to BTS devices from the LMF is NOT routinemaintenance or a normal part of the optimization process. It is onlydone in unusual situations where the resident ROM code release level inthe device is not compatible with the required release level of the siteoperating software and the CBSC can not communicate with the BTS toperform the download. An example would be a BTS loaded with R16.0software where a GLI which is factory-loaded with R9.2.x or earlierROM code must be installed to replace a malfunctioning GLI.Before ROM code can be downloaded from the LMF, the correct ROMcode file for each device to be loaded must exist on the LMF computer.ROM code must be manually selected for download.NOTE The ROM code file is not available for GLI3s. GLI3s are ROMcode loaded at the factory.ROM code can be downloaded to a device that is in any state. After thedownload is started, the device being downloaded will change toOOS_ROM (blue). The device will remain OOS_ROM (blue) when thedownload is completed. A compatible revision-level RAM code mustthen be downloaded to the device. Compatible code loads for ROM andRAM must be used for the device type to ensure proper performance.The compatible device code release levels for the BSS software releasebeing used are listed in the Version Matrix section of the SCt CDMARelease Notes (supplied on the tape or CD-ROM containing the BSSsoftware).Procedures to load ROM code are located in Appendix G.RAM CodeBefore RAM code can be downloaded from the LMF, the correct RAMcode file for each device must exist on the LMF computer. RAM codecan be automatically or manually selected depending on the Devicemenu item chosen and where the RAM code file for the device is storedin the LMF file structure. The RAM code file will be selectedautomatically if the file is in the <x>:\<lmf homedirectory>\cdma\loads\n.n.n.n\code folder (where n.n.n.n is thedownload code version number that matches the “NextLoad” parameterof the CDF file). The RAM code file in the code folder must have thecorrect hardware bin number for the device to be loaded.RAM code can be downloaded to a device that is in any state. After thedownload is started, the device being loaded will change to OOS_ROM(blue). When the download is completed successfully, the device willchange to OOS_RAM (yellow).3

The CSM will change tothe Enabled state after phase lock is achieved.NOTEThe GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operatedby the United States Department of Defense (DOD). The DOD periodically alters satellite orbits;therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an ephemeris(satellite position table) that is updated periodically to take these changes into account.If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the GPSreceiver ephemeris to be updated.Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3-D position fixfor a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiverneeds to track only one satellite, depending on accuracy mode set during the data load).NOTESIf two CSMs are installed and the board in slot CSM 1 has enabled, the LMF CSM cage viewshould show slot CSM 1 as bright green (INS-ACT) and slot CSM 2 as olive green (INS-SBY)SIf more than an hour has passed without the board in slot CSM 1 enabling, refer to the CSM SystemTime - GPS & LFR/HSO Verification section of this chapter (see Table 3-23, Figure 3-9, andTable 3-24) to determine the cause.4After CSMs have been successfully enabled, be sure the PWR/ALM LEDs are steady green(alternating green/red indicates the card is in an alarm state). 3

CSM System Time - GPS & LFR/HSO Verification 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY3-38CSM System Time - GPS & LFR/HSO VerificationClock Synchronization Manager (CSM) Sub-system DescriptionOverview - Each BTS CSM sub-system features two CSM boards perRFMF. The primary function of the CSM cards is to maintain CDMAsystem time. GPS is used as the primary timing reference andsynchronizes the entire cellular system. In typical operation, the primaryCSM locks its Digital Phase Locked Loop (DPLL) circuits to GPSsignals. These signals are provided by either an on-board GPS receivermodule (RF-GPS) or a remote GPS receiver (RGPS). RGPS uses a GPSreceiver in the antenna head that has a digital output. The secondgeneration CSM card (CSM-II) is required when using the RGPS. ACSM-II card can also be equipped with a local GPS receiver daughtercard to support an RF-GPS signal.SCCP Shelf CSM Card Slot Assignments - The GPS receiver isinterfaced to the board in SCCP shelf slot CSM 1. This card is theprimary timing source, while the card in slot CSM 2 providesredundancy. The redundant card, does not have a GPS receiver.CSM-II Card Type Description - Each CSM-II card features atemperature-stabilized crystal oscillator that provides 19.6608 MHzclock, even second pulse, and 3 MHz reference signals to thesynchronization source selected from the following (refer to Table 3-24for source selection/verification procedures):SGPS: local/RF-GPS or remote/RGPSSLORAN-C Low Frequency Receiver (LFR) or High StabilityOscillator (HSO)SExternal reference oscillator sourcesCDMA Clock Distribution Card (CCD) Description - CCD cardsbuffer and distribute even-second reference and 19.6608 MHz clocksignals from the CSM cards. CCD 1 is married to the card in slot CSM1, and CCD 2 is married to the card in slot CSM 2.CSM Card Redundancy - The BTS switches between the primary andredundant units (card slots CSM 1 and CSM 2, respectively) upon failureor command. A failure in CSM 1 or CCD 1 will cause the system toswitch to the CSM 2-CCD 2 redundant card pair. GPS timingsynchronization is continually maintained between the primary andredundant CSM-CCD pairs.Secondary Timing References - The BTS may be equipped with aLORAN-C Low Frequency Receiver (LFR), a High Stability Oscillator(HSO), or external 10 MHz Rubidium source which the CSM can use asa secondary timing reference. Continuous GPS synchronization ismaintained for the LFR or HSO secondary timing references. The CSMmonitors and determines what reference to use at a given time.3

Duringnormal operation, the card in slot CSM 1 selects GPS as the primarytiming source (Table 3-24). The source selection can also be overriddenvia the LMF or by the system software.Low Frequency Receiver/High Stability OscillatorGeneralThe CSM and the LFR/HSO - The CSM performs the overallconfiguration and status monitoring functions for the LFR/HSO. In theevent of GPS failure, the LFR/HSO is capable of maintainingsynchronization initially established by the GPS reference signal.LFR - The LFR requires an active external antenna to receiveLORAN-C RF signals. Timing pulses are derived from this signal,which is synchronized to Universal Time Coordinates (UTC) and GPStime. The LFR can maintain system time indefinitely after initial GPSlock.HSO - The HSO is a high stability 10 MHz oscillator with the necessaryinterface to the CSMs. The HSO is typically installed in thosegeographical areas not covered by the LORAN-C system. Since theHSO is a free-standing oscillator, system time can only be maintainedfor 24 hours after 24 hours of GPS lockUpgrades and Expansions: LFR2/HSO2/HSOXThe LFR2 and HSO2 (second generation cards) both can export a timingsignal to other BTS frames located at a site. These secondary framesrequire an HSO-expansion (HSOX) module whether the primary framehas an LFR2 or an HSO2. The HSOX accepts input from the primaryframe and interfaces with the CSM cards in the secondary frames. LFRand LFR2 use the same source code in source selection (Table 3-24).HSO, HSO2, and HSOX use the same source code in source selection(Table 3-24).NOTE Allow the base site and test equipment to warm up for 60minutes after any interruption in oscillator power. CSM cardwarm-up allows the oscillator oven temperature and oscillatorfrequency to stabilize prior to test. Test equipment warm-upallows the Rubidium standard time base to stabilize in frequencybefore any measurements are made.3

Test Set Calibration68P09255A69-3Aug 2002 1X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY3-65Test Set CalibrationBackgroundProper test equipment calibration helps to ensure accurate BTSoptimization and acceptance testing by assuring that the test equipmentand associated cables do not introduce measurement errors.NOTE If the test equipment set (see the Terms and Abbreviationssection of Chapter 1) being used to optimize or test the BTS hasbeen calibrated and maintained as a set, this procedure does notneed to be performed.This procedure must be performed before the optimization. Verify all testequipment (including all associated cables and adapters actually used tointerconnect test equipment items and the BTS) has been calibrated andmaintained as a set.CAUTION If any piece of test equipment, test cable, or RF adapter, thatmakes up the calibrated test equipment set has been replaced, theset must be re-calibrated. Failure to do so can introducemeasurement errors, resulting in incorrect measurements anddegradation to system performance. Motorola recommendsrepeating cable calibration before testing at each BTS site.NOTE Calibration of the communications system analyzer (orequivalent test equipment) must be performed at the site beforecalibrating the overall test equipment set. Calibrate the testequipment after it has been allowed to warm-up and stabilize fora a minimum of 60 minutes.Calibration Procedures IncludedAutomaticProcedures included in this section use the LMF automated calibrationroutine to determine path losses of the supported communicationsanalyzer, power meter, associated test cables, adapters, and (if used)antenna switch that make up the overall calibrated test equipment set.After calibration, the gain/loss offset values are stored in a testmeasurement offset file on the LMF computer.ManualAgilent E4406A Transmitter Tester - The E4406A does not supportthe power level zeroing calibration performed by the LMF. If thisinstrument is to be used for Bay Level Offset calibration and calibrationis attempted with the LMF Calibrate Test Equipment function, theLMF will return a status window failure message stating that zeroingpower is not supported by the E4406A. Refer to the EquipmentCalibration section of Appendix F for instructions on using theinstrument’s self-alignment (calibration) function prior to performingBay Level Offset calibration.3

Refer to the Equipment Calibrationsection of Appendix F for E4406A calibration.PrerequisitesSLMF computer serial port and test equipment are connected to theGPIB box.STest equipment is turned on and has warmed up for at least 60minutes.STest equipment has been selected in the LMF (Table 3-28 orTable 3-29)Follow the procedure in Table 3-30 to calibrate the test equipment.Table 3-30: Test Equipment CalibrationStep Action1 Click Util in the BTS menu bar, and select Calibrate Test Equipment from the pull-down menu.-A Directions window will be displayed.2Follow the direction provided.3Click on Continue to close the Directions window and start the calibration process.-A status report window is displayed.4Click on OK to close the status report window. Calibrating Cables - OverviewThe LMF Cable Calibration function is used to measure the path loss(in dB) for the TX and RX cables, adapters, directional couplers, andattenuators that make up the cable configurations used for testing. Acommunications system analyzer is used to measure the loss of both theTX test cable and the RX test cable configurations. LMF cablecalibration consists of the following processes:1. Measure the loss of a short cable. This is done to compensate for anymeasurement error of the communications system analyzer. Theshort cable, which is used only for the calibration process, isconnected in series with both the TX and RX test cableconfigurations when they are measured. The measured loss of theshort cable is deducted from the measured loss of the TX and RXtest cable configurations to determine the actual loss of theconfigurations. This deduction is done so any error in the analyzermeasurement will be adjusted out of both the TX and RXmeasurements.3
Test Set Calibration 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY3-702. Measure the loss of the short cable plus the RX test cableconfiguration. The RX test cable configuration normally consistsonly of a coax cable with type-N connectors that is long enough toreach from the BTS RX connector to the test equipment. When theBTS antenna connectors carry duplexed TX and RX signals, adirectional coupler and, if required by BTS type, an additionalattenuator are also required for the RX test cable configuration.These additional items must be included in the path lossmeasurement.3. Measure the loss of the short cable plus the TX test cableconfiguration. The TX test cable configuration normally consists oftwo coax cables with type-N connectors, a directional coupler, atermination load with sufficient rating to dissipate the BTS outputpower, and an additional attenuator, if required by the BTS type. Thetotal path loss of the TX test configuration must be as required forthe BTS (normally 30 or 50 dB). The Motorola Cybertest analyzer isdifferent from other communications system analyzers because therequired attenuation/load is built into the test set. Because of this,the Cybertest TX test configuration consists only of the requiredlength coax cable.Calibrating Test Cable Configurations with a Communications SystemAnalyzerNOTE LMF cable calibration cannot be accomplished with anHP8921A analyzer for 1.9 MHz. A different analyzer type or thesignal generator and spectrum analyzer method (Table 3-32 andTable 3-33) must be used. Cable calibration values must bemanually entered into the LMF cable loss file if the signalgenerator and spectrum analyzer method is used. To use theHP8921A for manual test cable configuration calibration for 800MHz BTSs, refer to the Manual Cable Calibration section ofAppendix F.PrerequisitesSTest equipment is turned on and has warmed up for at least 60minutes.STest equipment has been selected in the LMF (Table 3-28 orTable 3-29).STest equipment has been calibrated and correctly connected for thetype of test cable configuration to be calibrated.Refer to Figure 3-10 or Figure 3-11 and follow the procedure inTable 3-31 to calibrate the test cable configurations.Table 3-31: Test Cable Configuration Calibration with a Communications System AnalyzerStep Action1 Click Util in the BTS menu bar, and select Cable Calibration... in the pull-down menu.-A Cable Calibration window is displayed.. . . continued on next page3

Bay Level Offset Calibration 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY3-76Bay Level Offset CalibrationPurpose of Bay Level Offset CalibrationBay Level Offset (BLO) calibration is the central activity of theoptimization process. BLO calibration compensates for normalequipment variations within the BTS RF paths and assures the correcttransmit power is available at the BTS antenna connectors to meet siteperformance requirements.What is BLO Calibration?DescriptionBLO calibration is the complete title of what is normally referred to as“calibration.” Calibration identifies the accumulated gain in everytransmit path at the BTS site. The transmit path BLO values determinedduring calibration are stored in the LMF calibration data file, and aresubsequently downloaded to each BBX. When transmit path calibrationis performed, receive path BLO values will automatically be set to thedefault value in the LMF calibration file and downloaded.BTS RF Path DescriptionsTransmit (TX) path - A TX path starts at an SCCP shelf BBXbackplane slot, travels through the CIO card, is routed to the LinearPower Amplifier (LPA) trunking module for sector phase shifting,through the LPAs, back through the LPA trunking module for sectorphase selection, through the TX bandpass filter (starter frames) or 2:1TX combiner (companion frames), through the Transmit & Receive DualDirectional Coupler (TRDC) or Duplexer Directional Coupler (DRDC),and ends at the TRDC TX or DRDC antenna connector.Receive (RX) main path - A main RX path starts at ANTENNASconnectors 1A, 2A, or 3A and travels through the associated TRDC orDRDC, the MPC in SCCP cage slot MPC-1, the CIO card, andterminates at a backplane BBX slot in the SCCP shelf.Diversity RX path - Diversity RX paths differ for SC4812ET Litestarter (stand-alone) and companion frames. The following describe eachtype of path:SStarter frame diversity RX path - A starter frame diversity RX pathis the same as a main RX path except that it starts at ANTENNASconnectors 1B, 2B, or 3B, travels through the associated TRDC orDRDC, and the MPC card in SCCP cage slot MPC-2 (refer toTable 1-5).SCompanion frame diversity RX path - The companion frame mainRX signal is used for the collocated companion frame diversity RXsignal. A companion frame’s diversity RX path starts at ANTENNASconnectors 1A, 2A, or 3A in the collocated companion frame. Ittravels through the associated TRDC or DRDC, the MPC in SCCPcage slot MPC-1, and the CIO card where it is then routed out of the3

The signal travelsthrough the inter-frame diversity RX cables, into the RX expansion inports (RX EXPANSION 1B, 2B, or 3B in Figure 1-9 or Figure 1-10)of the companion frame, through the Expansion MPC (EMPC) inSCCP cage slot MPC-2, the CIO, and terminates at a backplane BBXslot in the SCCP shelf.SRFDS sampling paths - Directional couplers for RFDS signalsampling are integral to the SC4812ET Lite transmit and receive pathsin the DRDCs and TRDCs. Cables connect from these directionalcouplers to the RFDS input connectors.Component Verification During CalibrationTX Path CalibrationTX path calibration supports verification of correct BTS installation, RFcabling installation and performance, functionality of all equipmentinstalled in the transmit RF chain, and the proper functioning of eachtransmit RF path. External test equipment is used to calibrate and auditthe TX paths of the BTS.RX Path CalibrationRX path calibration is not required or supported on CDMA BTSsystems. Default RX calibration values are written to the RX calibrationdata files during the TX calibration process. RX functionality is verifiedduring Frame Erasure Rate (FER) testing.When to CalibrateCalibration to determine BLO:1. Is required after initial BTS installation.2. Must be done once each year for an operational BTS site.3. Is recommended by Motorola for all associated RF paths afterreplacing any of the following components:- BBX card- SCCP shelf- CIO card- CIO-to-LP A trunking module RF cable- LPA trunking module-LPA- Trunking module-to-TX filter/filter combiner RF cable- TX filter or TX filter combiner- TX filter/filter combiner-to-DRDC/TRDC cable- DRDC or TRDCBLO Calibration Data FileDuring the calibration process, the LMF creates a calibration (CAL) datafile where BLO values are stored. After calibration has been completed,these offset values must be downloaded to the BBXs using the LMFBLO download function. A detailed description of the file organizationand content is provided in the following paragraphs3
Bay Level Offset Calibration 68P09255A69-3Aug 20021X SCt4812ET Lite BTS Optimization/ATP Software Release 2.16.1.xPRELIMINARY3-78NOTE Due to the size of the file, Motorola recommends printing out acopy of a bts- #.cal file and referring to it for the followingdescriptions.CAL File OrganizationThe CAL file is subdivided into three sections called “slot Blocks”.These are:1. Slot[1] Block which contains the calibration data for the six primaryBBX slots.2. Slot[20] Block which contains the calibration data for the redundantBBX (see Table 3-37).3. Slot[385] Block which contains the calibration data for the RFDS.BBX Slot Block PartsBBX slot Blocks are further subdivided into the parts described in thefollowing:Slot Block Header - Each BBX slot Block has a header section (slotheader) which contains:SA creation Date and Time - broken down into separate parameters ofcreateMonth, createDay, createYear, createHour, and createMin.SThe number of calibration entries in the file - the numBayLevelPtsparameter. The parameter is fixed at 720 entries for SC4812-seriesframes. These 720 entries are combined to define the 360 calibrationpoints of the CAL file.SThe slot Block format parameter.Slot Block Bay Level Calibration Data - Each BBX slot Block has aBay Level Calibration data section (BayLevelCal) which is organized asa large flat array. The array is organized by branch, SCCP cage BBXslot, and calibration entries. There are several ways to look at the arraycontents. Two different views are provided in the following to illustratethe significant features of BayLevelCal section content and organization:SThe first view of the array is shown in Table 3-36.

Two calibration entries define asingle “calibration point;” therefore there are ten calibration points ineach branch for each BBX.- The first entry for a calibration point (all odd entries) identifies theCDMA channel (frequency) where the BLO is measured. Thesecond calibration entry (all even entries) is the power set level(PwrLvlAdj) for that frequency. The valid range for PwrLvlAdj is3

If less than ten points(frequencies) are calibrated, the BLO data for the highest frequencycalibrated is written into the remainder of the ten points for thatslot-branch.Example:C[1]=384 (odd cal entry)C[2]=19102 (even cal entry)C[3]=777 (odd cal entry)C[4]=19086 (even cal entry)C[19]=777 (odd cal entry)C[20]=19086 (even cal entry)...= 1 “calibration point”= 1 “calibration point”= 1 “calibration point”In the example above, BLO was measured at only two frequencies(channels 384 and 777) for SCCP slot BBX-1 transmit (Table 3-37).The BLO data for the highest frequency measured (channel 777) willbe written to the remaining eight transmit calibration points (definedby entries C[5] through C[20]) for BBX-1.Slot Block Temperature Compensation - Each BBX slot Block alsohas a temperature compensation data section (TempLevelCal) wherepower level compensation factors for temperature variations are stored.CAL File and BLO Data DownloadWhen BLO data is downloaded to the BBXs after calibration, the data isdownloaded to the devices in the order it is stored in the CAL file. TXcalibration data (entries C[1] - C[60]) are sent first. Data for the tenBBX slot 1 calibration points (entries C[1] - C[20]) are sent initially,followed by data for the ten BBX slot 2 calibration points (entries C[21]- C[40]), and so on. The RX calibration data is sent next in BBX slotsequence, followed by RX Diversity calibration data.Test Equipment Setup for RF Path CalibrationFollow the steps outlined in Table 3-38 and refer as needed toFigure 3-13 or Figure 3-14 to set up test equipment.Table 3-38: Set Up Test Equipment for RF Path CalibrationStep Action1If it has not already been done, refer to the procedure in Table 3-10 to interface the LMFcomputer terminal to the frame LAN A connector.2If it has not already been done, refer to Table 3-11 to start a GUI LMF session.3If required, calibrate the test equipment per the procedure in Table 3-30.3

CAUTIONTo prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dBdirectional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in-line attenuator for 1900MHz.For TX path calibration, connect the test equipment as shown in Figure 3-13, Figure 3-14, orFigure 3-15, depending on the communications analyzer being used.Transmit (TX) Path Calibration DescriptionThe assigned channel frequency and desired power level at the frame TXports for transmit calibration are derived from the BTS CDF file. EachBBX at the site is assigned to a sector and carrier. These are specifiedrespectively in the sector and carrier fields of the ParentCARRIERparameter in each BBXs CDF file block. The channel frequency anddesired power for the assigned sector are specified respectively in theChannelList and SIFPilotPwr parameters of the CDF block for theCARRIER to which the BBX is assigned.NOTE Be sure the bts-#.cdf and cbsc-#.cdf files loaded on the LMFcomputer are current. The LMF will obtain carrier and channelinformation from these files and insert it into the appropriateCDMA Test Parameter screen. Failure to have the most currentfiles from the CBSC can result in incorrect channel informationbeing used to calibrate the BTS and unfavorable affects on BTSperformance. Carrier and channel numbers should only beentered manually for special test cases or as a last resort.The calibration process attempts to adjust the measured power to within+0.5 dB of the desired power. The calibration will pass if the error is lessthan +1.5 dB.The TX BLO for the SC4812ET Lite is approximately 42.0 dB ±5.0 dB.BLO is the gain in dB between the known power output of the BBX andthe measured power at the TX port. BLO is derived by deducting theknown BBX power output from the power measured at the TX port or(Measured Power) - (BBX TX Power Output).Example:Measured Power (at TX port) = 36.0 dBmKnown BBX TX Power Output = -6.0 dBmBLO = (36.0) - (-6.0) = 42.0 dB gain3

TheAll Cal/Audit... selection initiates a series of actions to perform TXcalibration, and if calibration is successful, download BLO and performTX audit. The TX Calibration... selection performs only TXcalibration. When TX Calibration... is used, BLO download and TXaudit must be performed as separate activities. The CDMA TestParameters window which opens when TX Calibration... or AllCal/Audit... is selected contains several user-selectable features whichare described in the following subsections.Rate Set Drop-down Pick ListThe Rate Set Drop-down Box is enabled if at least one MCC card isselected for the test. The available options for TX tests are 1 = 9600, and3 = 9600 1X. Option 3 is only available if 1X cards are selected for thetest. The available transfer rate options for RX tests are 1 = 9600 and2 = 14400. Option 2 is only available if no 1X cards are selected.Verify BLO CheckboxA Verify BLO checkbox is provided and checked by default. After theactual TX calibration is completed, the BLO derived from the calibrationis compared to a standard, acceptable BLO tolerance for the BTS. Insome installations, additional items may be installed in the transmit path.The additional change in gain from these items could cause BLOverification failure and, therefore, failure of the entire calibration. Inthese cases, either the Verify BLO checkbox should be unchecked or theadditional path losses should be added into each applicable sector usingthe Util > Edit > TX Coupler Loss... function.Single-Sided BLO CheckboxAn acceptable range of BLO values for each type of BTS is establishedto allow for tolerance variations in all the components of the RF chain.This acceptable range, 42+5 dB for example, is very wide toaccommodate the redundant BBX in the BTS. This is a much widertolerance than necessary for the primary BBXs. Primary BBXs normallywill have BLOs in the lower half of the range. Using the example range,this would be from 37 to 42 dB. Checking the Single-Sided BLOcheckbox should only be done when calibrating primary BBXs becauseit will reduce the acceptable BLO value variations to the lower half ofthe range. Because this is a much more stringent tolerance, calibrationsrun with Single-Sided BLO are more likely to fail and should only beattempted by an experienced CFE. Never select Single-Sided BLOwhen calibrating a redundant BBX.3

Calibration Audit IntroductionThe BLO calibration audit procedure confirms the successful generationand storage of the BLO calibration values. The calibration auditprocedure measures the path gain or loss of every BBX transmit path atthe site. In this test, actual system tolerances are used to determine thesuccess or failure of a test. The same external test equipment set-uprequired for TX calibration is used for TX audit.*RF path verification, BLO calibration, and BLO datadownload to BBXs must have been successfully completedprior to performing the calibration audit.IMPORTANTTX Path AuditPerform the calibration audit of the TX paths of all equipped BBX slots,per the steps in Table 3-43.Before installing any test equipment directly to any TXOUT connector, first verify there are no CDMA BBXchannels keyed. Failure to do so can result in seriouspersonal injury and/or equipment damage.WARNINGIf a successful All Cal/Audit was completed, thisprocedure does not need to be performed, as BLO isdownloaded as part of the All Cal/Audit.NOTETX Audit TestThe Tests menu item, TX Audit, performs the TX BLO Audit test forBBXs. All measurements are made through the appropriate TX outputconnector using the TX calibration setup.3

The power level is then measuredat the TX antenna directional coupler by the power measuring testequipment item being used (power meter or analyzer). The difference(offset) between the power level at the RFDS and the power level at theTX antenna directional coupler is used as the TX RFDS calibrationoffset value.RX Path Calibration - For an RX antenna path calibration the RFDS iskeyed at a pre-determined power level and the power input level ismeasured by the BTS BBX. A CDMA signal at the same power levelmeasured by the BTS BBX is then injected at the RX antenna directionalcoupler by the communications system analyzer. The difference (offset)between the RFDS-keyed power level and power level measured at theBTS BBX is the RFDS RX calibration offset value.RFDS calibration and the CAL file - The TX and RX RFDScalibration offset values are written to the CAL file in the slot[385]Block.TSIC channel frequency - For each RFDS TSIC, the channelfrequency is determined at the lower third and upper third of theappropriate band using the frequencies listed in Table 3-50.Table 3-50: RFDS TSIC Calibration Channel FrequenciesSystem Channel Calibration Points800 MHz (A and B) 341 and 6821.9 GHz 408 and 791Before installing any test equipment directly to any TXOUT connector, verify that there are no CDMA channelskeyed.
