Download the BTS08/01/2001 3-311X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYOverviewBefore a BTS can operate, each equipped device must contain deviceinitialization (ROM) code. ROM code is loaded in all devices duringmanufacture or factory repair. Device application (RAM) code and datamust be downloaded to each equipped device by the user before the BTScan be made fully functional for the site where it is installed.ROM CodeDownloading ROM code to BTS devices from the CDMA LMF is NOTroutine maintenance or a normal part of the optimization process. It isonly done in unusual situations where the resident ROM code in thedevice does not match the release level of the site operating softwareAND the CBSC can not communicate with the BTS to perform thedownload. An example would be a BTS loaded with Release 9.2software where a GLI loaded with Release 2.8.1 ROM code must beinstalled to replace a malfunctioning MGLI.Before ROM code can be downloaded from the CDMA LMF, the correctROM code file for each device to be loaded must exist on the LMFcomputer. ROM code must be manually selected for download.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. The same Revision–level RAM code must thenbe downloaded to the device. For example, if Release 2.9.2.1.1 ROMcode is downloaded, Release 2.9.2.1.1 RAM code must be downloaded.Procedures to load ROM code are located in Appendix G.RAM CodeBefore RAM code can be downloaded from the CDMA LMF, the correctRAM code file for each device must exist on the LMF computer. RAMcode can be automatically or manually selected depending on the Devicemenu item chosen and where the RAM code file for the device is storedin the CDMA LMF file structure. The RAM code file will be selectedautomatically if the file is in the \lmf\cdma\loads\n.n.n.n\code folder(where n.n.n.n is the version number of the download code that matchesthe “NextLoad” parameter of the CDF file). The RAM code file in thecode folder must have the correct hardware bin number.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). When code is downloaded to an MGLIor GLI, the CDMA LMF automatically also downloads data and thenenables the MGLI. When enabled, the MGLI will change to INS (green).For non–GLI devices, data must be downloaded after RAM code isdownloaded. To download data, the device state must be OOS–RAM(yellow).3

A status report window is displayed showing the results of the selectionaction.7Click on the OK button to close the status report window. Enable CSMsEach BTS CSM system features two CSM boards per site. In a typicaloperation, the primary CSM locks its Digital Phase Locked Loop(DPLL) circuits to GPS signals. These signals are generated by either anon–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS).The GPS receiver interfaced to CSM 1 is used as the primary timingreference and synchronizes the entire cellular system. CSM 2 providesclock syncronization back–up, but does not have a GPS receiver.The BTS may be equipped with a LORAN–C Low Frequency Receiver(LFR), a High Stability Oscillator (HSO), or external 10 MHz Rubidiumsource which the CSM can use as a secondary timing reference. In allcases, the CSM monitors and determines what reference to use at a giventime.For RF–GPS, verify the CSM configured with the GPSreceiver “daughter board” is installed in the frame’s CSM 1slot before continuing.IMPORTANT*Follow the steps outlined in Table 3-17 to enable the CSMs installed inthe SCCP shelves.Table 3-17: Enable CSMsStep Action1NOTEIf equipped with two CSMs, enable CSM–2 first.Click on the target CSM.From the Device pull down, select Enable.2A status report is displayed confirming change in the device(s) status.Click OK to close the status report window.NOTESCSM 1 houses the GPS receiver.

The DOD periodically alters satellite orbits;therefore, satellite trajectories are subject to change. A GPS receiver that is INS contains an “almanac”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 “almanac” 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).3NOTESIf equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should bedark green(INS–STB)SIf more than an hour has passed, refer to CSM Verification, see Figure 3-13 and Table 3-20 todetermine the cause.After the 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). Enable MCCsThis procedure configures the MCC and sets the “tx fine adjust”parameter. The “tx fine adjust” parameter is not a transmit gain setting,but a timing adjustment that compensates for the processing delay in theBTS (approximately 3 mS).Follow the steps outlined in Table 3-18 to enable the MCCs installed inthe SCCP shelves.The MGLI and CSM must be downloaded and enabled,prior to downloading and enabling the MCC.IMPORTANT*Table 3-18: Enable MCCsStep Action1Click on the target MCC(s) or from the Select pull down menu choose All MCCs.2From the Device menu, select EnableA status report is displayed confirming change in the device(s) status.3 Click OK to close the status report window. 3
CSM System Time – GPS & LFR/HSO Verification08/01/2001 3-371X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYClock SynchronizationManager (CSM) System TimeThe primary function of the Clock Synchronization Manager (CSM)cards is to maintain CDMA system time. The CSM card in SCCP shelfslot CSM–1 is the primary timing source while the card in slot CSM–2provides redundancy. The second generation CSM card (CSM2) isrequired when using the remote GPS receiver (R–GPS). R–GPS uses aGPS receiver in the antenna head that has a digital output to the CSM2card. A CSM2 card can have a local GPS receiver daughter card tosupport an RF–GPS signal.Each CSM2 card features a temperature–stablized, crystal oscillator thatprovides 19.6608 MHz clock, even second pulse, and 3 MHz referencesignals to the synchronization source selected from the following (referto Table 3-20 for source selection/verification procedures):SGPS: local/RF–GPS or remote/R–GPSSLORAN–C Low Frequency Receiver (LFR) or High StabilityOscillator (HSO)SExternal reference oscillator sourcesCDMA Clock Distribution Cards (CCDs) buffer and distributeeven–second reference and 19.6608 MHz clock signals from the CSMcards. CCD 1 is married to the card in slot CSM–1, and CCD 2 ismarried to the card in slot CSM–2.The BTS switches between the primary and redundant units (card slotsCSM–1 and CSM–2, respectively) upon failure or command. A failurein CSM–1 or CCD 1 will cause the system to switch to theCSM–2–CCD 2 redundant card pair.Fault management has the capability of switching between the GPSsynchronization source and the LFR/HSO backup source in the event ofa GPS receiver failure in CSM–1. During normal operation, the card inCSM–1 selects GPS as the primary timing source (Table 3-20). Thesource selection can also be overridden via the CDMA LMF or by thesystem software.In addition to providing GPS synchronization to the LFR or HSOback–up sources, synchronization between the primary and redundantCSM–CCD pairs increases reliability.Low Frequency Receiver/High Stability OscillatorThe CSM performs the overall configuration and status monitoringfunctions of the LFR/HSO. In the event of GPS failure, the LFR/HSO iscapable of maintaining synchronization initially established by the GPSreference signal.The LFR requires an active external antenna to receive LORAN–C RFsignals. Timing pulses are derived from this signal, which is3
CSM System Time – GPS & LFR/HSO Verification – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-38synchronized to Universal Time Coordinates (UTC) and GPS time. TheLFR can maintain system time indefinately after initial GPS lock.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 lock.Upgrades and Expansions: LFR2/HSO2/HSOXLFR2/HSO2 (second generation cards) both export a timing signal to theexpansion or logical BTS frames. The associated expansion or logicalframes require an HSO–expansion (HSOX) whether the starter frame hasan LFR2 or an HSO2. The HSOX accepts input from the starter frameand interfaces with the CSM cards in the expansion frame. LFR andLFR2 use the same source code in source selection (Table 3-20). HSO,HSO2, and HSOX use the same source code in source selection(Table 3-20).Allow the base site and test equipment to warm up for60 minutes after any interruption in oscillator power. CSMcard warm-up allows the oscillator oven temperature andoscillator frequency to stabilize prior to test. Testequipment warm-up allows the Rubidium standardtimebase to stabilize in frequency before any measurementsare made.NOTE3

Failure to do so canintroduce measurement errors, resulting in incorrectmeasurements and degradation to system performance.Motorola recommends repeating cable calibration beforetesting at each BTS site.CAUTIONCalibration of the communications test set (or equivalenttest equipment) must be performed at the site beforecalibrating the overall test set. Calibrate the test equipmentafter it has been allowed to warm–up and stabilize for aminimum of 60 minutes.IMPORTANT*PurposeThese procedures access the CDMA LMF automated calibration routineused to determine the path losses of the supported communicationsanalyzer, power meter, associated test cables, and (if used) antennaswitch that make up the overall calibrated test equipment set.

Calibrating Cables – OverviewThe cable calibration function is used to measure the loss (in dB) for theTX and RX cables that are to be used for testing. A CDMA analyzer isused to measure the loss of each cable configuration (TX cableconfiguration and RX cable configuration). The cable calibrationconsists of the following steps.SMeasure the loss of a short cable. This is done to compensate for anymeasurement error of the analyzer. The short cable, which is used onlyfor the calibration process, is used in series with both the TX and RXcable configuration when they are measured. The measured loss of theshort cable is deducted from the measured loss of the TX and RXcable configuration to determine the actual loss of the TX and RXcable configurations. This deduction is done so any error in theanalyzer measurement will be adjusted out of both the TX and RXmeasurements.SThe short cable plus the RX cable configuration loss is measured. TheRX cable configuration normally consists only of a coax cable withtype–N connectors that is long enough to reach from the BTS RX portthe test equipment. For BTSs with antenna ports carrying duplexed TXand RX, a directional coupler and, if required by BTS type, anadditional attenuator are also used on the RX cable configuration andmust be included in the measurement.SThe short cable plus the TX cable configuration loss is measured. TheTX cable configuration normally consists of two coax cables withtype–N connectors and a directional coupler, a load, and an additionalattenuator if required by the BTS type. The total loss of the path loss3

Bay Level Offset CalibrationPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-64IntroductionCalibration compensates for normal equipment variations within theBTS and assures maximum measurement accuracy.RF Path Bay Level OffsetCalibrationBay Level Offset (BLO) calibration identifies the accumulated gain inevery transmit path (BBX2 slot) at the BTS site and stores that value inthe CDMA LMF CAL file. The BLOs are subsequently downloaded toeach BBX2.Each transmit path starts at an SCCP shelf backplane BBX2 slot, travelsthrough the CIO card, trunking module, LPA, trunking module (again),TX filter or TX filter combiner, DRDC or TRDC, and ends at a BTS TXantenna port.Each receive path starts at a BTS RX antenna port, travels through aDRDC or TRDC, the MPC card, the CIO card, and terminates at abackplane BBX2 slot.Calibration identifies the accumulated gain in every transmit path ( byBBX2 slot) at the BTS site and stores that value in the CAL file. Whenthe TX path calibration is performed, the RX path BLO willautomatically be set to the default value.When to Calibrate BLOs Calibration of BLOs is required after initial BTS installation.The BLO data of an operational BTS site must be re-calibrated onceeach year. Motorola recommends re-calibrating the BLO data for allassociated RF paths after replacing any of the following components orassociated interconnecting RF cabling:SBBX2 boardSSCCP shelfSCIO cardSCIO–to–LPA trunking module RF cableSLPA trunking moduleSLPASTrunking module–to–TX filter/filter combiner RF cableSTX filter or TX filter combinerSTX filter/filter combiner–to–DRDC/TRDC cableSDRDC or TRDC3

The proper functionof each RF path is verified during calibration. The external testequipment is used to validate/calibrate the TX paths of the BTS.Before installing any test equipment directly to any TXOUT connector you must first verify that there are noCDMA channels keyed. Have the OMC–R place the sectorassigned to the LPA under test OOS. Failure to do so canresult in serious personal injury and/or equipment damage.WARNINGAlways wear a conductive, high impedance wrist strapwhile handling any circuit card/module. If this is not done,there is a high probability that the card/module could bedamaged by ESD.CAUTIONAt new site installations, to facilitate the complete test ofeach SCCP shelf (if the shelf is not already fully populatedwith BBX2 boards), move BBX2 boards from shelvescurrently not under test and install them into the emptyBBX2 slots of the shelf currently being tested to insure thatall BBX2 TX paths are tested.–This procedure can be bypassed on operational sitesthat are due for periodic optimization.–Prior to testing, view the CDF file to verify thecorrect BBX2 slots are equipped. Edit the file asrequired to include BBX2 slots not currentlyequipped (per Systems Engineering documentation).IMPORTANT*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 routine. Functionality is verifiedduring Frame Erasure Rate (FER) testing.3
Bay Level Offset Calibration – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-66BLO Calibration Data FileDuring the calibration process, the CDMA LMF creates a calibration(CAL) data file where BLO values are stored. After calibration has beencompleted, this offset data must be downloaded to the BBX2s using theCDMA LMF Download BLO function. An explanation of the file isshown below.Due to the size of the file, Motorola recommends printingout a copy of a bts.cal file and referring to it for thefollowing descriptions.NOTEThe CAL file is subdivided into sections organized on a per–slot basis (aslot Block).The Slot 1 Block contains the calibration data for the six BBX2 slots.The Slot 20 Block contains the calibration data for the redundant BBX2(see Table 3-32). Each BBX2 slot Block header contains:SA creation Date and Time – broken down into separate parameters ofcreateMonth, createDay, createYear, createHour, and createMin.SThe number of calibration entries – fixed at 720 entries correspondingto 360 calibration points of the CAL file – plus the slot Block format.Within the slot Block body, the BBX2 calibration data (BayLevelCal) isorganized as a large flat array. The array is organized by branch, BBX2SCCP cage slot, and calibration point.SThe first breakdown of the array indicates which branch the containedcalibration points are for. The array covers transmit, main receive, anddiversity receive offsets as follows:Table 3-31: BLO BTS.cal file Array Branch AssignmentsRange Branch AssignmentC[1]–C[120] TransmitC[121]–C[240] No SC4812ET Lite BLO calpoint entries (default only)C[241]–C[360] ReceiveC[361]–C[480] No SC4812ET Lite BLO calpoint entries (default only)C[481]–C[600] Diversity ReceiveC[601]–C[720] No SC4812ET Lite BLO calpoint entries (default only)3

It can be seen thatthere is one BBX2 slot per sector, and 10 calibration points for eachBBX2 (sector) are supported for each branch. Each “calibration point”consists of two entries.SThe first entry for a calibration point (all odd entries) identifies theCDMA channel (frequency) where the BLO is measured. The secondcalibration point entry (all even entries) is the power set level(PwrLvlAdj). The valid range for PwrLvlAdj is from 2500 to 275003

If less than 10 points(frequencies) are calibrated, the BLO data for the highest frequencycalibrated is written into the remainder of the 10 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”In the example above, BLO was measured at only two frequencies(channels 384 and 777) for SCCP slot BBX–1 transmit (Table 3-32).The BLO data for the highest frequency measured (777) will bewritten to the remaining eight transmit calibration points (defined byentries C[5] through C[20]) for BBX2–1.SWhen BLO data is downloaded to the BBXs, the data is downloadedto the devices in the order it is stored in the CAL file. TxCal data(C[1] – C[60]) is sent first. BBX2 slot 1’s 10 calibration points (C[1]– C[20]) are sent initially, followed by BBX2 slot 2’s 10 calibrationpoints (C[21] – C[40]), and so on. The RxCal data is sent next,followed by the RxDCal data.STemperature compensation data (TempLevelCal) is also stored in theCAL file for each slot Block.Test Equipment Setup:RF Path CalibrationFollow the steps outlined in Table 3-33 and refer as needed toFigure 3-15 or Figure 3-16 to set up test equipment.Table 3-33: Set Up Test Equipment (RF Path Calibration)Step Action1If it has not already been done, refer to the procedure in Table 3-6 to interface the CDMA LMFcomputer terminal to the frame LAN A connector.2If it has not already been done, refer to Table 3-7 to start a GUI LMF session.3If required, calibrate the test equipment per the procedure in Table 3-25.3

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.4For TX path calibration, verify that the coaxial cable from the appropriate ANTENNA connector(Figure 1-6 or Figure 1-7) is connected to the test equipment RF input port via the directionalcoupler.Transmit (TX) Path CalibrationThe assigned channel frequency and desired power level at the frame TXports for transmit calibration are derived from the BTS CDF file. EachBBX2 at the site is assigned to a sector and carrier. These are specifiedrespectively in the sector and carrier fields of the ParentCARRIERparameter in each BBX2’s 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 BBX2 is assigned.The calibration procedure attempts to adjust the measured power towithin +0.5 dB of the desired power. The calibration will pass if theerror is less than +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 BBX2and the measured power at the TX port. BLO is derived by deducting theknown BBX2 power output from the power measured at the TX port or(Measured Power) – (BBX2 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 gainThe CDMA LMF Tests menu list items TX Calibration and AllCal/Audit perform TX BLO Calibration testing for installed BBX(s).The All Cal/Audit menu item initiates a series of actions to perform TXcalibration, download BLO, and perform TX audit if the TX calibrationpasses. The TX Calibration selection performs only the TX calibration.When the TX Calibration selection is used, BLO download and TXaudit must be performed as separate activities. All measurements aremade through the appropriate antenna connector using the calibrated TXcable setup.In both the TX Calibration and All Cal/Audit dialog boxes, a VerifyBLO checkbox is provided and checked by default. After the actual TXcalibration is completed during either the TX Calibration or AllCal/Audit process, the BLO derived from the calibration is compared toa standard, acceptable BLO tolerance for the BTS. In some installations,3
Bay Level Offset Calibration – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-70additional items may be installed in the transmit path. The additionalchange in gain from these items could cause BLO verification failureand, therefore, failure of the entire calibration. In these cases, either theVerify BLO checkbox should be unchecked or the additional path lossesshould be added into each applicable sector using the Util > Edit > TXCoupler Loss... function.PrerequisitesBefore running this test, ensure that the following have been done:SCSM–1, GLIs, MCCs, and BBX2s have correct code load and dataload.SPrimary CSM and MGLI are INS.SAll BBX2s are OOS_RAM.STest equipment and test cables are calibrated and connected for TXBLO calibration.SLMF is logged into the BTS in the GUI environment.Connect the test equipment as shown in Figure 3-15 and Figure 3-16and follow the procedure in Table 3-34 to perform the TX calibrationtest.Before installing any test equipment directly to any TXOUT connector, first verify there are no CDMA BBX2channels keyed.

RFDS Setup and Calibration – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20013-82RFDS CalibrationThe RFDS Calibration option is used to calibrate the RFDS TX and RXpaths. For a TX antenna path calibration the BTS XCVR is keyed at apre–determined power level and the BTS power output level is measuredby the RFDS. The power level is then measured at the TX antennadirectional coupler by the power measuring test equipment item beingused (power meter or analyzer). The difference (offset) between thepower level at the RFDS and the power level at the TX antennadirectional coupler is used as the TX RFDS calibration offset value.For an RX antenna path calibration the RFDS is keyed at apre–determined power level and the power input level is measured by theBTS XCVR. A CDMA signal at the same power level measured by theBTS XCVR is then injected at the RX antenna directional coupler by theCDMA communications analyzer. The difference (offset) between theRFDS keyed power level and power level measured at the BTS XCVR isthe RFDS RX calibration offset value.The TX and RX RFDS calibration offset values are written to the CALfile.For each RFDS TSIC, the channel frequency is determined at the lowerthird and upper third of the appropriate band using the frequencies listedin Table 3-44.Table 3-44: 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 BBXchannels keyed.

Automated Acceptance Test Procedure – Introduction08/01/2001 4-11X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYIntroductionThe automated Acceptance Test Procedure (ATP) allows Cellular FieldEngineers (CFEs) to run automated acceptance tests on all equipped BTSsubsystem devices using the CDMA LMF GUI environment andsupported test equipment.The operator can choose to save the results of these tests to a report file,from which ATP reports are generated for later printout.Perform the ATP test on out-of-service sectors or sites only. Because alltests are controlled via the CDMA LMF computer using the GPIBinterface from the CDMA LMF computer, only recommended testequipment supported by the CDMA LMF can be used.Before using the LMF, use an editor to view the”CAVEATS” section in the ”readme.txt” file in the c:\wlmffolder for any applicable information.IMPORTANT*The ATP test is to be performed on out-of-service sectorsonly.DO NOT substitute test equipment with other models notsupported by the LMF.IMPORTANT*Refer to Chapter 3 for detailed information on test setconnections for calibrating equipment, cables and other testset components, if required.NOTEThe CFE selects the appropriate ATP tests to run to satisfy customer andregulatory requirements for verifying cell site performance. These testscan be run individually or as one of the following groups:SAll TX: TX tests verify the performance of the BTS transmitelements. These include the GLI2, MCC, BBX2, BDC, and trunkingmodules, the LPAs, and passive components including splitters,combiners, bandpass filter(s), and RF cables.SAll RX: RX tests verify the performance of the BTS receive elements.These include the MPC (for starter frames), , BBX2, MCC, and GLI2modules, and the passive components including RX filter (starterframe only), and RF cables.SAll TX/RX: Executes all TX and RX tests.SFull Optimization: Executes the TX calibration, downloads BLO,and executes the TX audit before running all TX and RX tests.4
Automated Acceptance Test Procedure – Introduction – continuedPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20014-2PrerequisitesBefore attempting to run any ATP tests, all applicable proceduresoutlined in Chapter 3, Optimization/Calibration, must have beencompleted successfully (i.e., code load and BLO calibration).You cannot substitute test equipment with other models notsupported by the CDMA LMF.NOTEBefore attempting to run any ATP tests, ensure the following:SBTS has been optimized and calibrated (see Chapter 3).SLMF is logged into the BTSSCSMs, GLI2s, BBX2s, MCCs and TSU (if the RFDS is installed)have correct code load and data loadSPrimary CSM and GLI2 are INS_ACTSMCCs are INS_ACTSBBX2s are OOS-RAMSBBX2s are calibrated and BLOs are downloadedSTest cables are calibratedSTest equipment is selectedSTest equipment is connected for ATP testsSTest equipment has been warmed up 60 minutes and calibratedSGPIB is onBefore the FER is run, be sure that all LPAs are turnedOFF (circuit breakers pulled) or that all transmitterconnectors are properly terminated.All transmit connectors must be properly terminated for allATP tests.Failure to observe these warnings may result in bodilyinjury or equipment damage.WARNINGTX/RX Antenna ConnectionsRefer to Figure 1-6 or Figure 1-7 for identification of the transmit andreceive antenna connections where measurement are to be taken.Directional couplers for signal sampling by the RFDS, if installed, areintegral to the SC4812ET Lite transmit and receive paths in the DRDCsand TRDCs. As a result, all ATP measurement connections are made atthe antenna connectors on the RF interface panel.4
Acceptance Tests – Test Set Up08/01/2001 4-368P09253A601X SCt4812ET Lite BTS Optimization/ATPPRELIMINARYRequired Test EquipmentThe following test equipment is required:SLMFSPower meter (used with HP8921A/600 and Advantest R3465)SCommunications test setBefore installing any test equipment directly to any TXOUT connector, verify that there are no CDMA channelskeyed.At active sites, have the OMCR/CBSC place the carrierassigned to the LPAs under test OOS. Failure to do so canresult in serious personal injury and/or equipment damage.WARNINGYou must recalibrate the test equipment before using it toperform the TX Acceptance Tests.NOTEAcceptance Test EquipmentSet UpFollow the steps in Table 4-1 to set up test equipment for all tests.Table 4-1: Set Up Test Equipment – TX Output Verify/Control TestsStep Action1If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-6 andFigure 3-10).2If it has not already been done, refer to Table 3-7 to start a GUI LMF session and log into the BTS.3If it has not already been done, refer to Figure 3-17 or Figure 3-18, as applicable for the testequipment being used, to connect test equipment for acceptance testing.* IMPORTANTCDMA LMF–based measurement commands factor in TX test cable loss between the RFM frame andtest equipment. No additional attenuation can be inserted as the additional losses would not befactored in. 4
Abbreviated (All–inclusive) Acceptance TestsPRELIMINARY1X SCt4812ET Lite BTS Optimization/ATP 08/01/20014-4All–inclusive TestsThe all–inclusive acceptance tests are performed from the LMF GUIenvironment. These tests execute various combinations of individualacceptance tests with a single command. This allows verification ofmultiple aspects of BTS performance while minimizing time needed forindividual test set up and initiation.There are three abbreviated acceptance tests which evaluate differentperformance aspects of the BTS. This allows the CFE to select testing tomeet the specific requirements for individual maintenance andperformance verification situations.
