Preparing the LMF – continued Update Antenna Mapping Files Earlier release versions may require the antenna.map file to be updated. There are two antenna mapping files. These are antenna.map and antenna.asu . Follow the steps outlined in Table 3-13 to check the antenna mapping file and update as needed. Table 3-13: Update Antenna Mapping Files Step Action ! CAUTION If you are not familiar with the UNIX vi editor, create a “dummy” CDF file, and practice making changes to it, prior to altering the “real” one. NOTE For more information on file management, creating bts directories, viewing/editing CDF files, refer to LMF Users Guide, Motorola part no. 68P09226A13. View the antenna.map file (see below) and verify the Xcvrs listed in the CDF file (and that are equipped in the BTS) are also listed in the antenna.map file (for both RX and TX tables). Make sure the antenna.map file has enough RX and TX antennas listed to cover the number of sectors indicated by CDF’s SiteConf parameter. Example of Antenna Map File ––– Rx ––– 1:M 2:D 3:M 4:D 5:M 6:D ––– Tx 1:0 2:0 3:0 4:0 5:0 6:0 –– Sec –– :RX1: :RX2: :RX3: :RX4: :RX5: :RX6: ––– –– Sec –– :TX1: :TX2: :TX3: :TX4: :TX5: :TX6: ––––– Xcvrs ––––– :1,4,5,8 :1,4,5,8 :2,4,6,8 :2,4,6,8 :3,4,7,8 :3,4,7,8 ––––– Xcvrs ––––– :1,4 :2,4 :3,4 :5,8 :6,8 :7,8 Verify all RX and TX antennas listed in the file antenna.map are also listed in the antenna.asu file. NOTE Make edits to the antenna.map and antenna.asu . files as required (using the vi editor). The The antenna.asu file is required only if the BTS is equipped with RFDS. Be sure that the information in antenna files matches your actual configuration. 3-30 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Using CDMA LMF Basic LMF Operation NOTE The terms “CDMA LMF” and “WinLMF” are interchangeable The CDMA LMF allows the user to work in the two following operating environments which are accessed using the specified desktop icon: Graphical User Interface (GUI) using the WinLMF icon Command Line Interface (CLI) using the WinLMF CLI icon The GUI is the primary optimization and acceptance testing operating environment. The CLI environment provides additional capability to the user to perform manually controlled acceptance tests and audit the results of optimization and calibration actions. Basic operation of the LMF GUI includes the following: Selecting and deselecting BTS devices Enabling devices Disabling devices Resetting devices Obtaining device status Sorting a status report window For detailed information on performing these and other LMF operations, refer to the CDMA LMF Operator’s Guide, 68P64114A78. Basic LMF Operation Both the GUI and the CLI use a program known as the handler. Only one handler can be running at one time. The architectural design is such that the GUI must be started before the CLI if you want the GUI and CLI to use the same handler. When the CLI is launched after the GUI, the CLI automatically finds and uses an in–progress login session with a BTS initiated under the GUI. This allows the use of the GUI and the CLI in the same BTS login session. If a CLI handler is already running when the GUI is launched (this happens if the CLI window is already running when the user starts the GUI, or if another copy of the GUI is already running when the user starts the GUI), a dialog window displays the following warning message: The CLI handler is already running. This may cause conflicts with the LMF. Are you sure that you want to start the application? This window also contains yes and no buttons. Selecting yes starts the application. Selecting no terminates the application. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-31 Using CDMA LMF – continued CLI Format Conventions The CLI command can be broken down in the following way: Verb Device including device identifier parameters Switch Option parameters consisting of: – Keywords – Equals sign (=) between the keyword and the parameter value – Parameter values Spaces are required between the verb, device, switch, and option parameters. A hyphen is required between the device and its identifiers. Following is an example of a CLI command. measure bbx–– rssi channel=6 sector=5 Refer to the LMF CLI Commands (68P09251A59) for a complete explanation of the CLI commands and their usage. Logging into a BTS IMPORTANT Be sure that the correct bts–#.cdf and cbsc–#.cdf file is used for the BTS. These should be the CDF files that are provided for the BTS by the CBSC. Failure to use the correct CDF files can result in wrong results. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site. Logging into a BTS establishes a communications link between the BTS and the CDMA LMF. You may be logged into one or more BTS’s at a time, but only one LMF may be logged into each BTS. Before attempting to log into the BTS, confirm the CDMA LMF is properly connected to the BTS (see Figure 3-4). Follow the procedure in Table 3-14 to log into a BTS. Prerequisites Before attempting to login to a BTS, ensure the following have been completed: The LMF is correctly installed and prepared. A bts-nnn folder with the correct CDF and CBSC file exists. The LMF is correctly installed and prepared, and the LMF computer was connected to the BTS before starting the Windows operating system and LMF software. If necessary, restart the computer after connecting it to the BTS (see Table 3-6 and Figure 3-4). 3-32 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Using CDMA LMF – continued BTS Login from the GUI Environment Follow the procedures in Table 3-14 to log into a BTS when using the GUI environment Table 3-14: BTS GUI Login Procedure Step Action Start the LMF GUI environment by double clicking on the WinLMF desktop icon (if the LMF’s not running). NOTE If a warning similar to the following is displayed, select No, shut down other LMF sessions which may be running, and start the LMF GUI environment again: The CLI handler is already running. This may cause conflicts with the LMF Are you sure you want to start the application? Yes No Click on Login tab (if not displayed). If no base stations are displayed in the Available Base Stations pick list, double click on the CDMA icon. Click on the desired BTS number. Click on the Network Login tab (if not already in the forefront). Enter correct IP address (normally 128.0.0.2 for a field BTS) if not correctly displayed in the IP Address box.

(A BTS tab with the BTS is displayed.) NOTE If you attempt to log in to a BTS that is already logged on, all devices will be gray. There may be instances where the BTS initiates a log out due to a system error (i.e., a device failure). If the MGLI is OOS_ROM (blue), it will have to be downloaded with code before other devices can be seen. If the MGLI is OOS–RAM (yellow), it must be enabled before other installed devices can be seen. 3-34 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Using CDMA LMF – continued BTS Login from the CLI Environment Follow the procedures in Table 3-15 to log into a BTS when using the GUI environment Table 3-15: BTS CLI Login Procedure Step Action Double click the WinLMF CLI desktop icon (if the LMF CLI environment is not already running). NOTE If a BTS was logged into under a GUI session when the CLI environment was started, the CLI session will be logged into the same BTS, and step 2 is not required. At the /wlmf prompt, enter the following command: login bts– host= port= where: host = MGLI card IP address (defaults to address last logged into for this BTS or 128.0.0.2 if this is first login to this BTS). port = IP port of the TS (defaults to port last logged into for this BTS or 9216 if this is first login to this BTS) Logging Out Logging out of a BTS is accomplished differently for the GUI and the CLI operating environments. IMPORTANT The GUI and CLI environments use the same connection to a BTS. If a BTS is logged into in both the GUI and the CLI environments at the same time, logging out of the BTS in either environment will log out of it for both. When either a login or logout is performed in the CLI window, there is no GUI indication that the login or logout has occurred. Logging Out of a BTS from the GUI Environment Follow the procedure in Table 3-16 to logout of a BTS when using the GUI environment. Table 3-16: BTS GUI Logout Procedure Step Action Click on the BTS tab menu bar.

Enable CSMs Each BTS CSM system features two CSM boards per site. In a typical operation, the primary CSM locks its Digital Phase Locked Loop (DPLL) circuits to GPS signals. These signals are generated by either an 3-42 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Download the BTS – continued on–board GPS module (RF–GPS) or a remote GPS receiver (R–GPS). The CSM2 card is required when using the R–GPS. The GPS receiver (mounted on CSM 1) is used as the primary timing reference and synchronizes the entire cellular system. CSM 2 provides redundancy (but does not have a GPS receiver). The BTS may be equipped with a LORAN–C LFR, HSO, or external 10 MHz Rubidium source which the CSM can use as a secondary timing reference. The HSOX is used for expansion frames. In all cases, the CSM monitors and determines what reference to use at a given time. IMPORTANT For RF–GPS, verify the CSM configured with the GPS receiver “daughter board” is installed in the frame’s CSM 1 slot before continuing. Follow the steps outlined in Table 3-23 to enable the CSMs installed in the C–CCP shelves. Table 3-23: Enable CSMs Step Action Click on the target CSM. From the Device pull down, select Enable. NOTE If equipped with two CSMs, enable CSM–2 first A status report is displayed confirming change in the device(s) status. Click OK to close the status report window. NOTE FAIL may be shown in the status table for enable action. If Waiting For Phase Lock is shown in the Description field, the CSM changes to the Enabled state after phase lock is achieved. CSM 1 houses the GPS receiver. The enable sequence can take up to one hour (see below). * IMPORTANT The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and operated by the United States Department of Defense (D.O.D.). The D.O.D. 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 GPS receiver “almanac” to be updated. Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position fix for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS receiver needs to track only one satellite, depending on accuracy mode set during the data load). . . . continued on next page Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-43 Download the BTS – continued Table 3-23: Enable CSMs Step Action NOTE If equipped with two CSMs, CSM–1 should be bright green (INS–ACT) and CSM–2 should be dark green (INS–STY) If more than an hour has passed, refer to CSM Verification, see Figure 3-8 and Table 3-26 to determine the cause. NOTE After the CSMs have been successfully enabled, observe the PWR/ALM LEDs are steady green (alternating green/red indicates the card is in an alarm state). Enable MCCs This 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 the BTS (approximately 3 mS). Follow the steps outlined in Table 3-24 to enable the MCCs installed in the C–CCP shelves. IMPORTANT The MGLI and CSM must be downloaded and enabled, before downloading and enabling the MCC. Table 3-24: Enable MCCs Step Action Click on the target MCC(s) or from the Select pull down menu choose MCCs. From the Device menu, select Enable A status report is displayed confirming change in the device(s) status. Click OK to close the status report window. 3-44 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 CSM System Time – GPS & LFR/HSO Verification Clock Synchronization Manager System Time The primary function of the Clock Synchronization Manager (CSM) boards (slots 1 and 2) is to maintain CDMA system time. The CSM in slot 1 is the primary timing source while slot 2 provides redundancy. The CSM2 card (CSM second generation) is required when using the remote GPS receiver (R–GPS). R–GPS uses a GPS receiver in the antenna head that has a digital output to the CSM2 card. CSM2 can have a daughter card as a local GPS receiver to support an RF–GPS signal. The CSM2 switches between the primary and redundant units (slots 1 and 2) upon failure or command. CDMA Clock Distribution Cards (CCDs) buffer and distribute even–second reference and 19.6608 MHz clocks. CCD 1 is married to CSM 1 and CCD 2 is married to CSM 2. A failure on CSM 1 or CCD 1 cause the system to switch to redundant CSM 2 and CCD 2. Each CSM2 board features an ovenized, crystal oscillator that provides 19.6608 MHz clock, even second pulse, and 3 MHz referenced to the selected synchronization source (see Table 3-26): GPS: local/RF–GPS or remote/R–GPS LORAN–C Frequency Receiver (LFR) or High Stability Oscillator (HSO) External reference oscillator sources Fault management has the capability of switching between the GPS synchronization source and the LFR/HSO backup source in the event of a GPS receiver failure on CSM 1. During normal operation, the CSM 1 board selects GPS as the primary source (see Table 3-26). The source selection can also be overridden via the LMF or by the system software. Synchronization between the primary and redundant CSM CCD pairs, as well as the LFR or HSO back–up to GPS synchronization, increases reliability. LFR/HSO The CSM handles the overall configuration and status monitoring functions of the LFR/HSO. In the event of GPS failure, the LFR/HSO is capable of maintaining synchronization initially established by the GPS reference signal. The LFR requires an active external antenna to receive LORAN RF signals. Timing pulses are derived from this signal, which is synchronized to Universal Time Coordinates (UTC) and GPS time. The LFR can maintain system time indefinately after initial GPS lock. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-45 CSM System Time – GPS & LFR/HSO Verification – continued The HSO is a high stability 10 MHz oscillator with the necessary interface to the CSMs. The HSO is typically installed in those geographical areas not covered by the LORAN–C system. Since the HSO is a free–standing oscillator, system time can only be maintained for 24 hours after 24 hours of GPS lock. Upgrades and Expansions: LFR2/HSO2/HSOX LFR2/HSO2 (second generation cards) both export a timing signal to the expansion frames. The associated expansion frames require an HSO–expansion (HSOX) whether the starter frame has an LFR2 or an HSO2. The HSOX accepts input from the starter frame and interfaces with the CSM cards in the expansion frame. LFR and LFR2 use the same source code in source selection (see Table 3-26). HSO, HSO2, and HSOX use the same source code in source selection (see Table 3-26). NOTE Allow the base site and test equipment to warm up for 60 minutes after any interruption in oscillator power. CSM board warm-up allows the oscillator oven temperature and oscillator frequency to stabilize prior to test. Test equipment warm-up allows the Rubidium standard timebase to stabilize in frequency before any measurements are made. 3-46 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 CSM System Time – GPS & LFR/HSO Verification – continued CSM Frequency Verification The objective of this procedure is the initial verification of the CSM boards before performing the RF path verification tests. Parts of this procedure will be repeated for final verification after the overall optimization has been completed. Test Equipment Setup (GPS & LFR/HSO Verification) Follow the steps outlined in Table 3-25 to set up test equipment. Table 3-25: Test Equipment Setup (GPS & LFR/HSO Verification) Step Action 1a For local GPS (RF–GPS): Verify a CSM board with a GPS receiver is installed in primary CSM slot 1 and that CSM–1 is INS. NOTE This is verified by checking the board ejectors for kit number SGLN1145 on the board in slot 1. 1b For Remote GPS (RGPS):Verify a CSM2 board is installed in primary slot 1 and that CSM–1 is INS. NOTE This is verified by checking the board ejectors for kit number SGLN4132ED or later. Remove CSM–2 (if installed) and connect a serial cable from the LMF COM 1 port (via null modem board) to the MMI port on CSM–1 (see Figure 3-8). Reinstall CSM–2. Start an MMI communication session with CSM–1 by using the Windows desktop shortcut icon (see Table 3-5) NOTE The LMF program must be running when a Hyperterminal session is started. When the terminal screen appears press the Enter key until the CSM> prompt appears. CAUTION Connect GPS antenna to the (GPS) RF connector ONLY.

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.) This procedure must be performed prior to beginning the optimization. Verify all test equipment (including all associated test cables and adapters actually used to interface all test equipment and the BTS) has been calibrated and maintained as a set. CAUTION If any piece of test equipment, test cable, or RF adapter, that makes up the calibrated test equipment set, has been replaced, re-calibration must be performed. Failure to do so can introduce measurement errors, resulting in incorrect measurements and degradation to system performance. IMPORTANT Calibration of the communications test set (or equivalent test equipment) must be performed at the site before calibrating the overall test set. Calibrate the test equipment after it has been allowed to warm–up and stabilize for a minimum of 60 minutes. Purpose These procedures access the CDMA LMF automated calibration routine used to determine the path losses of the supported communications analyzer, power meter, associated test cables, and (if used) antenna switch that make up the overall calibrated test set. After calibration, the gain/loss offset values are stored in a test measurement offset file on the CDMA LMF. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-73 Test Set Calibration – continued GPIB Addresses GPIB addresses can range from 1 through 30. The LMF will accept any address in that range, but the numbers entered in the LMF Options window GPIB address box must match the addresses of the test equipment. Motorola recommends using 1 for a CDMA signal generator, 13 for a power meter, and 18 for a communications system analyzer. To verify and, if necessary, change the GPIB addresses of the test equipment, refer to the Setting GPIB Addresses section of Appendix F. Selecting Test Equipment Use LMF Options from the Options menu list to select test equipment automatically (using the autodetect feature) or manually. Prerequisites 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 CDMA LMF computer via a GPIB box (normal setup). The Network Connection tab is used when the test equipment is to be connected remotely via a network connection. Ensure the following has been completed before selecting test equipment: Test equipment is correctly connected and turned on. CDMA LMF computer serial port and test equipment are connected to the GPIB box. Manually Selecting Test Equipment in a Serial Connection Tab Test equipment can be manually specified before, or after, the test equipment is connected. CDMA LMF does not check to see if the test equipment is actually detected for manual specification. Table 3-30: Selecting Test Equipment Manually in a Serial Connection Tab Step Action From the Tools menu, select Options. The LMF Options window appears. Click on the Serial Connection tab (if not in the forefront). Select the correct serial port in the COMM Port pick list (normally COM1). Click on the Manual Specification button (if not enabled). Click on the check box corresponding to the test item(s) to be used. 3-74 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Test Set Calibration – continued Table 3-30: Selecting Test Equipment Manually in a Serial Connection Tab Step Action Type the GPIB address in the corresponding GPIB address box (refer to the Setting GPIB Addresses section of Appendix F for directions on verifying and/or changing test equipment GPIB addresses). Motorola–recommended addresses are: 1 = signal generator 13 = power meter 18 = communications system analyzer * IMPORTANT When test equipment items are manually selected by the operator, the LMF defaults to using a power meter for RF power measurements. The LMF will use a communications system analyzer for RF power measurements only if a power meter is not selected (power meter checkbox not checked). Click on Apply. (The button will darken until the selection has been committed.) Click on Dismiss to close the test equipment window. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-75 Test Set Calibration – continued Automatically Selecting Test Equipment in a Serial Connection Tab When using the auto-detection feature to select test equipment, the CDMA LMF examines which test equipment items are actually communicating with CDMA LMF. Follow the procedure in Table 3-31 to use the auto-detect feature. Table 3-31: Selecting Test Equipment Using Auto-Detect Step Action From the Tools menu, select Options. The LMF Options window appears. Click on the Serial Connection tab (if not in the forefront). Select the correct serial port in the COMM Port pick list (normally COM1). Click on Auto–Detection (if not enabled). Type in the GPIB addresses in the box labeled GPIB address to search (if not already displayed). NOTE Refer to the Setting GPIB addresses section of Appendix F for instructions on verifying or changing test equipment GPIB addresses, if necessary. When both a power meter and analyzer are selected, the first item listed in the GPIB addresses to search box will be used for RF power measurements (i.e., TX calibration). The address for a signal generator is normally 1, a power meter is normally 13 and the address for a CDMA analyzer is normally 18. If 1, 13,18 are included in the GPIB addresses to search box, the power meter (13) will be used for RF power measurements. If the test equipment items are manually selected the CDMA analyzer is used only if a power meter is not selected. Click Apply. The button will darken until the selection has been committed. A check mark will appear in the Manual Configuration section for detected test equipment items. Click Dismiss to close the LMF Options window. 3-76 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 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. Calibrate Test Equipment from the Util menu list is used to calibrate test equipment item before being used for testing. The test equipment must be selected before beginning calibration. Follow the procedure in Table 3-32 to calibrate the test equipment. Table 3-32: Test Equipment Calibration Step Action From the Util menu, select Calibrate Test Equipment. A Directions window is displayed. Follow the instructions provided. Follow the direction provided. Click on Continue to close the Directions window. A status window is displayed. Click on OK to close the status report window. Calibrating Cables The cable calibration function is used to measure the loss (in dB) for the TX and RX cables that are to be used for testing. A CDMA analyzer is used to measure the loss of each cable configuration (TX cable configuration and RX cable configuration). The cable calibration consists of the following procedures. Measure the loss of a short cable. This is done to compensate for any measurement error of the analyzer. The short cable, which is used only for the calibration process, is used in series with both the TX and RX cable configuration when they are measured. The measured loss of the short cable is deducted from the measured loss of the TX and RX cable configuration to determine the actual loss of the TX and RX cable configurations. This deduction is done so any error in the analyzer measurement will be adjusted out of both the TX and RX measurements. Measure the short cable plus the RX cable configuration loss is measured. The RX cable configuration normally consists only of a coax cable with type–N connectors that is long enough to reach from the BTS RX port the test equipment. Measure 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 BTS type. The total loss of the path loss of the TX cable configuration must be as required for the BTS (normally 30 or 50 dB). The Motorola Cybertest analyzer is different in that the required attenuation/load is built into the test set so the TX cable configuration consists only of the required length coax cable. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-77 Test Set Calibration – continued Calibrating Cables with a CDMA Analyzer The Cable Calibration menu item from the Util menu list is used to calibrate both TX and RX test cables for use with CDMA LMF. NOTE LMF cable calibration cannot be accomplished with an HP8921A analyzer for 1.9 MHz. A different analyzer type or the signal generator and spectrum analyzer method must be used (refer to Table 3-34 and Table 3-35). Cable calibration values must be manually entered if the signal generator and spectrum analyzer method is used. For the HP8921A, refer to Appendix F. The test equipment must be selected before this procedure can be started. Follow the procedure in Table 3-33 to calibrate the cables. Table 3-33: Cable Calibration Step Action From the Util menu, select Cable Calibration. A Cable Calibration window is displayed. Enter a channel number(s) in the Channels box. Multiple channels numbers must be separated with a comma, no space (i.e., 200,800). When two or more channels numbers are entered, the cables will be calibrated for each channel. Interpolation will be accomplished for other channels as required for TX calibration. Select TX and RX CABLE CAL, TX CABLE CAL or RX CABLE CAL in the Cable Calibration picklist. Click OK. Follow the directions displayed for each step. A status report window will be displayed with the results of the cable calibration. 3-78 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Test Set Calibration – continued Calibrating TX Cables Using a Signal Generator and Spectrum Analyzer Follow the procedure in Table 3-34 to calibrate the TX cables using the signal generator and spectrum analyzer. Refer to Figure 3-22 for a diagram of the signal generator and spectrum analyzer. Table 3-34: Calibrating TX Cables Using Signal Generator and Spectrum Analyzer Step Action Connect a short test cable between the spectrum analyzer and the signal generator. Set signal generator to 0 dBm at the customer frequency of 869–894 MHz for 800 MHz CDMA and 1930–1990 MHz band for North American PCS. Use spectrum analyzer to measure signal generator output (see Figure 3-22, “A”) and record the value. Connect the spectrum analyzer’s short cable to point “B”, as shown in the lower portion of the diagram, to measure cable output at customer frequency (869–894 MHz for 800 MHz CDMA and 1930–1990 MHz for North American PCS) and record the value at point “B”. Calibration factor = A – B Example: Cal = –1 dBm – (–53.5 dBm) = 52.5 dB NOTE The short cable is used for calibration only. It is not part of the final test setup. After calibration is completed, do not re-arrange any cables. Use the equipment setup, as is, to ensure test procedures use the correct calibration factor.

RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX. Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX slot. Each transmit path starts at a BBX backplane slot, travels through the LPA, and terminates at a BTS TX antenna port. Calibration identifies the accumulated gain in every transmit path (BBX slot) at the BTS site and stores that value in the CAL file. Each transmit path starts at a C–CCP shelf backplane BBX slot, travels through the LPA, and ends at a BTS TX antenna port. When the TX path calibration is performed, the RX path BLO will automatically 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 once each year. Motorola recommends re-calibrating the BLO data for all associated RF paths after replacing any of the following components or associated interconnecting RF cabling: Jan 2002 BBX board C–CCP shelf CIO card CIO to LPA backplane RF cable LPA backplane LPA TX filter / TX filter combiner TX thru-port cable to the top of frame SC4812ET BTS Optimization/ATP — CDMA LMF 3-83 Bay Level Offset Calibration – continued 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. WARNING Before installing any test equipment directly to any TX OUT connector you must first verify that there are no CDMA channels keyed. Have the OMC–R place the sector assigned to the LPA under test OOS. Failure to do so can result in serious personal injury and/or equipment damage. CAUTION Always wear a conductive, high impedance wrist strap while handling any circuit card/module. If this is not done, there is a high probability that the card/module could be damaged by ESD. IMPORTANT 3-84 At new site installations, to facilitate the complete test of each CCP shelf (if the shelf is not already fully populated with BBX boards), move BBX boards from shelves currently not under test and install them into the empty BBX slots of the shelf currently being tested to insure that all BBX TX paths are tested. – This procedure can be bypassed on operational sites that are due for periodic optimization. – Prior to testing, view the CDF file to verify the correct BBX slots are equipped. Edit the file as required to include BBX slots not currently equipped (per Systems Engineering documentation). SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a calibration (BLO) data file. After calibration has been completed, this offset data must be downloaded to the BBXs 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. The CAL file is subdivided into sections organized on a per slot basis (a slot Block). Slot 1 contains the calibration data for the 12 BBX slots. Slot 20 contains the calibration data for the redundant BBX (see Table 3-39). Each BBX slot header block contains: A creation Date and Time – broken down into separate parameters of createMonth, createDay, createYear, createHour, and createMin. The number of calibration entries – fixed at 720 entries corresponding to 360 calibration points of the CAL file including the slot header and actual calibration data. The calibration data for a BBX is organized as a large flat array. The array is organized by branch, BBX slot, and calibration point. – The first breakdown of the array indicates which branch the contained calibration points are for. The array covers transmit, main receive and diversity receive offsets as follows: Table 3-38: BLO BTS.cal file Array Branch Assignments Jan 2002 Range Assignment C[1]–C[240] Transmit C[241]–C[480] Receive C[481]–C[720] Diversity Receive SC4812ET BTS Optimization/ATP — CDMA LMF 3-85 Bay Level Offset Calibration – continued – The second breakdown of the array is per sector.

As you can see, 10 calibration points per sector are supported for each branch. Two entries are required for each calibration point. The first value (all odd entries) refer to the CDMA channel (frequency) the BLO is measured at. The second value (all even entries) is the power set level. The valid range for PwrLvlAdj is from 2500 to 27500 (2500 corresponds to –125 dBm and 27500 corresponds to +125 dBm). 3-86 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Bay Level Offset Calibration – continued The 20 calibration entries for each slot/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, C[19]=777, C[20]=19086, (since only two cal points were calibrated this would be repeated for the next 8 points) When the BBX is loaded with BLO data, the cal file data for the BBX is downloaded to the device in the order it is stored in the CAL file. TxCal data is sent first, C[1] – C[60]. BBX slot 1’s 10 calibration points are sent (C[1] – C[20]), followed by BBX slot 2’s 10 calibration points (C[21] – C[40]), etc. The RxCal data is sent next, followed by the RxDCal data. Temperature compensation data is also stored in the cal file for each slot. Test Equipment Setup: RF Path Calibration Follow the steps in Table 3-40 to set up test equipment. Table 3-40: Test Equipment Setup (RF Path Calibration) Step Action NOTE Verify the GPIB is properly connected and turned on. ! CAUTION To prevent damage to the test equipment, all transmit (TX) test connections must be via the 30 dB directional coupler for 800 MHz or via a 30 dB coupler with a 20 dB in–line attenuator for 1900 MHz. Connect the LMF computer terminal to the BTS LAN A connector on the BTS (if you have not already done so). Refer to the procedure in Table 3-6. If required, calibrate the test equipment per the procedure in Table 3-32. Connect the test equipment as shown in Figure 3-17, Figure 3-18 and Figure 3-19. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 3-87 Bay Level Offset Calibration – continued Transmit (TX) Path Calibration The assigned channel frequency and power level (as measured at the top of the frame) for transmit calibration is derived from the site CDF file. For each BBX, 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 BBX (located under the ParentSECTOR field of the ParentCARRIER CDF file parameter). The calibration procedure attempts to adjust the power to within +0.5 dB of the desired power. The calibration will pass if the error is less than +1.5 dB. The TX Bay Level Offset at sites WITHOUT the directional coupler option, is approximately 42.0 dB ±3.0 dB. At sites WITHOUT RFDS option, BLO is approximately 42.0 dB ±4.0 dB. A typical example would be TX output power measured at BTS (36.0 dBm) minus the BBX TX output level (approximately –6.0 dBm) would equate to 42 dB BLO. The TX Bay Level Offset at sites WITH the directional coupler option, is approximately 41.4 dB ±3.0 dB. TX BLO = Frame Power Output minus BBX output level. Example: TX output power measured at RFDS TX coupler (39.4 dBm) minus the BBX TX output level (approximately –2.0 dBm) and RFDS directional coupler/cable (approximately –0.6 dBm) would equate to 41.4 dB BLO. The LMF Tests menu list items, TX Calibration and All Cal/Audit, perform the TX BLO Calibration test for a XCVR(s). The All Cal/Audit menu item performs TX calibration, downloads BLO, and performs TX audit if the TX calibration passes. All measurements are made through the appropriate TX output connector using the calibrated TX cable setup. Test Pattern Drop–down Pick List Pilot is shown as the default setting in this pick list box. The full range of available selections and their descriptions are as follows: Standard – performs calibration or audit using pilot, paging, synch, and six traffic channels with IS–97–specified gain. This pattern setting should be used for all non–in–service calibrations and audits. Using this pattern setting requires the selection of both a BBX and at least one MCC. Pilot (default) – performs calibration using only the pilot channel. This pattern setting should be used for in–service calibrations, and requires selection of only a BBX. CDFPilot –This pattern setting is for advanced users. It performs calibration or audit using the CDF value for pilot gain and IS–97 gain values for all the other channels included in the Standard pattern setting (paging, synch, and six traffic). Using this pattern setting requires the selection of both a BBX and at least one MCC. 3-88 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Bay Level Offset Calibration – continued CDF – This pattern setting is for advanced users who need to use CDF gain settings for all channels included in the Standard pattern setting (pilot, paging, synch, and six traffic). Using this pattern setting requires the selection of both a BBX and at least one MCC. Verify BLO In both the TX Calibration and All Cal/Audit dialog boxes, a Verify BLO checkbox is provided and checked by default. After the actual TX calibration is completed during either the TX Calibration or All Cal/Audit process, the BLO derived from the calibration is compared to a standard, acceptable BLO tolerance for the BTS. In some installations, additional items may be installed in the transmit path. The additional change in gain from these items could cause BLO verification failure and, therefore, failure of the entire calibration. In these cases, either the Verify BLO checkbox should be unchecked or the additional path losses should be added into each applicable sector using the Util>Edit>TX Coupler Loss function. Single–Sided BLO Normally valid values are some value plus–or–minus some offset. If single–sided BLO” is selected, the result will only be considered a success if it’s in the lower half of the range. If it was normally success from 37–47 (which is 42± 5), single–sided BLO” would make it a success only if the result was from 37–42. Prerequisites Before running this test, ensure that the following have been done: CSM–1, GLIs, MCCs, and BBXs have correct code load and data load. Primary CSM and MGLI are INS. All BBXs are OOS_RAM.

TX Path Calibration – For a TX antenna path calibration the BTS XCVR is keyed at a pre–determined power level and the BTS power output level is measured by the RFDS. The power level is then measured at the TX antenna directional coupler by the power measuring test equipment item being used (power meter or analyzer). The difference (offset) between the power level at the RFDS and the power level at the TX antenna directional coupler is used as the TX RFDS calibration offset value. RX Path Calibration – For an RX antenna path calibration the RFDS is keyed at a pre–determined power level and the power input level is measured by the BTS BBX. A CDMA signal at the same power level measured by the BTS BBX is then injected at the RX antenna directional coupler by the communications system analyzer. The difference (offset) between the RFDS–keyed power level and power level measured at the BTS BBX is the RFDS RX calibration offset value. RFDS calibration and the CAL file – The TX and RX RFDS calibration offset values are written to the CAL file in the slot[385] Block. TSIC channel frequency – For each RFDS TSIC, the channel frequency is determined at the lower third and upper third of the appropriate band using the frequencies listed in Table 3-51. Table 3-51: RFDS TSIC Calibration Channel Frequencies System Channel Calibration Points 800 MHz (A and B) 341 and 682 1.9 GHz 408 and 791 WARNING Before installing any test equipment directly to any TX OUT connector, verify that there are no CDMA channels keyed.

The results of these tests (at the option of the operator) are written to a file that can be printed. All tests are controlled via the LMF platform using the GPIB interface, therefore, only recommended test equipment supported by the LMF can be used. This chapter describes the tests run from the GUI environment, which is the recommended method. The GUI provides the advantages of simplifying the LMF user interface, reducing the potential for miskeying commmands and associated parameters, and speeding up the execution of complex operations involving multiple command strings. If you feel the command line interface (CLI) will provide additional insight into the progress of ATPs and problems that could possibly be encountered, refer to LMF CLI Commands. IMPORTANT Before using the LMF, use an editor to view the ”CAVEATS” section in the ”readme.txt” file in the c:\wlmf folder for any applicable information. The ATP test is to be performed on out-of-service sectors only. DO NOT substitute test equipment with other models not supported by the LMF. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 4-1 Automated Acceptance Test Procedure – Overview – continued Reduced ATP NOTE Equipment has been factory–tested for FCC compliance. If license–governing bodies require documentation supporting SITE compliance with regulations, a full ATP may be necessary. Perform the Reduced ATP only if reports for the specific BTS site are NOT required. After downloading the proper operational software to the BTS, the Cellular Field Engineer (CFE) must perform these procedures (minimal recommendation): Verify the TX/RX paths by performing TX Calibration, TX Audit and FER tests. Retrieve Calibration Data required for normal site operation. Should failures occur while performing the specified tests, refer to the Basic Troubleshooting section of this manual for help in determining the failure point. Once the point of failure has been identified and corrected, refer to the BTS Optimization and ATP Test Matrix section (Table B-1) to determine the applicable test that must be performed. In the unlikely event that the BTS passes these tests but has a forward link problem during normal operation, the CFE should then perform the additional TX tests for troubleshooting: TX spectral mask, TX rho, and TX code domain. NOTE Refer to Chapter 3 for detailed information on test set connections for calibrating equipment, cables and other test set components, if required. Customer requirements determine which ATP tests to are to be performed and the field engineer selects the appropriate ATP tests to run. The tests can be run individually or as one of the following groups: All TX: TX tests verify the performance of the BTS transmit line up. These include the GLI2, MCC, BBX, and CIO cards, the LPAs and passive components including splitters, combiners, bandpass filter, and RF cables. All RX: RX tests verify the performance of the BTS receiver line up. These includes the MPC (for starter frames), EMPC (for expansion frames), CIO, BBX, MCC, and GLI2 cards and the passive components including RX filter (starter frame only), and RF cables. All TX/RX: Executes all the TX and RX tests. 4-2 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Automated Acceptance Test Procedure – Overview – continued Full Optimization: Executes the TX calibration, download BLO, and TX audit before running all of the TX and RX tests. ATP Test Prerequisites Before attempting to run any ATP tests, ensure the following: BTS has been optimized and calibrated (see Chapter 3). LMF is logged into the BTS. CSMs, GLI2s, BBXs, MCCs and TSU (if the RFDS is installed)have correct code load and data load Primary CSM and GLI2 are INS_ACT MCCs are INS_ACT. BBXs are OOS-RAM. BBXs are calibrated and BLOs are downloaded. Test cables are calibrated. Test equipment is selected. Test equipment is connected for ATP tests. Test equipment has been warmed up 60 minutes and calibrated. GPIB is on. WARNING Before the FER is run, be sure that all LPAs are turned OFF (circuit breakers pulled) or that all transmitter ports are properly terminated. All transmit ports must be properly terminated for all ATP tests. Failure to observe these warnings may result in bodily injury or equipment damage. TX/RX OUT Connections IMPORTANT Jan 2002 Many of the acceptance test procedures require taking measurements at the TX OUT (BTS/RFDS) connector. At sites with RFDS, all measurements are through the RFDS directional coupler TX OUT connector. SC4812ET BTS Optimization/ATP — CDMA LMF 4-3 Automated Acceptance Test Procedure – Overview – continued ATP Test Procedure There are three different ATP testing options that can be performed to completely test a BTS. Depending on your requirements, one of the following ATP testing options should be run. Table 4-1 provides the procedure to execute an ATP test. To completely test a BTS, run the ATP tests according to one of the following ATP testing options. ATP Testing Option 1 All TX/RX test ATP Testing Option 2 All TX test All RX test ATP Testing Option 3 TX Mask test Rho test Pilot Time Offset test Code Domain Power test FER test NOTE The Full Optimization test can be run if you want the TX path calibrated before all the TX and RX tests are run. IMPORTANT If manual testing has been performed with the HP analyzer, remove the manual control/system memory card from the card slot and set the IO CONFIG to the Talk & Listen mode before starting the automated testing. CDMA 2000 Testing Software release 2.16.x supports two new pieces of test equipment. These are the Agilent E4406A with E4432B, as well as the Advantest R3267 with R3562. The E4406A/E4432B pair, or the R3267/R3562 pair, should be connected together using a GPIB cable. This test equipment is capable of performing tests in both IS95 mode as well as cdma2000 mode if the required options are installed: The HP 8935 with option 200 or R2k for 1X TX and with Agilent E4432B Signal Generator for 1X FER 4-4 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 Automated Acceptance Test Procedure – Overview – continued Individual Acceptance Tests The following individual ATP tests can be used to verify the results of specific tests: Spectral Purity TX Mask This test verifies that the transmitted CDMA carrier waveform, generated on each sector, meets the transmit spectral mask specification with respect to the assigned CDF file values. Waveform Quality (rho) This test verifies that the transmitted Pilot channel element digital waveform quality (rho) exceeds the minimum specified value in ANSI–J_STD–019. “Rho” represents the correlation between actual and perfect CDMA modulation spectrum. A rho value of 1.0000 represents 100% (or perfect correlation). Pilot Time Offset The Pilot Time Offset is the difference between the CDMA analyzer measurement interval (based on the BTS system time reference) and the incoming block of transmitted data from the BTS (Pilot only, Pilot Gain = 262, PN Offset = 0). Code Domain Power This test verifies code domain power levels, which have been set for all ODD numbered Walsh channels, using the OCNS command. This is done by verifying that the ratio of PILOT divided by OCNS is equal to 10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF” Walsh channels measures < –27 dB . Frame Error Rate The Frame Error Rate (FER) test verifies RX operation of the entire CDMA Reverse Link using all equipped MCCs assigned to all respective sector/antennas. The test verifies the BTS sensitivity on all traffic channel elements currently configured on all equipped MCCs at an RF input level of –119 dBm (or –116 dBm if using TMPC). Follow the procedure in Table 4-1 to perform any ATP test. NOTE The STOP button can be used to stop the testing process.

SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 TX Spectral Purity Transmit Mask Acceptance Test Background: Tx Mask Test This test verifies the spectral purity of each BBX2 carrier keyed up at a specific frequency, per the current CDF file assignment. All tests are performed using the external calibrated test set, controlled by the same command. All measurements are through the appropriate TX OUT (BTS/RFDS) connector. The Pilot Gain is set to 541 for each antenna and all channel elements from the MCCs are forward-link disabled. The BBX2 is keyed up, using both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot channel element only). BBX2 power output is set to obtain +40 dBm as measured at the TX OUT connector (on either the BTS or RFDS directional coupler). NOTE TX output power is set to +40 dBm by setting BTS power level to +33.5 dBm to compensate for 6.5 dB increase from pilot gain set to 541. The calibrated communications test set measures and returns the attenuation level of all spurious and IM products in a 30 kHz resolution bandwidth with respect to the mean power of the CDMA channel, measured in a 1.23 MHz bandwidth, in dB, verifying that results meet system tolerances at the following test points: 1.9 GHz – at least –45 dB @ + 900 kHz from center frequency – at least –45 dB @ – 900 kHz from center frequency 800 MHz: – – – – at least –45 dB @ + 750 kHz from center frequencY at least –45 dB @ – 750 kHz from center frequency at least –60 dB @ – 1980 kHz from center frequency at least –60 dB @ – 1980 kHz from center frequency The BBX2 then de-keys, and, if selected, the MCC is re-configured to assign the applicable redundant BBX2 to the current TX antenna path under test. The test is then repeated.

All tests are performed using the external calibrated test set controlled by the same command. All measurements are via the appropriate TX OUT (BTS/RFDS) connector. The Pilot Gain is set to 262 for each antenna, and all channel elements from the MCCs will be forward link disabled. The BBX2 is keyed up using both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot channel element only, Walsh code 0). BBX2 power output is set to 40 dBm as measured at the TX OUT connector (on either the BTS or RFDS directional coupler). The calibrated communications test set measures and returns the Pilot channel element digital waveform quality (rho) in dB, verifying that result meets system tolerances Waveform quality (rho) should be > 0.912 (–0.4 dB). The BBX2 then de-keys and the applicable redundant BBX2 is assigned to the current TX antenna path under test. The test is then repeated. The LMF Tests menu list item, Rho, performs the waveform quality test for a XCVR(s). All measurements are made through the appropriate TX output connector using the calibrated TX cable setup. Jan 2002 SC4812ET BTS Optimization/ATP — CDMA LMF 4-9 TX Pilot Time Offset Acceptance Test Background: Pilot Offset Acceptance Test This test verifies the transmitted Pilot channel element Pilot Time Offset of each BBX2 carrier keyed up at a specific frequency per the current CDF file assignment. All tests are performed using the external calibrated test set controlled by the same command. All measurements will be via the appropriate TX OUT (BTS/RFDS) connector. The Pilot Gain is set to 262 for each antenna and all TCH elements from the MCCs are forward link disabled. The BBX is keyed up using both bbxlvl and bay level offsets to generate a CDMA carrier (with pilot channel element only, Walsh code 0). BBX power output is set to 40 dBm as measured at the TX OUT connector (on either the BTS or RFDS directional coupler). The calibrated communications test set measures and returns the Pilot Time Offset in uS, verifying results meet system tolerances: Pilot Time Offset should be within < 3 µs of the target PT Offset (0 mS). The BBX2 then de-keys, and the applicable redundant BBX2 is assigned to the current TX antenna path under test. The test is then repeated. 4-10 SC4812ET BTS Optimization/ATP — CDMA LMF Jan 2002 TX Code Domain Power Acceptance Test Background: Code Domain Power Test This test verifies the Code Domain Power/Noise of each BBX2 carrier keyed up at a specific frequency per the current CDF file assignment. All tests are performed using the external calibrated test set controlled by the same command. All measurements are via the appropriate TX OUT (BTS/RFDS) connector. For each sector/antenna under test, the Pilot Gain is set to 262 and all MCC channel elements under test are configured to generate Orthogonal Channel Noise Source (OCNS) on different odd Walsh codes, and are assigned a full–rate gain of 81. The maximum number of MCC/CEs to be tested an any one time is 32 (32 odd Walsh codes). If more than 32 CEs exist, then multiple sets of measurements are made, so all channel elements are verified on all sectors. BBX2 power output is set to 40 dBm as measured at the TX OUT connector (on either the BTS or RFDS directional coupler). Code domain power levels, which have been set for all ODD numbered Walsh channels, are verified using the OCNS command. This is done by verifying that Pilot Power (dBm) minus OCNS Power (dBm) is equal to 10.2 + 2 dB and that the noise floor of all “OFF” Walsh channels measures < –27 dB (with respect to total CDMA channel power). The BBX2 then de-keys and, the applicable redundant BBX2 is assigned to the current TX antenna path under test. The test is then repeated. Upon completion of the test, OCNS is disabled on the specified MCC/CE.

All tests are performed using the external calibrated test set as the signal source controlled by the same command. All measurements will be via the LMF. The pilot gain is set to 262 for each TX antenna and all channel elements from the MCCs are forward-link disabled. The BBX2 is keyed up using only bbxlvl level offsets, to generate a CDMA carrier (with pilot channel element only). BBX2 power output is set to –20 dBm as measured at the TX OUT connector (on either the BTS or RFDS directional coupler). The BBX2 must be keyed in order to enable the RX receive circuitry. The LMF prompts the MCC/CE under test to measure all zero longcode and provide the FER report on the selected active MCC on the reverse link for both the main and diversity RX antenna paths, verifying the results meet the following specification: FER returned less than 1% and total frames measured is 1500. All MCC/CEs selected are tested on the specified RX antenna path. The BBX then de-keys and, the applicable redundant BBX2 is assigned to the current RX antenna paths under test. The test is then repeated.
