Additional information on each interface type is provided in the following subsections. COM Port Interface The LMF computer RS-232 serial bus interfaces are designated as COM connections or ports in software. These interfaces support communication with test equipment connected to the LMF computer either directly with a serial cable or through a GPIB interface device (GPIB box). The LMF normally uses COM1 for the interface. COM2 is not used unless the LMF computer has two RS-232 connectors. The COM port selected in the LMF can not be used for any other purpose when the LMF is using it. Selecting the COM port - Perform the following to select a COM port for use with test equipment needing either a GPIB or a direct serial connection: Procedure 3-6 Selecting a COM Port for GPIB or Serial Test Equipment Connection From the LMF window menu bar select Tools > Options. Result: The LMF Options window opens. If the Test Equipment tab is not in the forefront, click the tab to bring it forward. Click in the COM radio button in the GPIB/COM settings area. Result: A black dot appears in the circle. Select the COM port to use (normally COM1) from the dropdown in the Port: box of the GPIB/COM settings area. Click the Save button to save the selection configuration for future LMF sessions. Click the Close button to close the LMF Options window. 68P09283A63-5 3-45 FOA AUG 2007 Test Equipment Connection to the LMF Chapter 3: LMF Operation Disconnecting and Reconnecting the LMF and the COM port - The LMF can be disconnected from the active COM port by using the Disconnect Port button in the GPIB/COM settings area of the Test Equipment tab. Disconnecting the LMF may be needed, for example, to use a HyperTerminal connection for a hardware Man Machine Interface (MMI) communication session. Perform the following to disconnect or reconnect the LMF and the selected COM port. Procedure 3-7 Disconnect and Reconnect the LMF and the Active COM Port From the LMF window menu bar select Tools > Options. Result: The LMF Options window opens. If the Test Equipment tab is not in the forefront, click the tab to bring it forward. Disconnect the LMF from the active COM port: click the Disconnect Port button in the GPIB/COM settings area. Reconnect the LMF to the active COM port: click the Detect button in the GPIB Test equipment or Serial Test Equipment area. If no other operations are required in the LMF Options window click Close to close the window. Ethernet Interface The LMF computer Ethernet interface supports communication with test equipment which uses the network connection method. This interface uses Internet Protocol (IP) addressing to differentiate each node on the network. Motorola recommends that the Ethernet connection be done through an Ethernet hub. The hub connects to the LMF computer, the test equipment, and the base station Local Area Network (LAN). Connection details are as follows: Test equipment to hub – This is an Unshielded Twisted Pair (UTP) Ethernet cable with two 10/100Base–TX 8-contact modular connectors. LMF to hub – Use one of the following cable types to connect the LMF to the Hub: • Ethernet cable. Be sure the computer Network Interface Card (NIC) is set for either AUTO or to use the 8–contact modular connector only. • Coaxial cable between NIC and Hub. For a computer NIC equipped with a 10Base–2 (BNC) connector, use a BNC tee connector on the hub. If the hub does not have BNC connectors, use a BNC–to–UTP adapter with the tee connector. Connect a coaxial cable between the NIC and one end of the BNC tee crossbar. Hub to base station– Use one of the following, depending on the type of base station to be calibrated or tested: • For UBS with 10/100Base–T LAN: Connect an Ethernet cable between the hub and the SSI CRMS/LMT CUSTOMER ENET connector. 3-46 68P09283A63-5 FOA AUG 2007 1X UBS Macro BTS Optimization/ATP Test Equipment Connection to the LMF Addressing Methods Different addressing methods are used for test equipment depending on the type of interface connection it has. The different addressing methods are described in the following subsections. 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 set in 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 sections of Appendix D Test Equipment Preparation. Serial Connection This connection type uses a direct serial connection between the test equipment and the LMF computer platform. The Anritsu MT8212B communications test set is an example of test equipment using this type of connection. There are no specific addressing requirements for this type of interface. IP Addresses Test equipment using the Network connection type use IP addresses to identify them on the Ethernet LAN. The E7495A and E7495B communications test sets are examples of Network connection test equipment. Setting the IP address in the test equipment is covered in the specific test equipment (for example, Agilent E7495) set-up section of Appendix D Test Equipment Preparation. 68P09283A63-5 3-47 FOA AUG 2007 Test Equipment Selection Chapter 3: LMF Operation Test Equipment Selection ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Test Equipment Selection Test equipment selection is performed in the LMF Options window, accessed through Tools > Options in the LMF window menu bar. The window has four tabs covering different categories of options. Test equipment operations, including selection, are performed on the Test Equipment tab. For software release 2.20.0.x (R20), the test equipment list displayed on this tab is context sensitive based on the Connection type selected. • When GPIB is selected, only test equipment with a GPIB interface is displayed. • When Serial is selected, only test equipment needing a direct serial connection is displayed. • When Network is selected, only test equipment needing an Ethernet connection is displayed. Manual and Autodetect Selection Test equipment can be manually specified before or after the test equipment is connected. The LMF does not try to determine if the test equipment is actually connected for manual selection. The LMF can be commanded to automatically detect test equipment connected to it. This autodetection feature is operated by a Detect button located in the test equipment list area for each connection type (GPIB, Serial, or Network). Selecting Test Equipment There is a different set of test equipment selection procedures for each test equipment connection type. These are: • GPIB connection • Serial connection • Network (Ethernet) connection Selection Procedures Test equipment selection procedures are contained in the following subsections. Each subsection is for a different connection type.

If the test equipment set being used to interface with the base station has been calibrated and maintained as a set, this procedure does not need to be performed. (Test equipment set includes LMF computer, communications test set, additional test equipment, associated test cables, and adapters.) This procedure must be performed before beginning the optimization. Verify all test equipment (including all associated test cables and adapters actually used to interface all test equipment and the base station) has been calibrated and maintained as a set. 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. 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. 68P09283A63-5 3-55 FOA AUG 2007 Test Set Calibration Chapter 3: LMF Operation Calibration Procedures Included Automatic Procedures included in this section use the LMF automated calibration routines to determine path losses of the supported communications analyzer, 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 test measurement offset file on the LMF computer. Manual Agilent E4406A Transmitter Tester - The E4406A does not support the power level zeroing calibration performed by the LMF. If this instrument is to be used for Bay Level Offset calibration and calibration is attempted with the LMF Calibrate Test Equipment function, the LMF will return a status window failure message stating that zeroing power is not supported by the E4406A. Refer to Appendix D Test Equipment Preparation for instructions on using the instrument’s self-alignment (calibration) function prior to performing Bay Level Offset calibration. Power Meters - Manual power meter calibration procedures to be performed prior to automated calibration are included in Appendix D Test Equipment Preparation. Cable Calibration - Manual cable calibration procedures using the Advantest R3465 communications system analyzer are provided in Appendix D Test Equipment Preparation, if needed. Prerequisites Ensure the following prerequisites have been met before proceeding: • Test equipment is correctly connected and turned on. • Test equipment addressing is set as required for the connection type being used (GPIB, Serial, Network) Calibrate Test Equipment Function (Except Agilent E4406A and Anritsu MT8212B) The Calibrate Test Equipment function zeros the power measurement level of the test equipment item to be used for TX calibration and audit. If both a power meter and an analyzer are connected, only the power meter is zeroed. 3-56 68P09283A63-5 FOA AUG 2007 1X UBS Macro BTS Optimization/ATP Test Set Calibration 1.

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: • Measuring the loss of a short cable – This is required to compensate for any measurement error of the analyzer. The short cable (used only for the calibration process) is used in series with both the TX and RX cable configuration when measuring. 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. The result is then adjusted out of both the TX and RX measurements to compensate for the measured loss. • Measuring the short cable plus the RX cable configuration loss – 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 of the test equipment. Refer to Figure 3-31, Figure 3-32, Figure 3-33, or Figure 3-34 for specific cable and connection requirements for each type of communications system analyzer. • Measuring the short cable plus the TX cable configuration loss – The TX cable configuration normally consists of two coax cables with type N connectors and a directional coupler, a load, and an additional attenuator (if required by the specified BTS). The total loss of the path loss of the TX cable configuration must be as required for the BTS (normally 30 or 50 dB). Refer to Figure 3-31, Figure 3-32, Figure 3-33, or Figure 3-34 for specific cable and connection requirements for each type of communications system analyzer. Cable Calibration Set–up Diagrams Figure 3-31 and Figure 3-32 show the cable calibration set–up for various supported test sets. The left side of the diagram depicts the location of the input and output connectors of each test equipment item, and the right side details the set up for each test. Calibrate Test Cabling using Communications System Analyzer Cable Calibration is used to calibrate both TX and RX test cables. 3-64 68P09283A63-5 FOA AUG 2007 1X UBS Macro BTS Optimization/ATP Cable Calibration Prerequisites Ensure the following prerequisites have been met before proceeding: • One of the following: LMF computer serial port and test equipment are connected to the GPIB box For MT8212B, the test equipment is connected to the LMF computer serial port For E7495A/B, the LMF computer NIC and the E7495 are connected to the Ethernet hub (Test Equipment Connection section) • Test equipment is turned on and has warmed up for at least 60 minutes. • Test equipment has been selected/detected in the LMF (Refer to the Selection Procedures subsection of the Test Equipment Selection section) Calibrating cables Refer to Figure 3-31, Figure 3-32, Figure 3-33, or Figure 3-34 and perform the following to calibrate the test cable configurations.

LMF User Interface This chapter provides procedures for performing acceptance testing from the LMF Graphical User Interface (GUI) environment, the recommended method. The GUI provides the advantages of simplifying the LMF user interface, reducing the potential for mis-keying commands and associated parameters, and speeding up the execution of complex operations involving multiple command strings. If it is believed the LMF command line interface (CLI) will provide additional insight into ATP operation or unexpected test results, refer to LMF CLI Reference. Test Reports The CFE can choose to save the results of ATP tests to a report file from which ATP reports are generated for later printing. See the Generating an ATP Report section in this chapter. Test Equipment Selection Because test equipment functions during acceptance testing are controlled by the LMF directly, only the test equipment models supported by the LMF can be used. 1. Before using the LMF, read the Developer Release Notes for WinLMF section in the LMF Help function on-line documentation for any applicable information. Pay particular attention to the Caveats/Known Issues part of this appendix. 2. The ATP test is to be performed on out-of-service sectors only. 3. DO NOT substitute test equipment with other models not supported by the LMF. 4-2 68P09283A63-5 FOA AUG 2007 1X UBS Macro BTS Optimization/ATP Introduction to ATP Test Equipment Set Calibration Refer to Test Set Calibration on page 3-55,Cable Calibration on page 3-64, and Appendix D Test Equipment Preparation for detailed interconnection information needed for calibrating equipment, cables, and other test equipment set components. Equipment has been factory-tested for FCC compliance. If license-governing bodies require documentation supporting UBS site compliance with regulations, a full ATP may be necessary. Perform the Reduced ATP only if reports for the specific UBS site are NOT required. After verifying that the proper operational software was code synced to the UBS, the CFE must perform these procedures (minimal recommendation): 1. Verify the TX/RX paths by performing TX Audit and Receive Signal Strength Indicator (RSSI) tests. 2. Be sure calibration data for all equipped sector-carriers is obtained and loaded on the OMC-R 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 FRU Optimization and ATP Test Matrix in Appendix B FRU Optimization/ATP Matrix to determine the applicable test that must be performed. In the unlikely event that the UBS 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. 1x EV-DO ATP Should the UBS Macro be equipped with EV-DO cards/modules, refer to 1x EV-DO System ATP — 68P09283A59 for testing procedures. 68P09283A63-5 4-3 FOA AUG 2007 Acceptance Test Procedures - TX & RX Chapter 4: Acceptance Test Procedures Acceptance Test Procedures - TX & RX ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Reduced and Full ATP The full ATP (all the ATP tests) is optional.

Testing is performed using the calibrated external test equipment as the signal source. The test equipment is controlled by the LMF during the test. The receive signal generated by the test equipment is injected into the sector RX path to be tested at the applicable UBS main and / or diversity receive ports. Equipment Operation During Testing The LMF sets the pilot channel power level of the sector for the selected sector to +XX dBm (measured at the TX port of the frame) and enables the sector-carrier on pilot channel only to enable the RX circuitry. The LMF then commands the test equipment to generate the receive signal on the selected carrier at -80 dBm as measured at the UBS RX port Test Measurements The power level of the received signal is measured by the RFX. The LMF corrects the measured power of the signal using the RX BLO and determines if the corrected signal gain is equal to or greater than the following specified criteria for the band in which the UBS operates: • 1900 MHz: –80 dBm (-86 dBm or greater) • 800 MHz: –80 dBm (-86 dBm or greater) The LMF provides -80 dBm signal (default) input to the UBS. The RSSI must be +/-6 dB. Receive Signal Strength Indicator ATP Perform the following procedure for RSSI acceptance testing. Procedure 4-2 Procedure for RSSI Acceptance Testing Set up the test equipment for RX acceptance tests. Reference Figure 3-23 through Figure 3-26. Select the carrier to be tested.

Automated ATP This section covers the general requirements and procedures for conducting both automated ATP testing and performing individual ATP tests. Automated ATP Test Options Acceptance tests can be run individually or as one of the following automated groups: • All TX: TX tests verify the performance of the UBS transmit line up. • All RX: RX tests verify the performance of the UBS receiver line up. • All TX/RX: Executes all the TX and RX tests. • Full Optimization: Executes the TX calibration, downloads the BLO, and executes the TX audit before running all of the TX and RX tests. The Full Optimization test can be run if TX path calibration is needed before the TX and RX acceptance tests are run. The STOP button can be used to stop the testing process. The LMF is optimized to perform the tests as quickly as possible when selecting the “perform all" menu options. It is recommended that the user select this option on a per sector/carrier option where possible to save time. 68P09283A63-5 4-7 FOA AUG 2007 Acceptance Test Procedures - TX & RX Chapter 4: Acceptance Test Procedures Required Test Equipment The following test equipment is required: • LMF • Power Meter • Communications System Analyzer • Before connecting any test equipment directly to any UBS TX OUT connector, verify that there are no CDMA channels keyed. • At active sites, have the OMC-R operator place the carrier assigned to the UBS under test OOS. Failure to do so can result in serious personal injury and/or equipment damage. Test equipment must be calibrated and the cables re-calibrated before using them to perform acceptance tests. ATP Test Prerequisites Before attempting to run any ATP tests, ensure the following have been completed: • LMF is logged into the UBS. • All FRUs on the LMF screen are INS (Green) • Test cables are calibrated • Test equipment is connected for ATP tests (refer to ATP Test Setup illustrations in the Test Equipment Set Up section of Appendix E Optimization and Calibration Procedures) • Test equipment has been selected in the LMF, warmed up 60 minutes and calibrated • All required Ethernet test equipment connections are made • UBS transmit connectors are terminated with either non-radiating loads or connected to the test equipment as specified in Figure 3-27 through Figure 3-30. 4-8 68P09283A63-5 FOA AUG 2007 1X UBS Macro BTS Optimization/ATP Acceptance Test Procedures - TX & RX Before a FER test is run, be sure that the following is done: All transmitter connectors are properly terminated.

Procedure 4-3 Setup Test Equipment — TX Output Verify/Control Tests If it has not already been done, interface the LMF computer to the UBS. If it has not already been done, refer to Procedure 3-3 to start a GUI LMF session and log into the UBS. If it has not already been done, refer to Figure 3-23, Figure 3-24, Figure 3-25, or Figure 3-26 as applicable, for the test equipment and antennas being used, to connect test equipment for acceptance testing. LMF-based measurements factor in TX cable loss between the UBS and the test equipment. Antenna Connectors All acceptance testing requires test equipment connections to the UBS antenna TX or RX connectors. Refer to the ATP Test Setup illustrations in the Test Equipment Set Up section of Appendix E Optimization and Calibration Procedures for specific connection requirements Recommended Tests The recommended tests are TX Audit and Receive Signal Strength Indicator (RSSI) to confirm the physical assembly of the frame and that all the cables TX, RX, Digital etc are correctly connected. The rest of the tests are supported, optional, or for troubleshooting purposes. TX/RX ATP Test Procedure Follow the procedure in Procedure 4-4 to perform the All TX/RX ATP test.
