Automated Acceptance Test Procedures – All–inclusive TX & RX Mar 2001 4-1 SCt4812T CDMA BTS Optimization/ATP DRAFT Introduction The Automated Acceptance Test Procedure (ATP) allows Cellular Field Engineers (CFEs) to run automated acceptance tests on all equipped BTS subsystem devices using the Local Maintenance Facility (LMF) and supported test equipment per the current Cell Site Data File (CDF) assignment. The results of these tests (at the option of the operator) are written to a file that can be printed. All tests are controlled from 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, R15.X (68P09251A59). Before performing any tests, use an editor to view the “CAVEATS” section of the “readme.txt” file in the c:\wlmf folder for any applicable information. The ATP test is to be performed on out-of-service (OOS) sectors only. DO NOT substitute test equipment not supported by the LMF. IMPORTANT * Refer to Chapter 3 for detailed information on test set connections for calibrating equipment, cables and other test set components, if required. NOTE Customer requirements determine which ATP tests to are to be performed, and the craftsperson 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 GLI, MCC, BBX, and CIO cards, the LPAs and passive components including splitters, combiners, bandpass filters, and RF cables.
All RX: RX tests verify the performance of the BTS receiver line up. These include the MPC (for starter frames), EMPC (for expansion frames), CIO, BBX, MCC, and GLI cards and the passive components including RX filters (starter frame only), and RF cables. . . . continued on next page 4 Automated Acceptance Test Procedure – All–inclusive TX & RX – continued DRAFT SCt4812T CDMA BTS Optimization/ATP Mar 2001 4-2
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. ATP Test Prerequisites Before attempting to run any ATP tests, ensure the following have been completed:
BTS has been optimized and calibrated (see Chapter 3).
LMF is logged into the BTS.
CSMs, GLIs, BBXs, MCCs, and TSU (if the RFDS is installed) have correct code load and data load.
Primary CSM, GLI, and MCCs are INS_ACT.
BBXs are calibrated and BLOs are downloaded.
BBXs are OOS_RAM.
Test cables are calibrated.
Test equipment is connected for ATP tests (see Figure 3-13 through Figure 3-16 starting on page 3-50).
Test equipment has been warmed up 60 minutes and calibrated.
GPIB is on. Before performing the FER, 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. WARNING TX OUT Connection Many of the acceptance test procedures require taking measurements at the TX OUT (BTS/RFDS) connector. At sites without RFDS installed, all measurements will be via the BTS TX OUT connector. At sites with RFDS installed, all measurements will be via the RFDS directional coupler TX OUT connector. IMPORTANT * 4 Automated Acceptance Test Procedure – All–inclusive TX & RX – continued Mar 2001 4-3 SCt4812T CDMA BTS Optimization/ATP DRAFT 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.

This includes verifying module placement, jumper, and dual in–line package (DIP) switch settings against the site-specific documentation supplied for each BTS application. Next, pre-power up and initial power-up procedures are presented. Cell Site Types Sites are configured as Omni with a maximum of 4 carriers, 3–sectored with a maximum of 4 carriers, and 6–sectored with a maximum of 2 carriers. Each type has unique characteristics and must be optimized accordingly. For more information on the differences in site types, please refer to the BTS/Modem Frame Hardware Installation manual. CDF The Cell-site Data File (CDF) contains site type and equipage data information and passes it directly to the LMF during optimization. The number of modem frames, C–CCP shelves, BBX boards, MCC boards (per cage), and linear power amplifier assignments are some of the equipage data included in the CDF. Be sure that the correct bts–#.cdf and cbsc–#.cdf files are 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 cause system errors. Failure to use the correct CDF files to log into a live (traffic carrying) site can shut down the site. IMPORTANT * Site Equipage Verification Review the site documentation. Match the site engineering equipage data to the actual boards and modules shipped to the site. Physically inspect and verify the equipment provided for the BTS or Modem frame and ancillary equipment frame. Always wear a conductive, high impedance wrist strap while handling any circuit card/module to prevent damage by ESD. After removal, the card/module should be placed on a conductive surface or back into the anti–static shipping bag. CAUTION Initial Installation of Boards/Modules Follow the procedure in Table 2-1 to verify the initial installation of boards/modules. . . . continued on next page 2 Preliminary Operations: Overview – continued DRAFT SCt4812T CDMA BTS Optimization/ATP Mar 2001 2-2 Table 2-1: Initial Installation of Boards/Modules StepAction 1Refer to the site documentation and install all boards and modules into the appropriate shelves as required. Verify they are NOT SEATED at this time. NOTE On 800 MHz systems, the Switch Card has a configuration switch that must match the site configuration (see Figure 2-1). 2As the actual site hardware is installed, record the serial number of each module on a “Serial Number Checklist” in the site logbook.

FCC Filing- SC4812T @ 800 MHz CDMA BTS 1 DESCRIPTIVE INFORMATION FCC FILING FOR SC4812T @800 MHz CDMA BTS The Information in this exhibit is in accordance with the FCC Rules and Regulations, Vol. II, Part 2, Subpart J. Sections 2.1033 through 2.1055 are addressed. Section 2.1033 (a) Name of Applicant and Manufacturer: MOTOROLA Section 2. 1033 (b) Identification of Equipment: IHET5BL1 Section 2. 1033 (c) Quantity Production: Quantity Production is planned. Section 2. 1033 (d) Technical Description This Transmitter is intended for use in the Public Cellular Radio Telecommunications Service and is designed in compliance with the FCC Rules and Regulations Title 47, Part 22(H). This transmitter is capable of spread spectrum (CDMA) operation, and allows up to 128 Walsh codes to support Pilot, Sync, Paging, Supplemental, and Traffic channels. (1) Types of Emissions This equipment will be capable of operation using wide band spread spectrum techniques employing Direct Sequence Code Division Multiple Access (DS-CDMA) digital communication techniques. For this transmitter, the emission designator is 1M25F9W (per FCC Part 2.201, subpart C). (2) Frequency Range This transmitter operates within the 869.70 to 893.31 MHz Band (per FCC Part 22). This base station will support CDMA operations on channel numbers 1013 through 1023 and 1 through 777 inclusive. (3) Range of Operating Power The rated maximum average power out of the SC4812T @800 MHz CDMA BTS is 40 W (46.0 dBm) per RF carrier. However, in CDMA the actual power output is based on the number of traffic channels in operation. The minimum power occurs when only a pilot signal is present. The maximum power occurs when a pilot along with synchronization, paging, and traffic channels are present. For a typical system setup, the theoretical difference between minimum power and maximum power is about 20 dB. The output power is variable in 0.25 dB steps. FCC Filing- SC4812T @ 800 MHz CDMA BTS 2 (3) Range of Operating Power (cont.) In addition, the dynamics of a CDMA system allow for what is called “cell breathing”. This allows an operator to vary the range of a cell by controlling the power of the pilot signal. (4) Maximum Power Limits The peak output power of a base station transmitter may not exceed 100 Watts as defined in Part 22.913(a). (5) Applied voltages and currents into the final transistor elements of the transmitter output: In the CDMA system, the applied voltages and currents into the final transistor elements SRF7042X4 for 40 W output: Drain 27.7 VDC Drain Current 1.0 AMPS x 3 Gate Voltage 4 VDC (6) Function of Each Active Device Refer to the Operational Description Exhibit. (7) Complete Circuit Diagrams Refer to the Schematics Exhibit. (8) Instruction/Installation Manual Refer to the Installation Manual Exhibit. (9) Tune-Up/Optimization Procedure Refer to the Users Manual Exhibit. FCC Filing- SC4812T @ 800 MHz CDMA BTS 3 (10) Means for Frequency Stabilization Refer to Section F of the Test Report Exhibit. The Clock Synchronization Module (CSM/CSM2) provides clock and time signals for an SC4812T @800 MHz CDMA BTS. In addition, it provides the primary source, a 3 MHz clock, for the transmit synthesizer in the Broadband Transceiver. The CSM/CSM2 relies on a GPS receiver, either riding piggyback onto the CSM/CSM2 card or remotely located in an integrated package with the GPS antenna as the primary time reference for the ovenized oscillator. Two types of redundancy are provided: 1) Dual CSM/CSM2 cards provide redundancy in case of primary CSM/CSM2 failure. 2) Redundancy is also provided by either a High Stability Oscillator (HSO) or a Low Frequency Reference (LFR), such as a Loran C receiver, residing in a separate slot. The HSO is provided in case of GPS system failure. The CSM/CSM2 uses the received signals as a reference to provide the required clock for the site. The CSM/CSM2 distributes CDMA time, a 19.6608 MHz clock, and a two second synchronization pulse every even second of universal time to the CDMA Clock Distribution (CCD) Cards . The CSM/CSM2 is also responsible for configuration and management of the GPS and LFR systems. CSM/CSM2 software determines on a site basis what the GPS and LFR configurations should be. For future Commercial CDMA systems, GPS and LFR configuration information could optionally be downloaded to the CSM/CSM2 from the GLI2. The CSM/CSM2 is managed by the GLI2. The High Stability Oscillator (HSO) or Low Frequency Time Reference (LFR) is used to provide a stable time reference in case of a GPS system failure or shutdown. The output of the LFR card is routed to the CSM/CSM2 cards, which derive the appropriate time references for the RF section. The current LFR is a LoranC receiver. In areas where LoranC is unavailable, the HSO may be used. FCC Filing- SC4812T @ 800 MHz CDMA BTS 4 (11) Means for Attenuation of Spurious Emissions Refer to Section C of the Test Report Exhibit. Band pass filters are employed in the transmit RF circuit to attenuate far out spurious emissions. The filter used here is of an air dielectric cavity resonator type. In addition to the digital filters described below, the baseband also employs a discrete anti-alias filter that attenuates signals greater than 2MHz. Out of band emissions are also attenuated by ceramic filters in the transmit RF lineup. In addition, suppression of spurious radiation is obtained by proper shielding techniques. Means for Limiting Modulation Refer to Sections B and F of the Test Report Exhibit. In a CDMA system, the input signal (voice for example) is sampled and coded in a vocoder. This signal is then spread to 1.23 MHz by a pseudo-random spreading code. This spreading code sets the bandwidth of the spread-spectrum signal. If more than one signal is in operation (i.e. more than one voice channel), then the two signals are simply layered one atop the other within the 1.23 MHz band. So, to some extent, the bandwidth of the transmitted signal is limited by the chip rat…
