Test Equipment Connection to the LMF■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
■
■
Test Equipment Connection
The LMF computer platform provides two types of hardware interfaces which support three
different test equipment communication methods.
•The COM hardware interface (RS -232) supports connection with both of the following
communication methods:
General Purpose Interface Bus (GPIB)
Direct serial connection
•The Ethernet interface supports the network test equipment communication method.
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 - P erform 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 P ort for GPIB or Serial T est Equipment Connection

Disconnect
the LMF from the active COM port: click the Disconnect Port button in
the GPIB/COM settings area.
4
Reconnect
the LMF to the active COM port: click the Detect button in the GPIB T est
equipment or Serial T est Equipment area.
5
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:
T est equipment to hub – This is an Unshielded T wisted P air (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. F or 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:
•F or UBS with 10/100Base–T LAN : Connect an Ethernet cable between the hub and the S SI
CRMS/LMT CUSTOMER ENET connector .

1X UBS Macro B T S Optimization/A TP T est 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 1for a CDMA signal
generator , 13 for a power meter , and 18 for a communications system analyzer . T o verify
and, if necessary , change the GPIB addresses of the test equipment, refer to the
Setting GPIB
Addresses
sections of Appendix D T est 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
T est 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 T est
Equipment Preparation .

Test Set Calibration Background
Proper test equipment calibration ensures that the test equipment and associated test cables do
not introduce measurement errors, and that measurements are correct.
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.
(T est 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. V erify 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 an y piece of test equipment, test cable, or RF adapter , that mak es up the calibr ated
test equipment set, has been replaced, re -calibr ation must be performed. F ailure to
do so can introduce measurement errors, resulting in incorrect measurements and
degr adation 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
.

Calibrating Cables Overview
The cable calibration function measures 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:
•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.

Introduction
General
The Acceptance T est Procedures (A TP) allow Cellular Field Engineers (CFEs) to run automated
acceptance tests on all UBS subsystem devices equipped in the NEC using the LMF and the
test equipment it supports.
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 A TP operation or unexpected test results, refer to LMF CLI Reference.
Test Reports
The CFE can choose to save the results of A TP tests to a report file from which A TP reports are
generated for later printing. See the Generating an A TP 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 Dev eloper R elease Notes for WinLMF section in
the LMF Help function on -line documentation for an y applicable information. P a y
particular attention to the Ca v eats/Known Issues part of this appendix.
2. The A TP test is to be performed on out -of -service sectors only .
3. DO NO T substitute test equipment with other models not supported b y the LMF .

1X UBS Macro B T S Optimization/A TP Introduction to A TP
Test Equipment Set Calibration
Refer to T est Set Calibration on page 3 - 55 ,Cable Calibration on page 3 - 64 , and Appendix D
T est 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 A TP
may be necessary . P erform the Reduced A TP only if reports for the specific UBS
site are NOT required.
A fter verifying that the proper operational software was code synced to the UBS , the CFE must
perform these procedures (minimal recommendation):
1. V erify the TX/RX paths by performing TX Audit and Receive Signal Strength Indicator
(RS SI) 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 A TP T est Matrix in Appendix B
FRU Optimization/A TP 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.

Acceptance T est Procedures - TX & RX Chapter 4: Acceptance T est Procedures
Receive Signal Strength Indication Acceptance Test
Overview This test verifies Receive Signal Strength Indication (RS SI) for the selected sectors
to ensure integrity of the reverse (RX) path, that path losses are within tolerances required for
correct receiver operation, and correct installation of the RX path. T esting 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 T esting 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
T est 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 RS SI must be
+/ -6 dB.
Receive Signal Strength Indicator ATP

Automated ATP
This section covers the general requirements and procedures for conducting both automated
A TP testing and performing individual A TP 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.
