LMF Folder Structure
ti-cdma-05823.eps
The loads folder and all the folders below it are no longer contained on the LMF
CD as of LMF 2.9.0.0. When installing LMF software on a system that has never
contained LMF software before, the user will need to create these folders manually.
When installing a new version of LMF onto a PC already containing LMF software,
any existing folders will be unaffected.
WinLMF Directory
The CDMA LMF installation program creates the default home directory, c:\wlmf, and installs the
application ﬁles and subdirectories (folders) in it. Because this can be changed at installation,
the CDMA LMF home directory will be referred to with the generic convention of:
:\lmf home directory>
Where:
= the LMF computer drive letter where the CDMA LMF home directory is located.
= the directory path or name where the CDMA LMF is installed.

Preparing the LMF
WinLMF Operating System Installation
This section provides information and instructions for installing and updating the LMF software
and ﬁles.
First Time Installation Sequence:
1.
Install Java Runtime Environment (JRE)
2.
Install U/WIN K-shell emulator (optional)
3.
Install LMF application programs
Any time U/WIN is re-installed, the LMF application software must also be
re-installed. This is because the LMF application installation modiﬁes some of
the ﬁles that are installed during the U/Win installation. These modiﬁcations are
necessary for proper LMF CLI operation.
If required, a separate CD ROM of UBS Binaries may be obtained for binary updates.
First Time Installation Sequence
Follow the procedure in Procedure 3-1 to install the LMF application program using the LMF
CD ROM.
Procedure 3-1
CD ROM Installation
Insert the LMF Program CD ROM into the LMF CD ROM drive.
•
If the Setup screen appears, follow the instructions displayed on the
screen.
•
If the Setup screen is not displayed, proceed to step 2.
Click on the Start button.
Select Run.
Enter d:\autorun in the Open box and click OK.
If applicable, replace the letter d with the correct CD ROM drive
letter.

Basic WinLMF Operation
LMF Coverage in This Publication — All references to the LMF in this publication are for the
CDMA application program
Operating Environments — The LMF application program allows the user to work in the two
following operating environments which are accessed using the speciﬁed desktop icons:
•
Graphical User Interface (GUI) using the WinLMF with UBS Support icon
•
Command Line Interface (CLI) using the WinLMF CLI UBS icon
CLI can be run if the GUI is already running.
Basic Operation — 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. Both operations allow the following:
•
Selecting and deselecting UBS devices
•
Unlocking devices
•
Locking devices
•
Resetting devices
•
Obtaining device status
The following additional basic operation can be performed in a GUI environment:
•
Sorting a status report window
•
Displaying the Electronic Identiﬁcation (EID) information of the FRUs
For detailed information on performing these and other LMF operations, refer to the LMF
On-Line Help.
Unless otherwise noted, LMF procedures in this manual are performed using the
GUI environment.

Online Help - Task oriented online help is available in the LMF by clicking on Help from the
menu bar.
The LMF Display and the UBS
UBS Display - When the LMF is logged into a UBS, a frame tab is displayed. The frame tab will be
labeled with Frame, the UBS number, a dash, and the frame number (for example, Frame-812-1
for UBS 812, RFMF 1). There is only one frame for the UBS, so there will only be one tab.
Graphical User Interface Overview
The LMF uses a Graphical User Interface (GUI), which supports the following functions:
•
Selecting a device or devices
•
Selecting an action to apply to selected device(s)
•
Status report window displaying progress of actions taking place and related information
•
Notiﬁcation when an action is complete and related information such as indication of
success or failure
•
An OK button to close the status report window.
Understanding GUI Operation
For detailed information on GUI operation and the LMF, refer to the LMF Help function on-line
documentation.
Command Line Interface Overview
The LMF also provides Command Line Interface (CLI) capability. Activate the CLI by clicking on
a shortcut icon on the desktop. The CLI can only be launched while the GUI is running.
If the CLI tool was NOT installed, it is possible to telnet to the CLI without
the UWIN tool by using the command line in windows (RUN-> cmd) and typing

The process of downloading code to a UBS consists of two principal steps:
1.
Code transfer to the UBS followed by distribution to the devices
2.
Code activation
Normally, the OMC-R will download code to the UBS through the span line once the UBS is
conﬁgured to establish communication with the OMC-R. However, there may be some occasions
that the LMF may be used to download load instead, such as at a staging location used to
pre-load replacement DMIs with same code load version required by OMC-R. Then, when the
new DMI is taken to the site, it will integrate and synchronize much faster with the OMC-R.
When the code is activated, the UBS will re–start, and the LMF will lose contact with the UBS.
It will be necessary to log into the UBS again after the UBS devices complete initialization
with the new code.
Prerequisites
The following must be accomplished before downloading code:
•
A bts–# folder has been created for the UBS in the cdma subdirectory of the LMF home
directory. (Refer to WinLMF File Structure Overview on page 3-3)
•
The current NECB-—bts#.xml and NECJ-—bts#.xml ﬁles for the UBS are saved in the UBS bts–# folder
•
The LIF.xml ﬁle and code and data binary ﬁles for the software release are saved in the
cdma\loads\ subdirectory folder of the LMF home directory, where
is the number of the software release installed on the BSS. The
should be the same as deﬁned in the NECB/NECJ ﬁles
•
The LMF is logged into the UBS in invasive mode
If WinZip is used to unzip codeload, please be sure to uncheck the CR/LF conversion
on the WinZip tool: From WinZip window, select Options -> Conﬁguration ->
Miscellaneous and unchecked TAR ﬁle smart CR/LF conversion box.
Download Procedure
Code ﬁles are downloaded to the UBS using an FTP server. The user is given a choice of using
the built–in LMF FTP server or an external FTP server. For initial download of a UBS, the built–in
FTP server in the LMF should be used. This procedure covers using the LMF built–in FTP server.

Download Code to UBS
The UBS code load should always be synchronized with the download from the
OMC-R before leaving the UBS site. Refer to Reset All Devices and Initialize Site
Remotely on page 5-8 for the procedure to do this.
Procedure 3-5
Download Code
In the menu bar of the Local Terminal BTS window, select BTS > Download Code...
If prompted that the “Following operation may overwrite NECB, NECJ, LIF, and calibration
ﬁles on the BTS”, click Yes.
In the dialog box which appears, if the Use Local FTP server checkbox is not checked, click
in it to select this option.
Result: A check mark will appear in the box.
In ﬁeld labeled Software version enter the as speciﬁed in the
prerequisite section (for example, 2.19.0.0.20).
If a “clean download” is required (download every ﬁle, even if they are the same as those
currently installed on the UBS), click in the Perform clean load checkbox.
Result: A check mark will appear in the box.
Click Ok to start the download.
Code download can require up to 40 minutes to complete.
When the download is complete, click Ok to close the status report window.
When the code load is complete, the UBS will re–start, and the LMF will lose
contact with the UBS.
Log the LMF into the UBS again.

Connecting Test Equipment to the UBS
The following equipment is required to perform optimization:
•
LMF
•
Communications system analyzer model supported by the LMF
•
Non-radiating transmit line termination load
•
Directional coupler and in-line attenuator
•
RF cables and connectors
•
Null modem cable (see Figure 1-1)
•
GPIB interface box
The following ﬁgures provide representative illustrations of connections for test equipment
currently supported by the LMF:
•
Figure 3-23, Figure 3-24, Figure 3-25, and Figure 3-26 show the test set connections
for TX calibration.
•
Figure 3-27, Figure 3-28, Figure 3-29, and Figure 3-30 show test set connections for
optimization/ATP tests.
•
Figure 3-31, Figure 3-32, Figure 3-33, or Figure 3-34 illustrate cable calibration test set–up.
Test Equipment GPIB Address Settings
All test equipment except the Agilent E7495A and Anritsu MT8212B is controlled by the LMF
through an IEEE-488/GPIB bus. To communicate on the bus, each piece of test equipment must
have a GPIB address set which the LMF will recognize. The standard address settings used by
the LMF for the various types of test equipment items are as follows:
•
Signal generator address: 1
•
Power meter address: 13
•
Communications system analyzer: 18
Using the procedures included in the Setting GPIB Addresses section of Appendix D Test
Equipment Preparation, verify and, if necessary, change the GPIB address of each piece of test
equipment used to match the above.

Supported Test Equipment
Optimization and ATP testing for CDMA2000 1X sites or carriers may be performed using the
following test equipment:
•
Advantest R3267 Analyzer with Advantest R3562 Signal Generator
•
Agilent E4406A with E4432B Signal Generator
•
Agilent 8935 series E6380A communications test set (formerly HP 8935) with option 200
or R2K and with E4432B signal generator for 1X FER
•
Agilent E7495A or Agilent E7495B communications test sets
The E4406A/E4432B pair, or the R3267/R3562 pair, should be connected together using a GPIB
cable. In addition, the R3562 and R3267 should be connected with a serial cable from the Serial
I/O to the Serial I/O. This test equipment is capable of performing tests in both IS-95 A/B mode
and CDMA 2000 mode if the required options are installed.
To prevent damage to the test equipment, all TX test connections must be through the
directional coupler and in-line attenuator as shown in the test setup illustrations.
Optional test equipment
A spectrum analyzer, such as the HP8594E, and a signal generator supporting the required
frequency ranges can be used to perform manual cable calibration.

Test Equipment Preparation
See Appendix D Test Equipment Preparation for speciﬁc steps to prepare each type of test
set and power meter to perform calibration and ATP. The Agilent E7495A communications
test set requires additional setup and preparation. This is described in detail in Appendix D
Test Equipment Preparation.
Calibration of the communications test set (or equivalent test equipment) must be
performed at the site before calibrating the overall test equipment set. Calibrate the
communications test set after it has been allowed to warm up and stabilize for a
minimum of 60 minutes.
If any piece of the test equipment set (for example, test cable, RF adapter) has
been replaced, the test equipment set must be re–calibrated. Failure to do so could
introduce measurement errors, resulting in incorrect measurements and degradation
to system performance.
Equipment Warm-up
Warm-up UBS equipment for a minimum of 60 minutes prior to performing the UBS optimization
procedure. This assures UBS site stability and contributes to optimization accuracy.
Time spent running initial power-up, hardware/ﬁrmware audit, and UBS download
counts as warm-up time.
Before connecting any test equipment directly to any UBS TX or duplexed TX/RX
connector (for example, the TX/RX M connectors for a UBS equipped with IDRFs),
verify there are NO channels keyed. At active sites, have the OMC–R place the carriers
assigned to the XMI under test OOS. Failure to do so can result in serious personal
injury and/or equipment damage.

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 - 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.

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.

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.

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. Each subsection includes a procedure for manually
specifying test equipment items and a procedure to have the LMF automatically detect the
connected test equipment.

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.
(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.

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.

Setting Cable Loss Values
Cable loss values for the TX and RX test cable conﬁgurations are normally set by accomplishing
cable calibration using the applicable test equipment. The resulting values are stored in the
cable loss ﬁles. The cable loss values can also be set/changed manually.
If cable calibration was performed without using the LMF, cable loss values must be
manually entered in the LMF database. Failure to do this will result in inaccurate UBS
calibration and reduced site performance.

Introduction
General
The Acceptance Test Procedures (ATP) 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 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.

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.

Should the UBS Macro be equipped with EV-DO cards/modules, refer to 1x EV-DO System

Receive Signal Strength Indication Acceptance Test
Overview This test veriﬁes Receive Signal Strength Indication (RSSI) 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. 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.

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.

TX and RX Testing
The following individual ATP tests can be used to evaluate speciﬁc aspects of UBS operation
against individual performance requirements. All testing is performed using the LMF GUI
environment.
TX Testing
TX tests verify transmit antenna paths and output power control. All tests are performed using
the external, calibrated test equipment. All measurements are made at the appropriate UBS
TX OUT connector(s).
TX tests verify TX operation of the entire CDMA forward link using selected sector-carriers
assigned to respective sector antennas. Each sector-carrier is keyed up to generate a CDMA
carrier (using BLO) at the NEC ﬁle-speciﬁed carrier output power level.
RX Testing
RX testing veriﬁes receive antenna paths for the sector-carriers selected for the test. All tests
are performed using the external, calibrated test equipment to inject a CDMA RF carrier with
all zero long code at the speciﬁed RX frequency at the appropriate UBS RX IN connector(s).
RX tests verify RX operation of the entire CDMA reverse link.
Individual Tests
Standard Pattern (per the 3GPP2 standard) - For UBS Macro, the standard pattern is
the total digital gain of the signal (383) that includes the following channels (9 in all) and
their individual digital gain:
•
Pilot -171
•
Page - 165
•
Sync - 83
•
6xTCH - 117
In the UBS Macro, the pilot is set to 36dBm, which brings the total power of this pattern to
43dBm - 7dB higher.
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 NEC ﬁle values.

1X UBS Macro BTS Optimization/ATP
Individual Tests
Waveform Quality (Rho)
This test veriﬁes the transmitted Pilot channel element digital waveform quality of each
sector-carrier enabled at a speciﬁc frequency per the current NEC 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 connector.
Pilot Time Offset
The Pilot Time Offset is the difference between the CDMA analyzer measurement interval (based
on the UBS system time reference) and the incoming block of transmitted data from the UBS.
Code Domain Power/Noise Floor
This test veriﬁes the Code Domain Power/Noise of each sector-carrier is enabled at a speciﬁc
frequency per the current NEC 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 connector.
Frame Error Rate (FER)
The Frame Error Rate (FER) test veriﬁes RX operation of the entire CDMA Reverse Link
using all equipped DMIs assigned to all respective sectors/antennas. This test veriﬁes the
UBS sensitivity on all trafﬁc channel elements currently conﬁgured on all equipped DMIs at
an RF input level of -123.0 dBm.
TX Audit
The TX Audit is a power out test that will pass within +/-2dB of the expected power. The
standard power per S-C is 43dBm and the Audit test will pass, if the output power is within the
limits listed above.
Calibration
It is optional, but supported. The calibration in UBS is always a negative number representing
the LOSS between the output of the XMI to the top of the frame. In this frame, it is typically
-1dB to –2dB depending on RF elements in the frame.
