Product Description
Test Software Overview
Test Software Overview
The Test Software is contained on two One-Time Programmable (OTP) PC cards. One
card is used for AMPS testing, the other for CDMA testing. Separate manuals are
included for AMPS and CDMA testing.
The Test Software is an Agilent Technologies Instrument BASIC (IBASIC) application
used to set up the Test Set for transmitter measurements on AMPS Base Station
equipment. The Test Software runs on the Test Set internal IBASIC controller to allow
you to perform the following tests:
• Full Site Test (FCC)
• Single Radio Test
• TX Power Adjustment Test
• Spectrum Analyzer Test
• RX Gain Test
• TX Gain Test
• TX –39 dBm Power Test
Using a PC modem or a telnet connection, the Test Software can control the Base Station
equipment by sending commands to the Mobile Switching Center (MSC). This provides
automated testing to reduce time spent at the site and to greatly improve the
repeatability of measurements.
As tests are run, the Test Software compares the measured results with user-defined
specification limits. These test results may be stored on a personal computer (PC)
(ordinarily a laptop PC).
In addition, the following tests are included as calibration and utilities functions.
• TX Antenna Port Cable Calibration
• TX Test Port Cable Calibration
• TX Test Port Coupling Measurements
• Insertion Loss Measurement
• Return Loss Measurement
Also in addition, the following two miscellaneous utilities are included:
• Define Frequency Plan
• Print FCC Title Page

Operating the BTS Laptop Utility Program
Operating the BTS Laptop Utility Program
The Test Software can control the cell site to perform tests in much less time than would
be required under manual control. In order to control the Base Station, you may use a
PC and modem to dial the MSC directly, or you may use a PC to establish a telnet
connection to the MSC. The BTS Laptop Utility program running on that PC allows the
Test Set to communicate with the MSC through the PC for automatic testing.
NOTE
The method of site control described in this section is optional, but is highly desirable
when possible. If you elect to use other means of controlling the site equipment, some
information about the Base Station is still required. Enter the appropriate information
in the Base Station Configuration Menu screen (see “Base Station Configuration” on
page 39), skip the rest of this chapter, and start testing (see Chapter 4, “Performing
Tests,” on page 59). See also “Testing without MSC Control” on page 126.
If you elect not to control the MSC using a PC, you may skip the rest of this chapter. Note
however, that the procedures in Chapter 4, “Performing Tests,” on page 59 use a PC for
site control.
The BTS Laptop Utility program is shipped with the Test Software on two separate
3.5-inch diskettes. You must install the BTS Laptop Utility program on the PC to
communicate with the MSC. The utility program also provides several other helpful
functions.
The BTS Laptop Utility program provides the following window functions:
• Switch Terminal – A window that: 1) works with the PC internal modem to dial into
the MSC, or with the PC and a telnet connection to the MSC, and 2) displays the
information sent to and from the MSC.
• Test Set Terminal – A window in which you may view commands sent by the Test
Set to the MSC.
• Other Data – A window from which to download frequency plans to the Test Set and
in which short-form test results are displayed.
• Test Set Screen Capture – A window in which to capture screen images and save
each as a bit mapped image. This is very helpful when using the Test Set spectrum
analyzer or when you wish to capture some other screen. Note that IBASIC program
operation must be paused first, by pressing the Pause/Continue key, to print any of
the TESTS screens used for automated testing.
For more information on the windows in the above list, see “BTS Laptop Utility Program

Operating the BTS Laptop Utility Program
• Select and set the following Serial 9 Port Configuration Menu fields as appropriate
for operation with the BTS Laptop Utility program.
— Baud Rate – Select the field and then select a value from the drop-down Choices:
list to match the Baud Rate setting in the BTS Laptop Utility program Preferences,
Comm Port Setup drop-down window. The default value is 9600. However, the Test
Software will operate more quickly at 19200, so it is recommended that you change
the value to 19200.
NOTE
IMPORTANT: If you select a baud rate greater than 19200, the PC must remain
connected to the Test Set or the Test Set will not operate properly, and might
appear to be locked up.
— Data Length – Select the field and select 8 from the drop-down Choices: list.
— Parity – Select the field and select None from the drop-down Choices: list.
— Stop Length – Select the field and select 1 from the drop-down Choices: list.
— Flow Control – The default is None. If it is not set to the default, select the field and
select None from the drop-down Choices: list.
NOTE
For optimum performance, use the following settings for Flow Control:
For baud rates ≤ 19200, Flow Control should be set to None.
For baud rates >19200, Flow Control should be set to Hardware.
Step 2. On the PC, determine and record the PC serial COM port designation (for example,
COM1) from the Windows Device Manager Ports (COM & LPT) selection.
Step 3. On the PC, invoke the BTS Laptop Utility program. The BTS Laptop Utility program
tool bar will appear on the PC display.
Step 4. Select SW, TS, OD, or TR (any one will do) from the BTS Laptop Utility program tool
bar.
Step 5. Select Preferences, then Comm Port Setup.
Step 7. On the Comm Port Setup drop-down menu, in the Test Set - Baud Rate list, select

Installation
Operating the BTS Laptop Utility Program
Configuring the PC to Communicate with the MSC
After installing the BTS Laptop Utility program, if you are using the utility program to
communicate with the MSC, you must configure the PC to do so. This may be done in
either of two ways: 1) by using modem to dial the MSC directly, or 2) by using a telnet
connection. The telnet connection may be either a dial-up Internet connection, or a direct
Internet connection. The dial-up Internet connection would use the PC modem; the
direct Internet connection would use a PC LAN (the most common of which is ethernet).
Modem Connection
If you elect to use a modem connection, configure the MSC connection as follows:
Step 1. On the PC, determine and record the PC modem port COM designation (for example,
COM2) from the Windows Device Manager Modem selection.
Step 2. On the PC, invoke the BTS Laptop Utility program. The BTS Laptop Utility program
tool bar will appear on the PC display.
Step 3. Select SW, TS, OD, or TR (any one will do) from the BTS Laptop Utility program tool
bar.
Step 4. Select Preferences, then Comm Port Setup.
Step 5. On the Comm Port Setup drop-down menu, in the Switch - Port list, select the PC
COM port assigned to the PC modem, as determined in Step 1.
If the modem port is already in use, the Test Software will display a message stating that
a device already has control of that port. The most common cause is a communication
program running in the PC background. Close the other program and reselect the
required COM port.
Step 6. On the Comm Port Setup drop-down menu, in the Switch - Baud Rate list, select the
data transfer rate at which the PC will communicate with the modem. Note that this is
not the rate at which the modem will communicate with the MSC. Most modems
negotiate at the start of the session with the modem on the other end of the line for the
best data transfer rate. A typical setting is 57600.
Telnet Connection
If you elect to use a telnet connection, configure the MSC connection as follows:
Step 1. On the PC, invoke the BTS Laptop Utility program. The BTS Laptop Utility program
tool bar will appear on the PC display.
Step 2. Select SW, TS, OD, or TR (any one will do) from the BTS Laptop Utility program tool
bar.
Step 3. Select Preferences, then Comm Port Setup.
Step 4. On the Comm Port Setup drop-down menu, in the Switch - Port list, select Telnet.
Step 5. On the Comm Port Setup drop-down menu, the Switch - Baud Rate list is not active
for a telnet connection. Make no selection.

dial-up modem connection or a telnet connection. These methods are described in the
following sections.
Connect the PC to the MSC via a phone line or LAN connection as shown in Figure 2-6
Testing a Direct-Dial Modem Connection
The PC modem must be connected to a phone line capable of connecting to the MSC. If no
phone line is available at the Base Station, a wireless phone with a properly configured
wireless-capable modem will suffice.
Test a modem connection as follows:
Step 1. From the BTS Laptop Utility program tool bar, select SW.
Step 2. In the Switch Terminal window, select Dial.
Step 3. In the drop-down Dial window, enter the MSC phone number, then select OK (see
Figure 2-7).
Step 4. When prompted in the Switch Terminal window by the MSC, enter the same
commands that you would use in your usual communication program to log in to the
ECP. Once logged into the ECP, enter the maintenance craft shell. When you have
finished, a command prompt will appear, which indicates that the MSC is waiting for the
next command.
If you intend to start testing the Base Station soon, leave the MSC connection enabled. If
some time will elapse before you start testing, log off from the MSC, and select the
Hangup/Disconnect (HU) button in the Switch Terminal window.

Determining the Test Set to Site Equipment Connections
Determining the Test Set to Site Equipment
Connections
At this point in the process, you must decide the Test Set port and the Base Station port
to be used in testing. At appropriate points in a test sequence, the Test Software will
display prompts directing you to make connections. For details on the required
connections, see Chapter 3, “Connections,” on page 55.
Which Test Set Port to Use – ANT IN or RF IN/OUT?
CAUTION
The Test Set ANT IN port is only used for very low signal levels ≤ 60 mW (17.78 dBm).
Therefore, to prevent damage to the Test Set, never connect this port directly to the Base
Station TX Antenna Port. This port is typically connected to the Base Station TX Test
Port.
The Test Set RF IN/OUT port is for signals of ≤75 watts continuous wave or ≤15 watts
CDMA. This is the only port on the Test Set that you should connect directly to the Base
Station TX Antenna Port. If power levels from the Base Station exceed the specification
of the port, use an appropriate signal attenuator.
Which Base Station Port to Use – TX Test or TX Antenna?
Testing may be performed while connected to either the Base Station Test Port or the
Base Station Antenna Port. Testing at the Antenna Port involves taking the Base
Station out of service. The choices are described in the following sections.
In-Service Testing Using the Base Station TX Test Port

Coupling Factor is the loss through the

Chapter 2
35
Installation
The Base Station TX Test Port signal is derived from the directional coupler that is
connected between the Linear Amplifier and the Base Station TX Antenna Port (see
Figure 2-8). This allows you to make measurements on an active Base Station without
disconnecting the transmit antenna and interrupting service. You must enter a value for
the coupling factor (loss) through the directional coupler to compensate power
measurements (see “Test Configuration” on page 38). Coupling factors are typically 40 to
70 dB, but might vary, depending on the Base Station design.
Installation
Determining the Test Set to Site Equipment Connections
If you are uncertain of the exact coupling factor, the Test Software contains a utility to
measure the coupling factor (see “TX Test Port Coupling Measurements” on page 88).
NOTE
If you are uncertain of the Specified Output Power for the transmitter at the Base
Station TX Antenna Port, the Test Software must measure the power to calculate the
coupling factor. This requires that you take the Base Station out of service to connect the
Test Set directly to the Base Station TX Antenna Port during the calibration routine.
One disadvantage to using the Base Station TX Test Port to make measurements is the
possibility that its coupler is malfunctioning and therefore will cause erroneous
measurements. If TX power measurements fail by a large amount, but you suspect the
actual transmitted power is correct, take the Base Station out of service and make
measurements directly at the Base Station TX Antenna Port to verify the failing
reading. If the Test Software is correctly configured, TX power measurements using the
Base Station TX Test Port and TX Antenna Port should not differ significantly.
Out-of-Service Testing Using the Base Station TX Antenna Port
Disconnecting a TX antenna feed line and connecting the Test Set to the Base Station TX
Antenna Port (see Figure 2-8) requires that you first take the Base Station out of service
(disable call processing and turn off all transmissions to that TX Antenna Port).
The Base Station may be taken out of service (and turned back on to make
measurements) in two ways:
1. Access the MSC using a PC and the BTS Laptop Utility program to control the Base
Station through its maintenance software.
2. Call the MSC and have switch personnel control the Base Station for you.
One benefit of testing directly at the Base Station TX Antenna Port is the confidence
that the measurement will reflect the true output power of the Base Station at the point
at which the antenna feed line connects to the Base Station. This verifies the operation
of the full transmission path inside the Base Station. It also provides an opportunity to
perform transmission line and antenna testing while the antenna is disconnected from
the Base Station.

Defining a Frequency Plan
Defining a Frequency Plan
When running the Full Cell Site Test mode (see “Full Site Test (FCC)” on page 65), you
must provide information to the Test Software on the radios in the site being tested. This
is done using frequency plans. Frequency plans are defined on a per site basis. There
must be one plan for each site to be tested.
Once a plan is defined, you may store it on an SRAM card for later use for modification.
The Test Software supports two methods for entering the information into a frequency
plan. The first method uses an editor that is part of the Test Software. In this method, all
plan entry is done on the Test Set front panel. The second method uses an external PC
with an editing program. In this method, the plan is defined and then downloaded to the
Test Set for storage.
Defining a Frequency Plan Using the Editor in the Test Software
The process of defining a frequency plan using the editor function of the Test Software
requires saving the frequency plan on an SRAM card. Before beginning the plan
definition, make certain that an initialized SRAM card is available for file storage.
Step 1. From the Lucent AMPS Test Main Menu, select the Calibration/Utilities field. The
Test Software will display the Calibration/Utilities Menu screen.
Step 2. Select the Define Frequency Plan field. The Test Software will display the Define
Frequency Plan screen (see Figure 2-13). Note that the display is divided into two parts.
The top of the screen is used to perform file functions, and the lower part is used to edit
the data. Scroll to the Cell Site field and enter the number of the site for which the
plan is to be defined. To do this, either turn the knob to the desired site number and
press the knob to select that number, or use the DATA ENTRY keys to enter a site
number and either press the Enter key or press the knob to select that number.

Step 3. Select the Edit field to activate the lower part of the screen for editing. The first line will
show a highlighted one (1). Note that the USER key assignments on the right side of the
screen also changed to allow you to insert or delete lines of frequency plan information.
Step 4. Press the k1 (Ins Above) key to add lines to the list (see Figure 2-14). Each line of the
plan corresponds to one radio in the site.
Figure 2-14
Adding Lines to the Frequency Plan
Step 5. Press the knob to highlight the seven entries for that line in the plan (see Figure 2-15).
You may then modify the entries for that line by moving the cursor to the left of each
entry, pressing the knob, and changing the value using the DATA ENTRY keys or the
knob. After changing an entry, press the knob again to move to the next entry.

Step 6. Use the Line field to select each line in the plan (which corresponds to individual radios
in the site), and then enter these values for each line:
• ID Number — the Radio ID number (0 to 199)
• Chan Number — the radio channel number (1 to 1023)
• VRAL/CSAC — the Voice RAdio Level (VRAL) for an AMPS radio, or the Control Setup
Attenuation Code (CSAC) for an AMPS Setup radio. Range is 0 to 7.
• Output Power — the power at the TX antenna output from the Antenna Interface
Frame.
• Ant Number — the antenna number for that radio (0 to 6) (see Table 2-1).
• Radio Type — 0=AMPS radio, 1=AMPS Setup radio.

Defining a Frequency Plan
Create the Frequency Plan File
You may use any text editor that allows you to save a file in an ASCII format to create a
frequency plan. The following procedure outlines the process for creating a text file to
download to the Test Set:
If necessary, refer to the documentation for the PC application software for details on
opening new files, entering data, and storing the file.
NOTE
Step 1. Start the text editor program on the PC.
Step 2. Open a new file to begin editing.
Step 3. The guidelines for creating a plan for one site are as follows:
• You may enter the data in one long string or in a tabular format.
• Separators between numbers (delimiters) may be spaces, commas, periods, tabs, or
another non-numeric character. Enter a carriage return (Line feed, Return/Enter, and
so forth) and at least one alpha character after the last number in the last line in the
plan to define the end point of the plan.
• You may use text anywhere in the file to keep track of the numbers in the file. When
downloading the file to the Test Set, all non-numeric text is ignored (with the
exception of the carriage return, and alpha character to indicate the end of the plan
during the transfer).
• The first number in the file should be the Cell Site Number.
• The next line must contain values that match the Define Frequency Plan screen
fields (Line, IC Number, Chan Number, VRAL/CSAC, Output Power, Ant Number (see
Table 2-1 on page 45), and Radio Type (0=AMPS, 1=AMPS Setup). See Figure 2-18
for an example of a frequency plan definition. Again, the text is optional and you may
use other text or none at all.
• Add additional lines for each additional radio, again making sure that data for each
field is entered.
• Increment the Line field by one for each additional line you use.
Installation
Figure 2-18
Example Frequency Plan on the PC
The Cell Site number must be the first numeric character.
Always include at least one alpha character on a separate
line after the last numeric character to indicate to the Test

commands that you would use in your usual communication program to log in to the
ECP. Once logged into the ECP, enter the maintenance craft shell. When you have
finished, a command prompt will appear, which indicates that the MSC is waiting for
the next command.
Establishing a Telnet Connection
The telnet connection uses the Internet to connect to the MSC. You may use either a
direct connection (using a LAN such as ethernet) or a dial-up connection (using the PC
modem).
Test a telnet connection as follows:
2. From the BTS Utility program tool bar, select SW.
3. In the Switch Terminal window, select Dial.
4. In the drop-down Dial window, enter the IP address as the phone number, then select
OK (see Figure 2-7 on page 33).

NOTE
Testing might be interrupted if cell site diagnostics are initiated by the MSC while tests
are being run. To prevent this, use a personal computer (PC) (usually a laptop PC) to
send a command to inhibit diagnostics from the MSC before testing.
These test procedures describe the process from setting up a test to obtaining test
results. To simplify the procedures, all are written to use a PC to communicate with the
MSC (where applicable) and the Test Software will be set to send control commands.
Before making measurements, verify that you have performed the following setup and
configuration processes:
• “Loading and Running the Test Software” on page 23
• “Operating the BTS Laptop Utility Program” on page 27
• “Connecting the PC to the Test Set and the MSC” on page 31.

Calibrating the Test Setup
If you did not know the Base Station TX Antenna Port Cable Loss, or the Base Station
TX Test Port Cable Loss, or the Base Station TX Coupler Losses when you entered the
data on the Base Station Configuration Menu screen, run the following calibration
routines to determine these losses. Determining these losses is crucial to obtaining
accurate test results.
Access these routines by loading and running the Test Software (see “Loading and
Running the Test Software” on page 23) and selecting Calibration/Utilities from
the Lucent AMPS Tests Main Menu screen. The Test Software will display the
Calibration/Utilities Menu screen (see Figure 4-1). After each measurement, the
program will enter the value automatically into the Test Software for future testing
(without your having to rerun the routines every time that you test). However, if you run
a different program after the measurements, you must re-measure (or re-enter) the
values the next time that you use the Test Software.
The Calibration procedures are:
• “TX Antenna Port Cable Calibration” on page 84. Run this utility to determine
antenna port cable losses at the frequency and power level at which testing will be
performed.
• “TX Test Port Cable Calibration” on page 86. Run this utility to determine test port
cable losses at the frequency and power level at which testing will be performed.
• “TX Test Port Coupling Measurements” on page 88. Run this utility to determine the
exact coupling factor (loss) of the Base Station TX Test Port.

NOTE
Before starting to run operational tests, make certain that you have set PARAMETER
32. ZZZZ Test Demo Mode [0=normal 1=demo] to 0.
You are now ready to select and run tests. On the Test Selections Menu screen, scroll to
the test that you wish to run, and press the knob to select it. The test will run. You may
then select another test and run it in the same manner. You may repeat this operation as
many times as is necessary.
After successfully running the tests, it is recommended that you save all of the
configuration information as a procedure file on an SRAM card for later retrieval (see
“Saving/Deleting a Procedure” on page 109). This eliminates the requirement for
re-entering the information if you run a different program, change parameters when
testing another Base Station, or install new operating system firmware in the Test Set.

Full Site Test (FCC)
This test measures several aspects of radio performance on one or more radios.
Measurements are made at the Base Station TX Test Ports in the Antenna Interface
Frame, eliminating the need to take an entire antenna face down during testing.
Before the test can run, you must to create a frequency plan containing information
about each radio to be tested (see “Defining a Frequency Plan” on page 43). Because the
Test Software uses the frequency plan to control automatically all of the radios under
test, this test cannot be performed using manual control of the Base Station. If you must
test a radio using manual control, use the “Single Radio Test” on page 68.
The measurements made on each radio depends on its type: AMPS or AMPS Setup. The
radio type is specified in the frequency plan.
The following measurements are made on all radios:
• TX Frequency Error
• TX Power (at a specific power amplifier step)
• TX Peak (+) Data Deviation
• TX Peak (-) Data Deviation
The following additional measurements are only made on an AMPS radio (not AMPS
Setup):
• TX RMS Residual FM
• TX Average Peak Deviation @ −16 dBm
• TX Distortion @ −16 dBm
• TX Peak (+) Deviation @ 0 dBm
• TX Peak (−) Deviation @ 0 dBm
• TX SAT Average Peak Deviation @ 0 Hz
• TX SAT Frequency Error @ 0 Hz

TX –39 dBm Power Test
This test provides the process by which all radios are adjusted to produce drive signals to
the linear amplifier circuit (LAC) that are approximately equal and within the proper
range. This test uses information from the frequency table to determine which radios are
applicable for the test.
If you select a reference radio, the basic procedure performed in this test is as follows:
• Select one reference radio for each equipped antenna per LAC. If possible, select the
farthest right-hand voice radio (not setup radio) in shelf 2, 3, or 4 of the primary radio
channel frame (PRCF). If there is an antenna in the PRCF that does not have an
associated transmitting radio, select the farthest right-hand radio in shelf 2, 3, or 4 of
the growth radio channel frame (GRCF) as the reference radio for that antenna.
• Connect a test cable of known loss to the Test Set ANT IN port. Connect the other end
of the test cable to the Base Station TX SIG MON jack corresponding to the first
reference radio.
• The command config multi radio is issued to the Base Station to turn on all radio
transmitters.
• Turn off all radios by switching the AUTO/OFF switch to OFF.
• Turn on the reference radio by switching the AUTO/OFF switch to AUTO. Adjust the
potentiometer on the reference radio front panel for a −39 dBm TX SIG MON output.
Once power is set, turn off the reference radio by setting the AUTO/OFF switch to
OFF. Disconnect the Test Set from the SIG MON jack.
• Remove the Test cable. Connect a test cable between the Base Station Antenna
Output and the Test Set RF IN/OUT port.
• Turn on the reference radio. Adjust the LAC preamplifier for maximum power, for
minimum power, and finally to the desired power as defined in the frequency plan for
the reference radio. Turn off the reference radio.
• The next series of steps is to turn on the radios, one at a time, set the power of each
radio using the potentiometer on the radio front panel, and then turn off the radio.
The power is determined by the power setting defined for that radio in the frequency
plan.
• Once the power has been set on all radios, the restore commands are issued to the
radios to turn off all transmitters.
• Disconnect the cable between the Base Station Antenna Output and the Test Set.
Reconnect the Base Station Antenna Output to the foam jumper.

Step 7. Scroll to the Use Reference Radio field and press the knob to toggle it to the desired
mode.
If you select YES, the Test Software will lead you through a step-by-step process that
uses one radio in the face to set a −39 dBm reference level at the TX SIG MON jack. The
reference level becomes a known good drive level input to the LAC preamplifier. This
allows the LAC preamplifier to be adjusted properly for the desired output level. Once
the LAC preamplifier is adjusted properly, all other radios may be adjusted by simply
setting the potentiometer on each radio front panel.
Also, if you select Yes, the Do you need assistance? field will appear immediately
below. Press the knob to toggle the field to the desired setting. If you understand the
testing process and wish to have the Test Software perform it as automatically as
possible, select No. If you wish to have the Test Software display informational screens at
appropriate points in the testing process to assist you in performing the operations,
select Yes.
If you select NO, the Test Software will assume that the LAC preamplifier is adjusted
properly for the power level for the face and the power output for each radio defined in

TX Test Port Coupling Measurements
TX Test Port Coupling Measurements
This utility measures the loss associated with testing from a Base Station TX Test Port.
This provides to the Test Software a coupling factor to use with measurements from that
Base Station TX Test Port. Repeat this measurement for each test port to be used at the
cell site.
At the start of the test, you must full or partial calibration.
• In Full calibration, the Test Software first measures the level at the Base Station TX
Antenna Port, then the level at the Base Station TX Test Port. It uses the difference
between these levels to determine the loss through the TX Test Port.
If you have connected and configured a PC for automated control of the Base Station,
the Test Software will send commands to the MSC during the test. If you wish to use
manual Base Station control, you must disable call processing and turn off any
transmitters prior to connecting the Test Set to the Base Station TX Antenna Port.
NOTE
During full calibration, the Test Software will prompt you to connect the Test Set RF
IN/OUT port to the Base Station TX Antenna Port using the TX Antenna Port cable.
After you have done so, the Test Software will prompt you to connect the Test Set
ANT IN port to the Base Station TX Test Port using the TX Test Port cable.
For accurate TX Test port calibration, you must use the correct cables when
prompted.
• In Partial calibration, the Test Software will use a Reference Power Level (that you
must enter) to determine the coupling factor. This is the level out of the Antenna
Interface Frame that feeds the foam jumper to the transmit antenna. The Test
Software then measures the level at the Base Station TX Test Port is measured and
uses the difference in these levels is used to determine the loss through the TX Test
Port.
Unless you are certain that the Reference Power Level that you enter is correct (± 0.5
dB), you should use the full calibration for the most accurate results.

BTS Laptop Utility Program Windows
The BTS Laptop Utility program provides five windows in which information may be
display or entered. These windows are: Switch Terminal, Test Set Terminal, Other
Data, Test Results, and Test Set Screen Capture.
For information on installing the BTS Laptop Utility program and configuring the PC
and Test Set to work together, see “Operating the BTS Laptop Utility Program” on page
27.
The Switch Terminal window functions as essentially a VT100 terminal to accomplish
the following:
• It allows you to connect with the MSC, either with the PC internal modem to dial into
the MSC, or with the PC and a telnet connection to the MSC.
• It displays the commands sent to the MSC and the replies sent back from the MSC.
Test Set Terminal Window
The Test Set Terminal window displays commands sent from the Test Set to the MSC.
Other Data Window
The Other Data window accomplishes the following:
• It allows you to download frequency plans to the Test Set.
• It displays short-form test results.
The short-form test results are sent to the PC automatically and displayed in the
window (see Figure 5-16 for an example of the display). By selecting File, Logging
Enabled, you may enter a file name to save the test results to a file that may be
retrieved into a text editor and printed out. This selection must be done before the
test results are sent to the screen.

Demo (Demonstration) Mode
Demo (Demonstration) Mode
The demonstration mode offers a good method for becoming familiar with the operation
of the Test Software. Demo mode allows you to step through the menus and simulate
testing without a PC, a connection to the switch, or even a Base Station.
In the demo mode, the system will not send commands to the MSC, but it will perform
very much the same as if actually testing a Base Station. When measurements are
displayed, it provides sample numbers in order to show how the printout format will
appear.
There are two methods for entering the demo mode:
• Selecting the procedure named DEMO.
and
• Selecting the demo mode using the demo control parameter (see 32. ZZZZ Test Demo
Mode [0=normal 1=demo]).
Selecting the DEMO Procedure
Select the DEMO procedure as follows:
NOTE
Once the DEMO procedure is loaded, it will remain in the Test Set memory until you load
another procedure. Even if you turn off the Test Set and run the Test Software later, the
procedure is stored in battery-backed-up memory and will remain ready to run.
Step 1. If the Test Software is running, press the Shift key, then the Pause/Continue key to stop it.
Step 2. Press the Menu key. The Test Software will display the SOFTWARE MENU screen.
Step 3. Select the Select Procedure Location: field, then select Card from the drop-down

Parameters
Parameters
The Test Software uses the entries in the Test Parameters screen to customize testing
and specify serial communications settings.
A special parameter allows the Test Software to run in a demonstration mode, which is
useful for familiarization with the operation of the Test Set without connecting to any
external equipment (see “Demo (Demonstration) Mode” on page 116).
Most parameters may be entered in two ways:
• By loading and running the Test Software and entering all of the information in the
Test Configuration, Base Station Configuration, and Serial Port Configuration
menus. The Test Software automatically changes the test parameter settings to
match the configuration settings.
Parameters that may not be set while the Test Software is running include:
— 1. Adjust TX Power [0=no 1=on fail 2=always]
— 2. GN MSC Command Speed [0=slow 1=fast]
— 4. GN Stop Test if results fail [0=no 1=yes]
— 20. MSC Require CP INH at Ant Port [1=Yes]
— 31. TX Use 230 kHz BW on Data Dev [1=yes]
— 32. ZZZZ Test Demo Mode [0=normal 1=demo]
• By loading the Test Software and selecting Parm Test Parameters on the main
SOFTWARE MENU screen. You may change the settings from the factory defaults.
This section lists the parameters and describes the use of each. For instructions on
changing the parameters and saving the changes on an SRAM card, see “Changing Test
Parameters” on page 103 and “Saving/Deleting a Procedure” on page 109.
1. Adjust TX Power [0=no 1=on fail 2=always]

31. TX Use 230 kHz BW on Data Dev [1=yes]
Enter the selection to determine which of the filters in the Test Set will be used in
data deviation measurements in either the Single Radio Test or Full Site Test.
• If you select 1, the 230-kHz filter will be used. This is the default selection.
• If you select 0, the 30-kHz filter will be used.
When using the 230-kHz IF filter, the Base Station must not be transmitting another
signal within seven channel spacings (210 kHz) above or below the signal being
measured; otherwise the measurement will be in error. In Figure 5-18, the Spectrum
Analyzer and delta marker functions are used to illustrate that another signal could
interfere with the measurement. (See the Reference Guide for information on using
the Spectrum Analyzer).
It is preferable to use the 230-kHz filter when possible. However, if it is not possible
to turn off a transmitter that is within 210 kHz of the signal to be measured, use the
narrow (30-kHz) filter.

Specifications (Pass/Fail Limits)
Specifications (Pass/Fail Limits)
The Test Software uses the entries in the TESTS (Pass/Fail Limits) screen to determine
if a measurement meets the test requirements. If not, it displays a “fail” indication in the
results display (and, in some instances, provides for adjustments and re-test).
This section lists the specification limit names and explains how each is used. For
instructions on changing the pass/fail limits and saving the changes to an SRAM card,
see “Changing Pass/Fail Limits” on page 106 and “Saving/Deleting a Procedure” on
page 109.
1. AMPS Data Peak Deviation
Enter the upper and lower deviation limits, in kHz.
The 1004-Hz test signal in the Base Station is sent to the data modulator in the radio
and the Test Software measures the resulting peak deviation and compares the result
with the limits.
2. AMPS Deviation at -16 dBm Audio Level
Enter the upper and lower deviation limits, in kHz.
The 1004-Hz test signal in the Base Station is set to a level of -16 dBm, and is then
sent to the analog modulator in the radio. The Test Software measures the resulting
deviation and compares the result with the limits.
3. AMPS Deviation at 0 dBm Audio Level
Enter the upper deviation limit only, in kHz.
The 1004-Hz test signal in the Base Station is set to a level of 0 dBm, and is then sent
to the analog modulator in the radio. The Test Software measures the resulting
deviation and compares the result with the limit.
4. AMPS Distortion at -16 dBm Audio Level
Enter the upper distortion limit only, in percent (%).
The 1004-Hz test signal in the Base Station is set to a level of -16 dBm, and is then
sent to the analog modulator in the radio. The Test Software measures the resulting
distortion is compares the result with the limit.
5. AMPS Frequency Error
Enter the upper and lower limits, in Hz.
The Test Software measures the transmitter center frequency and compares it with
the ideal frequency, based on the entry for channel number. The difference between
the two is the frequency error. The Test Software then compares the calculated
frequency error is then compared with the limits.
6. AMPS Residual FM [15 Hz - 15 kHz]
Enter the upper and lower limits, in Hz.
With all modulation turned off, the Test Software measures the amount of FM
present in the rf carrier from the radio.

Specifications (Pass/Fail Limits)
7. AMPS SAT Frequency Error
Enter the upper and lower limits, in Hz.
The Test Software measures the difference between the measured SAT frequency and
the SAT frequency specified in the Base Station Configuration Menu, and compares
the result with the limits.
When testing all SAT frequencies, the Test Software changes the SAT frequency to
measure each frequency in sequence, using the same frequency error limits for all
measurements.
8. AMPS SAT Peak Deviation
The Test Software measures the peak deviation for the SAT with all other modulation
turned off, and compares the result with the limits.
9. Output Power Adjustment Error
Enter the upper and lower limits, in dB.
These limits determine how the power meter will be displayed. When the power
meter display is displayed, it includes major tick marks that indicate the adjustment
range for power settings. If you enter ±1 dB as the limits, the meter will be drawn
with the ideal setting in the center and major tick marks 1-dB up and 1-dB down
from center.
10. Output Power Error
Enter the upper and lower limits, in dB.
While the previous limits (Output Power Adjustment Error) controlled the
adjustment diagram in power meter use, the Output Power Error limits determine
whether the power measurement made in automated testing meets specifications. If
you set Output Power Error limits of ±2 dB, these limits will be used when a power
measurement is made. If the power measured is more than 2 dB from the desired
setting, a fail indication (F) will result.
NOTE
Chapter 5
In general, it is best to set the Output Power Adjustment Error limits set narrower
(smaller) than the Output Power Error limits.

Testing without MSC Control
Testing without MSC Control
Chapter 4, “Performing Tests,” on page 59 lists the steps for fully automated testing,
using the Test Software to control the Base Station. The steps of that chapter use a PC to
control the Base Station via the MSC.
If you are using a Test Set setup with no PC and connection to the MSC, the following
considerations apply:
• Make certain to set the Send Control Commands to MSC field on the Base Station
Configuration Menu to NO. The Test Set will not send control commands to the MSC
using the PC.
• The connection diagrams at the start of each test sequence will include prompts to
apply or remove power for the BBA being tested. You must control the transmitter
signal (on and off) manually at the site.
• You will probably require an assistant at the MSC to control the Base Station and
remove the radios from service.

Using a PC Card
Using a PC Card
Before a PC card may be used for the first time, it must be initialized. The following tow
sections describe the initialization process and offer some troubleshooting information in
the event of a problem with the use of a PC card.
Initializing a PC Card
Step 1. Insert the PC card into the front-panel card slot
Step 2. If a Test Software package is running, press the Shift key, then the Pause/Continue key to
stop it.
Step 3. Press the Shift key, then the Inst Config key. The Test Set will display the I/O
CONFIGURE screen.
Step 4. Select the Format Card field. The Test Set will display a query asking if you wish to
“Erase and format the PCMCIA Card?” (YES/NO).
Step 5. Press the Yes On/Off key, located below and to the right of the knob, to format the card.
The card is formatted when the cursor stops blinking.
Troubleshooting PC Card Use
Each of the messages listed below is followed by an explanation of the probable cause.
Directory Overflow.
• The SRAM card is probably full and cannot store new files. You might have to delete
some files on the card to clear memory space or use a new PC card.
Medium uninitialized. Do you want to initialize?
• The card either not been initialized or has other information stored on it. Initializing
overwrites any data that might already be on the card. Press the Yes On/Off key to
initialize the installed card.
Write protected.
• The card has been write protected (the switch in the WP position). Slide the write
protect switch into the other position before writing.
Medium changed or not in drive. No information was loaded.
• The card has possibly not been inserted properly. Re-insert and try again.

Troubleshooting the Test Software Installation
Troubleshooting the Test Software Installation
If the Test Software did not install properly, check the following:
• Is the power on?
• Is the PC card inserted in the correct orientation?
• Is the PC card firmly seated in the slot? It should slide in loosely, then be firmly
pushed in to make proper contact.
• Did the SOFTWARE MENU screen appear? Pressing the front panel Preset key
should display the SOFTWARE MENU screen.
• Did TESTS (IBASIC Controller) appear at the top of the display after you pressed the
k1 (Run Test) key? If not, make certain that you have specified the correct Procedure
Location and Procedure Filename.
If you were unable to load and run the Test Software, make the required entries, or you
encountered error messages, refer to other sections of this chapter.

Troubleshooting
Errors When Loading and Running the Test Software
Errors When Loading and Running the Test Software
This group of errors would most often be encountered before the Main Menu appears.
Such errors would be most likely to occur the first time that you load and run the Test
Software (see Chapter 2, “Installation,” on page 21). The errors are presented with the
error text, followed by a description of the cause, followed by some possible solutions.
❏
Symptom: Memory Overflow Errors
The random access memory (RAM) space of the Test Set is shared by IBASIC
programs and save/recall registers. If you have saved a large number of registers
in the Test Set, a memory overflow error might occur when you first attempt to
load the Test Software.
To correct this, clear some RAM space by deleting some or all of the saved
registers. You may do this selectively (one register at a time) or globally (all
storage registers at once).
NOTE
Clearing the registers, whether selectively or globally, is permanent. Registers are not
retrievable once deleted. You may save registers to an SRAM card, as well. Refer to
the Agilent Technologies 8935 Reference Guide for instructions on this procedure.
To delete a single register:
Step 1. Press the Recall key.
Step 2. Scroll the cursor to the register to be deleted.
Step 3. Press the Yes On/Off key to indicate that you wish to clear the register.
Step 4. Press the Yes On/Off key again to confirm.
Step 5. The register will be cleared.
To delete all saved registers:
Step 1. Press the Recall key.
Step 2. Scroll to *Clr All* and press the knob.
Step 3. Press the Yes On/Off key to confirm.
Step 4. All save registers will be cleared.

Communication Errors
Communication Errors
Errors When First Setting Up or Connecting to MSC
• Message: Base Station did not answer...
If commands are misunderstood at the MSC end, this error message might occur. Use
the Switch Terminal window in the BTS Laptop Utility program to send commands
and view responses to identify the problem command. Also, refer to “Troubleshooting
Checks for Communication Problems” on page 134 for a list of items to check when
you have noticed this error.
Communication Errors During Testing
Message: Lost the modem carrier. Use the BTS Laptop Utility program to correct the
problem and to return all configured BBAs back to active status. Press the Abort key to
return to the main menu.
This error indicates that communication with the MSC was taking place, but the link
was lost sometime during the testing process.
Also check the items in “Troubleshooting Checks for Communication Problems” on page
134 for possible causes of interruptions to the communication between the Test System
and the MSC.

Communication Errors
Troubleshooting Checks for Communication Problems
The following list provides items to check when you are having communication
difficulties using the external modem to connect to the MSC.
❏ Cable connections:
Make certain that you have made the proper connections between the Test Set serial
port, the phone line or telnet connection, and the personal computer (PC).
A list of cables and part numbers is provided in “Optional Accessory Kits” on page
17.
❏ Dialing difficulties:
In some cases, you might have to customize the dialing information in order to
properly dial and connect to the MSC. For example, if there is a 9 in the dialing
sequence to obtain an outside phone line, there might be a short delay before the dial
tone is heard. Therefore, a delay after the 9 might be required before the rest of the
digits in the sequence are sent. This may be done from the Switch Terminal window
of the BTS Laptop Utility program. Clicking on the Dial button on the Switch
Terminal window tool bar, and add a comma between the numbers as shown in the
following example.
9, 1-509-835-0000
❏ MSC is not configured to send responses to commands:
After sending a control command to the MSC, the Test Software searches for response
commands from the MSC before continuing. It might be that the MSC with which the
system is communicating has been configured to not send responses to remote
computers. You might have to check with a switch technician to determine if this is
the case for the MSC in question.

Errors While Attempting Measurements
Errors While Attempting Measurements
The following error messages might be posted once a test mode has begun making
measurements:
• Full Site Test (FCC) is selected but does not run.
The Full Site Test uses a frequency plan to provide the required cell site and radio
information. If the Test Software cannot locate a frequency plan, it exits the test. See
“Defining a Frequency Plan” on page 43 for information on the contents and creation
of frequency plans.
• The indicated TX Power level is very low or very high.
Assuming that the radio is transmitting at the proper level, this problem is usually
caused by incorrect parameter entries dealing with test cable and test port losses.
If testing at the Base Station TX Test Port:
— Verify that the Base Station Connection field on the Base Station
Configuration Menu is set to TX Test Port.
— Verify that the Base Station TX Test Port is connected to the Test Set ANT IN port
(as shown in the setup drawing that appears at the start of the test).
— Measure the Base Station TX Test Port Cable Loss and enter it on the Base
Station Configuration Menu. See “TX Test Port Cable Calibration” on page 86.
— Verify that you have entered the correct VRAL/CSAC setting for the selected radio
at the start of the test.
If testing at the Base Station TX Antenna Port (foam jumper):
— Verify that the Base Station TX Antenna Port is connected to the Test Set RF
IN/OUT port (as shown in the setup drawing that appears at the start of the test).
— Verify that the Base Station Connection field on the Base Station
Configuration Menu is set to TX Antenna Port.
— Measure the TX Antenna Port Cable Loss and enter it on the Base Station
Configuration Menu. See “TX Antenna Port Cable Calibration” on page 84.
— Verify that you have entered the correct VRAL/CSAC setting for the selected radio
at the start of the test.
