1 Getting Started
What is CAIT?
The QCTestTM
CDMA Air Interface Tester (CAITTM
) is a testing and
analysis tool that logs and displays call information going over the
air to and from a mobile phone in a cellular network. It allows you
to view, collect, and manage phone status, operating parameters,
and messages. The application runs on an IBM-compatible personal
computer (PC) connected by a serial link to a mobile phone. You can
use CAIT to do the following:
■ View and evaluate network conditions using the Temporal
Analyzer, Signal Graphs, and PN Scanner displays
■ Collect call performance statistics
■ Report diagnostic messages (when the message feature is
enabled in the phone)
■ Log over-the-air (OTA) messages
■ Log position data from a Global Positioning System (GPS)
receiver (when installed)
■ Replay log files for further analysis
■ Control and automate phone testing from CAIT using a large set
of scripting commands or the Call Monitor display
■ Collect data to help you evaluate the performance of over-the-air
data calls
■ Define your own data display windows that combine log
message values you want to track with formulas and functions
that format the data to meet your specific needs
■ View real-time map displays of logging data containing GPS
coordinates
CAIT uses a serial communication protocol that connects the PC to
several different types of mobile phones, asynchronously, via serial

interface, at either 19.2, 38.4, 57.6, or 115.2 kbps. CAIT can test a
variety of phones based on the QUALCOMM chipset and on
QUALCOMM diagnostic software.
CAIT supports the following GPS protocols:
■ NMEA (National Marine Electronics Association 0183 protocol)
■ TAIP (Trimble ASCII Interface Protocol)
■ ETAK (The old poll and response ETAK, not the newer ETAK)
System requirements
The following table describes the hardware items and operating
system required to operate the CAIT system. If your current setup
meets or exceeds these requirements, then no upgrade is necessary
to use CAIT.
Item Description
Computer Desktop or laptop computer; 500 MHz Pentium III
minimum, 800 MHz Pentium III recommended.
Note: This configuration is adequate for use with a
single test phone connected. For running multiple
instances of CAIT for use with multiple test phones (see
“Installing for multiple phones” on page 6), a faster
processor speed and more RAM is recommended.
RAM 128 MB minimum, 256 MB or greater recommended.
Hard drive Application requires 40 MB or greater. An additional
36 MB per hour is used when generating log files at full
rate.
Operating system Windows 2000, Windows XP
or
Windows NT 4.0 Service Pack 5 or higher.
Serial
communications
A free serial I/O port (two if using GPS) or USB
connection.
Additional port A parallel port, USB port, or PCMCIA slot is required for
attaching the copy protection key hardware.

GettingStarted
Requirements for throughput performance testing
The minimum system requirements mentioned in the previous table
may not be sufficient for throughput performance testing. When you
use QCTest CAIT with a data phone or terminal during a data call,
it is recommended that a high-performance system be used. Such a
system is necessary to achieve the highest throughput possible while
maintaining a diagnostic link with the phone or terminal.
For example, when testing the 1xEV Forward Link throughput
performance at the maximum allowable rate of 2.4 Mbps, the
following configuration is recommended:
■ Pentium 3 1066 MHz CPU or better
■ 512 MB of RAM or better (for a single instance of QCTest CAIT)
Setting up CAIT
CAIT installation occurs in the following stages:
1. Connecting the mobile phone to the computer
2. Connecting the security key
3. Installing the CAIT software and permission file
4. Initial startup
This section contains the information needed for initially setting up
and configuring the CAIT system. For information about your
computer or mobile phone, refer to the user’s guide provided for
that product.
Note To install CAIT on Windows NT, Windows 2000, or Windows XP you must have
Administrator privileges for the system. Once CAIT is installed, you can run it
from any user account. Contact your computer support organization if you need
Administrator privileges granted.
PC-to-phone
connecting cable
PC-to-phone serial interface cable. Users of
non-QUALCOMM made handsets must acquire serial
interface cables from their phones’ manufacturer. See
“Connecting phones” on page 4 for more information.
Copy protection WIBU®
security key, QUALCOMM model DAMST0050,
DAMST0052, or DAMST0053
Item Description

If you need more information or assistance during system setup,
please contact QUALCOMM Technical Support as described in
“Technical support” on page xiv.
Connecting phones
Before installing CAIT, you should connect a mobile phone to the
computer using a serial or USB connector cable that is appropriate
for that phone. There are some considerations that you should keep
in mind when selecting such a connector, which concern the fact that
the test phone can communicate with the PC via two separate
protocols:
■ DIAG, the diagnostic protocol, which CAIT uses to
communicate with the test phone during any type of call
■ DATA, the modem protocol, which other programs can use to
originate calls by sending AT commands to the phone
Most phones on the commercial market today that are based on a
QUALCOMM chipset support the DIAG protocol over the primary
UART (UART1) via a RS-232 DB-9 serial connection.
With the MSM5500 and subsequent chipsets, the DIAG protocol can
be mapped to a USB connection, allowing simultaneous access to
DATA and DIAG protocols. If you are using a test phone based on
MSM5500 or greater that was not manufactured by QUALCOMM,
please contact that phone’s manufacturer to find out if they have
implemented support for DIAG over USB, and if so, how to obtain
the USB drivers they approve for use with their device.
QUALCOMM does not distribute USB drivers for other handset
manufacturers, even though they use a QUALCOMM chipset.
Commercial phones based on earlier MSM chipsets (MSM3100
through MSM5105) may include a USB data cable, but those phones
may support only the DATA mode over USB, while DIAG mode
remains on UART1. With these types of phones, it is possible to
switch the USB connection between DATA and DIAG modes, but
doing so does not provide simultaneous access to DATA and DIAG.
QUALCOMM has teamed up with handset manufacturer Kyocera
Wireless Corporation to develop a Dual Port Adaptor for their
handsets, which allows DATA and DIAG to be mapped to UART1
and UART2, respectively. This special piece of hardware goes
between the host PC running CAIT and the test phone, and allows
for simultaneous DATA and DIAG mode access. For more

GettingStarted
information on this product, visit QUALCOMM’s web site at
http://www.qualcomm.com/qctest/products/dpak.html.
Connecting the security key
CAIT is copy-protected through the use of security key hardware
and corresponding driver software. The security key is a WIBU®
type or equivalent. There are three types of key available:
■ Parallel port, model number DAMST0050
■ USB Port, model number DAMST0052
■ PCMCIA card, model number, DAMST0053
To connect the security key to the CAIT computer, attach it to the
appropriate port on your computer. If you use the parallel or serial
port model, you can then attach any other cable or hardware that
was previously attached to the port to the pass-through connector
on the key.
For the security key to run properly, you must install the WIBU-KEY
driver software along with the CAIT application software. To do
this, select the Install Security Key option from the CAIT CD’s
autorun menu.
Licensed CAIT users who have issues with broken or lost
copy-protection devices should contact QUALCOMM Technical
Support as specified in “Technical support” on page xiv.
A “Network Server” feature is also supported by the WIBU-KEY
driver software. This feature allows multi-license “network” keys to
broadcast available CAIT licenses across a LAN. Single license keys
will not function across a network in this way. If you wish to
upgrade your single license key to a network key supporting one or
more licenses, please contact your QCTest Account Manager, or
send email to qctest-info@qualcomm.com. You will need to have a
new key issued to you, as the part number of the key is different for
logistical and tracking purposes.

Installing CAIT software
Before installing CAIT as described in “Installing CAIT” on page 6,
read the following section on the multi-phone installation option in
CAIT.
Installing for multiple phones
The installer has the ability to set up multiple instances of CAIT,
which lets you operate multiple test phones connected to your
computer.
To take advantage of this feature, select the Custom installation type
(as opposed to Typical or Compact). Selecting this option presents
you with an expandable list of selectable component options. In this
list, select the check box for each serial port to which a test phone
might be connected.
When installation is completed, the Start menu folder for CAIT
contains a separate shortcut to CAIT for each port that was selected.
Installing CAIT
To install the CAIT software, do the following:
1. Insert the CAIT CD into your CD-ROM drive. From the autoplay
menu that appears, select Install CAIT. If the autoplay feature
isn’t enabled on your computer, double-click the Autoplay.exe
program in the CD’s root directory.
2. To continue the installation, follow the instructions provided by
the installer.
When the Setup Complete dialog box appears, the application
has been installed successfully.
3. To complete installation, click Finish or press Enter.
Installing the CAIT permission file
Your CAIT software distribution includes a 3.5-inch diskette
containing your customized QUALCOMM permission file (ending
in a .QPF extension). To enable all CAIT features that your license
supports, copy the permission file to the directory where you
installed CAIT.
The permission file diskette includes directions for placing the
permission file, as well as a small batch file that you can run to place
the file in the default CAIT installation directory.

GettingStarted
Starting CAIT for the first time
Before starting CAIT, connect the test phone and, optionally, GPS
receiver to your computer’s serial ports. Also be sure that the copy
protection key is attached and the permission file is in place.
To start CAIT for the first time, do the following:
1. Power up the test phone.
2. From the Start menu, select Programs : QCTest CAIT : QCTest
CAIT.
The application automatically loads. At this point, CAIT is
operating normally and can perform any test functions needed.
If the application fails to start and operate normally, verify that
the test phone and copy protection key are correctly installed
according to the instructions in “Setting up CAIT” on page 3.
By default, CAIT expects the phone to be attached to COM1. If it
is attached elsewhere, you will need to configure CAIT to look
for it on the appropriate port.
Note If you need information about setting the configuration parameters for CAIT, see
“Configuring CAIT” on page 197.

CAIT main window
The CAIT main window is the primary user interface for viewing
and controlling mobile phone functions, as well as for logging and
displaying call data. It allows you to open and manipulate files;
select options, views, and subordinate windows; display temporal
analyzer and signal graphs information; and get online operating
instructions.
The CAIT main window consists of the main menu bar, viewing
area, and customizable status bar. Several controls, such as
minimize, maximize, and scrolling, allow you to open or close
various menus and displays, and change how the window appears.

CAIT status bar
The Customizable status bar in CAIT lets you decide which
information you want to see, at a glance, at the bottom of the CAIT
window. This status bar shows as many individual status boxes as
the window’s current size will allow. To change the information
shown in any one of these boxes, click the arrow at the right of the
box, and choose the information you want displayed from the
resulting menu.
Sometimes notices will scroll over the status bar area, most notably
when the CAIT license is within 30 days of expiring.
CAIT session transcript
The CAIT Session Transcript window displays messages generated
by CAIT during its run time.
In addition to messages generated by the alarms you define (see
“Configuring event-based alarms” on page 216), messages about
test phone connections as well as copy-protection key and
permission file issues are listed in this window.

GettingStarted
Buttons in this window let you clear the current transcript contents
or save them to a file. You can also have CAIT save the transcript to
a file automatically, when it exits (see “Configuring CAIT” on page
197).
A check box, Don’t warn me about expirations, keeps
license-expiration warnings out of the transcript when enabled
(checked).
Capturing CAIT displays
CAIT provides a screen capture feature that lets you save snapshots
of the CAIT window or its component displays as bitmap (BMP)
files.
■ To capture the contents of the entire CAIT window, from the
Capture menu, select CAIT Screen. Or, press Ctrl+P.
■ To capture the contents of the currently active CAIT window,
from the Capture menu, select Current Window. Or, press
Shift+Ctrl+P.
After capturing the window snapshot, CAIT displays a Save As
dialog box so that you can specify how to save the file. Click Save to
complete the screen capture.
You can also capture CAIT displays using the
SAVE_CAIT_SCREEN scripting command, as described in
“SAVE_CAIT_SCREEN” on page 286.

Pausing CAIT displays
CAIT lets you pause its real-time event displays whenever you need
to review or capture a specific reading. A traffic-light icon on the
Icon Bar lets you click to pause the action in all active displays. When
clicked, the icon turns from red to green, to indicate that re-clicking
it will resume the display of event processing.
This Pause/Resume functionality is also available on the Options
menu, and via two hot-key combinations: Ctrl+S to pause and
Ctrl+Q to resume.
CMML in CAIT
The logging messages that CAIT processes are defined using
QUALCOMM’s CDMA Messages Markup Language, or CMML.
CMML is a metadata representation of the signaling messages
defined by CDMA, WCDMA, and GSM standards, as well as the
logging and diagnostic messages reported by test phones that
support those standards.
Metadata has been traditionally understood to be “data about data.”
In this case, it is XML data that describes CDMA signaling, logging,
and diagnostic messages.
XML, or eXtensible Markup Language, is a meta-language for
creating specialized markup languages. That is, XML is a language
for defining markup language elements, or tags, and the structural
relationships between them. In this way, CMML is defined by XML.
For more information on XML, you may want to look at the
specification maintained by the World Wide Web Consortium
(W3C) at http://www.w3.org/TR/REC-xml.
Upgrading CAIT
Occasionally, CAIT is upgraded to include corrections,
enhancements, and new features. Licensed users of CAIT who have
registered the application are notified of any new upgrade. Current
information about CAIT is available at any time from
QUALCOMM’s QCTest Technical Support. See “Technical support”
on page xiv for contact information, or visit the QUALCOMM Web
site at http://www.qualcomm.com

SignalAnalysis
2 Signal Analysis
Overview
CAIT contains several different windows that provide graphic
displays of mobile phone signals. The Temporal Analyzer window
tracks the strength and arrival times of the multipaths of those
signals from sectors in the phone’s Active (and, optionally,
Neighbor) set. CAIT also supports QUALCOMM’s Retriever™ pilot
scanner phone when CAIT is in Retriever mode (see “Configuring a
Retriever phone” on page 209). The Signal Graphs window displays
various characteristics of the transmit and receive signals from the
mobile phone. The PN Grid and PN Graph windows display signal
activity at every PN offset or in a regular sampling of PN offsets
when used with the Retriever pilot scanner.
Temporal Analyzer window
The Temporal Analyzer window displays graphs or line plots of
active signals and neighbor signals for a mobile phone under test.
This window shows signal power relative to the time offset in PN
(pseudo noise) chips. With the Temporal Analyzer, you can do the
following:
■ View signal levels above or below the noise floor
■ Increase or decrease the grid scale of the time offset or horizontal
axis of the display
■ Increase or decrease the limit for the transmit (Tx) power control
■ Configure the Temporal Analyzer display

16 Chapter 2: Signal Analysis QUALCOMM Proprietary
You can use the Temporal Analyzer menu in the CAIT main
window to change power level and time offset settings for the
display. To view the Temporal Analyzer window, select Temporal
Analyzer from the View menu or press the F2 key.
This section provides detailed information about using the
Temporal Analyzer.

Viewing displays
The Temporal Analyzer window shows multiple traces in different
colors (when the colors are set up on the Configure Cells dialog
box—see “Configuring cells” on page 206). Each trace represents the
sweep signal of a mobile phone searcher. The window displays a
grid with horizontal and vertical axes that are divided into two
different scales.
When the signal traces on the window stabilize and average, you can
determine the timing and power of the signals by using the X- and
Y-axis scales of the display.
The horizontal or X-axis represents the time offset with a scale in
pseudo noise (PN) chips. The vertical or Y-axis represents the signal
power level or strength with a scale in decibels (dB) for the energy
per chip over the interference noise (Ec/I0). The horizontal scale
ranges from ±12 to ±96 chips, and the vertical scale ranges from 0 to
−40 dB.
Special indicator symbols are displayed to represent the signal
peaks for up to twelve fingers (demodulators). The number of the
finger is listed inside a diamond at the top of the indicator. A circle
at the bottom of the symbol surrounds the exact finger position.
For 1xEV phones, the circle surrounding the finger position is filled
(a solid dot) when the finger is locked. When no fingers
(demodulators) are assigned, these symbols do not appear with any
of the signal peaks. This is the case when using QUALCOMM’s
Retriever™ Pilot Scanner phone in scanning mode. (See
“Configuring a Retriever phone” on page 209 for more information
about using this phone.)

SignalAnalysis
At the bottom of the Temporal Analyzer window are four text boxes
displaying signal information as described in the following table.
Item Description
Window Address The address of the center of the search window. The
least significant 16 bits are in hexadecimal, for
example, 0x2D30.
Time Scale Indicates the time or X-axis using PN scale, for
example, +/−24 chips.
View Mode Shows whether the Temporal Analyzer displays the
Active sectors only, or Neighbor sectors as well.
Sample Average The number of samples being averaged for the display.
Ranges from 1 to 128.

Toggle display under noise floor
The Temporal Analyzer can display tracked signals relative to the
level of the noise floor in the operating environment. The noise floor
is the upper boundary or average limit of the ambient noise (I0)
density.
The Temporal Analyzer uses the configurable noise threshold to
limit display of Ec/I0 below the threshold value—that is, values
under the noise threshold are “clipped” to the noise threshold. The
Toggle Display under Noise Floor menu option toggles the range of
the display of the Temporal Analyzer. When the option is enabled
(checked), the display expands as the user changes the threshold so
that the corresponding value of Ec/I0 is always at the bottom of the
graph. When the option is disabled (unchecked), the bottom of the
graph corresponds to the value -40 dB Ec/I0, independent of the
noise threshold setting.
To toggle the Temporal Analyzer display, do the following:
1. In the View menu, click Temporal Analyzer or press F2 to open
the Temporal Analyzer window with all plot lines above the
noise floor.

SignalAnalysis
2. To switch to the display with the plot lines below the noise floor,
click Toggle Display Under Noise Floor in the menu or press H.
3. To switch back to the display with signal plot lines below the
noise floor, click Toggle Display Under Noise Floor in the menu
or press H.
Increase or decrease scaling
The Temporal Analyzer lets you change the scale of the time offset
or X-axis of the tracked signals in the display. You can either
increase or decrease the time-offset scaling in increments of a factor
of two. The range goes from a minimum of +/−12 chips to a
maximum of +/−96 chips. Changing the scale lets you zoom the
display in and out around the center of the window.
To change the scaling in the Temporal Analyzer window, do the
following:
1. Select Increase Scaling in the menu or press the I key to increase
the time-offset value in the display.

2. Select Decrease Scaling from the menu or press the D key to
decrease the time-offset value in the display.
Increase or decrease power limit
The Temporal Analyzer lets you change the power limit of the signal
strength in dB shown in the display. You can either increase or
decrease the power limit scale in increments of 2 dB. The available
range is from 0 dB to −40 dB. By increasing the power limit, you raise
the pedestal of the power level, allowing the display to reduce the
number of plot lines to focus on the primary signal. By decreasing

SignalAnalysis
the power limit, you lower the pedestal of the power level, allowing
the display to show more plot lines for neighboring signals or
multipaths.
To change power limit scaling in the Temporal Analyzer window,
do the following:
1. Click Increase Power Limit in the menu or press Ctrl+I to
increase the power limit value in the display.
2. Click Decrease Power Limit in the menu or press Ctrl+D to

WCDMA Pilot Scanner window
The WCDMA Pilot Scanner window displays a bar graph of active
PSC power levels.
In the View menu, click UMTS, then Pilot Scanner to open the
window.
This window displays a vertical bar for each active PSC. The bar
representing the active set is filled with a solid color; others use a
cross-hatch fill. Numbers beneath each bar identify the PSC and
RSCP (received signal code power) displayed, and the number of
fingers represented. The power scale, in decibels, is listed at the left.
Communication status is indicated in the lower right corner.
Horizontal lines mark the upper and lower power thresholds; you
can drag to move these lines. A three-color bar on the Y-axis
indicates the colors that correspond to three power-level ranges:
■ Over the upper threshold
■ Between the thresholds
■ Under the lower threshold
You can click each segment of this bar to assign it a new color from
a Color dialog box.

SignalAnalysis
By default, the PSC power bars are assigned the color of the
power-level range they currently fall into, so that they change color
as their power level changes from one range to another. To have the
power-level bars remain the same color, regardless of their power
level, you can have CAIT color the bars according to their cell
assignment, as described below.
A context-sensitive menu is available when this window is active. By
selecting Configure from this menu, you can set options for this
display as described in the following table. Many of these options
are also available directly on the WCDMA Pilot Scanner menu.
Item Description
View Energy Toggles display of the energy values at the top of each
bar.

by the column’s values, in ascending or descending order.
Tip If you right-click in the log files pane (top right), the resulting pop-up menu lets
you toggle a Show All Files option. By default, CAIT displays in this pane only
those files that it determines are log files. Enabling this option overrides this
filtering behavior and displays all files in the selected folder, while reducing the
time required to display the files. You may want to use this option when
searching through folders that contain many files.
Note that after enabling the Show All Files option, if the first file listed is not a
CAIT-readable log file, CAIT will display a message dialog box stating that it is
not, and asking if you want to try and open it. After clicking Yes or No, you can
then select a valid log file from the list.
