  14. 14. QUALCOMM Proprietary QCTest CAIT 3.1 User’s Guide 1GettingStarted1 Getting StartedWhat is CAIT?The QCTestTMCDMA Air Interface Tester (CAITTM) is a testing andanalysis tool that logs and displays call information going over theair to and from a mobile phone in a cellular network. It allows youto view, collect, and manage phone status, operating parameters,and messages. The application runs on an IBM-compatible personalcomputer (PC) connected by a serial link to a mobile phone. You canuse CAIT to do the following:■ View and evaluate network conditions using the TemporalAnalyzer, Signal Graphs, and PN Scanner displays■ Collect call performance statistics■ Report diagnostic messages (when the message feature isenabled 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 setof scripting commands or the Call Monitor display■ Collect data to help you evaluate the performance of over-the-airdata calls■ Define your own data display windows that combine logmessage values you want to track with formulas and functionsthat format the data to meet your specific needs■ View real-time map displays of logging data containing GPScoordinatesCAIT uses a serial communication protocol that connects the PC toseveral different types of mobile phones, asynchronously, via serial

CAIT can test avariety of phones based on the QUALCOMM chipset and onQUALCOMM 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 requirementsThe following table describes the hardware items and operatingsystem required to operate the CAIT system. If your current setupmeets or exceeds these requirements, then no upgrade is necessaryto use CAIT.Item DescriptionComputer Desktop or laptop computer; 500 MHz Pentium IIIminimum, 800 MHz Pentium III recommended.Note: This configuration is adequate for use with asingle test phone connected. For running multipleinstances of CAIT for use with multiple test phones (see“Installing for multiple phones” on page 6), a fasterprocessor speed and more RAM is recommended.RAM 128 MB minimum, 256 MB or greater recommended.Hard drive Application requires 40 MB or greater. An additional36 MB per hour is used when generating log files at fullrate.Operating system Windows 2000, Windows XPorWindows NT 4.0 Service Pack 5 or higher.SerialcommunicationsA free serial I/O port (two if using GPS) or USBconnection.Additional port A parallel port, USB port, or PCMCIA slot is required forattaching the copy protection key hardware.
  16. 16. QUALCOMM Proprietary QCTest CAIT 3.1 User’s Guide 3GettingStartedRequirements for throughput performance testingThe minimum system requirements mentioned in the previous tablemay not be sufficient for throughput performance testing. When youuse QCTest CAIT with a data phone or terminal during a data call,it is recommended that a high-performance system be used. Such asystem is necessary to achieve the highest throughput possible whilemaintaining a diagnostic link with the phone or terminal.For example, when testing the 1xEV Forward Link throughputperformance at the maximum allowable rate of 2.4 Mbps, thefollowing 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 CAITCAIT installation occurs in the following stages:1. Connecting the mobile phone to the computer2. Connecting the security key3. Installing the CAIT software and permission file4. Initial startupThis section contains the information needed for initially setting upand configuring the CAIT system. For information about yourcomputer or mobile phone, refer to the user’s guide provided forthat product.Note To install CAIT on Windows NT, Windows 2000, or Windows XP you must haveAdministrator privileges for the system. Once CAIT is installed, you can run itfrom any user account. Contact your computer support organization if you needAdministrator privileges granted.PC-to-phoneconnecting cablePC-to-phone serial interface cable. Users ofnon-QUALCOMM made handsets must acquire serialinterface cables from their phones’ manufacturer.

  17. 17. 4 Chapter 1: Getting Started QUALCOMM ProprietaryIf you need more information or assistance during system setup,please contact QUALCOMM Technical Support as described in“Technical support” on page xiv.Connecting phonesBefore installing CAIT, you should connect a mobile phone to thecomputer using a serial or USB connector cable that is appropriatefor that phone. There are some considerations that you should keepin mind when selecting such a connector, which concern the fact thatthe test phone can communicate with the PC via two separateprotocols:■ DIAG, the diagnostic protocol, which CAIT uses tocommunicate with the test phone during any type of call■ DATA, the modem protocol, which other programs can use tooriginate calls by sending AT commands to the phoneMost phones on the commercial market today that are based on aQUALCOMM chipset support the DIAG protocol over the primaryUART (UART1) via a RS-232 DB-9 serial connection.With the MSM5500 and subsequent chipsets, the DIAG protocol canbe mapped to a USB connection, allowing simultaneous access toDATA and DIAG protocols. If you are using a test phone based onMSM5500 or greater that was not manufactured by QUALCOMM,please contact that phone’s manufacturer to find out if they haveimplemented support for DIAG over USB, and if so, how to obtainthe USB drivers they approve for use with their device.QUALCOMM does not distribute USB drivers for other handsetmanufacturers, even though they use a QUALCOMM chipset.Commercial phones based on earlier MSM chipsets (MSM3100through MSM5105) may include a USB data cable, but those phonesmay support only the DATA mode over USB, while DIAG moderemains on UART1. With these types of phones, it is possible toswitch the USB connection between DATA and DIAG modes, butdoing so does not provide simultaneous access to DATA and DIAG.QUALCOMM has teamed up with handset manufacturer KyoceraWireless Corporation to develop a Dual Port Adaptor for theirhandsets, which allows DATA and DIAG to be mapped to UART1and UART2, respectively. This special piece of hardware goesbetween the host PC running CAIT and the test phone, and allowsfor simultaneous DATA and DIAG mode access. For more

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, DAMST0053To connect the security key to the CAIT computer, attach it to theappropriate port on your computer. If you use the parallel or serialport model, you can then attach any other cable or hardware thatwas previously attached to the port to the pass-through connectoron the key.For the security key to run properly, you must install the WIBU-KEYdriver software along with the CAIT application software. To dothis, select the Install Security Key option from the CAIT CD’sautorun menu.Licensed CAIT users who have issues with broken or lostcopy-protection devices should contact QUALCOMM TechnicalSupport as specified in “Technical support” on page xiv.A “Network Server” feature is also supported by the WIBU-KEYdriver software. This feature allows multi-license “network” keys tobroadcast available CAIT licenses across a LAN. Single license keyswill not function across a network in this way. If you wish toupgrade your single license key to a network key supporting one ormore licenses, please contact your QCTest Account Manager, orsend email to qctest-info@qualcomm.com. You will need to have anew key issued to you, as the part number of the key is different forlogistical and tracking purposes.

  28. 28. QUALCOMM Proprietary QCTest CAIT 3.1 User’s Guide 15SignalAnalysis2 Signal AnalysisOverviewCAIT contains several different windows that provide graphicdisplays of mobile phone signals. The Temporal Analyzer windowtracks the strength and arrival times of the multipaths of thosesignals from sectors in the phone’s Active (and, optionally,Neighbor) set. CAIT also supports QUALCOMM’s Retriever™ pilotscanner phone when CAIT is in Retriever mode (see “Configuring aRetriever phone” on page 209). The Signal Graphs window displaysvarious characteristics of the transmit and receive signals from themobile phone. The PN Grid and PN Graph windows display signalactivity at every PN offset or in a regular sampling of PN offsetswhen used with the Retriever pilot scanner.Temporal Analyzer windowThe Temporal Analyzer window displays graphs or line plots ofactive 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 thefollowing:■ View signal levels above or below the noise floor■ Increase or decrease the grid scale of the time offset or horizontalaxis of the display■ Increase or decrease the limit for the transmit (Tx) power control■ Configure the Temporal Analyzer display

  31. 31. 18 Chapter 2: Signal Analysis QUALCOMM ProprietaryViewing displaysThe Temporal Analyzer window shows multiple traces in differentcolors (when the colors are set up on the Configure Cells dialogbox—see “Configuring cells” on page 206). Each trace represents thesweep signal of a mobile phone searcher. The window displays agrid with horizontal and vertical axes that are divided into twodifferent scales.When the signal traces on the window stabilize and average, you candetermine the timing and power of the signals by using the X- andY-axis scales of the display.The horizontal or X-axis represents the time offset with a scale inpseudo noise (PN) chips. The vertical or Y-axis represents the signalpower level or strength with a scale in decibels (dB) for the energyper chip over the interference noise (Ec/I0). The horizontal scaleranges from ±12 to ±96 chips, and the vertical scale ranges from 0 to−40 dB.Special indicator symbols are displayed to represent the signalpeaks for up to twelve fingers (demodulators). The number of thefinger is listed inside a diamond at the top of the indicator.

The noise flooris the upper boundary or average limit of the ambient noise (I0)density.The Temporal Analyzer uses the configurable noise threshold tolimit display of Ec/I0 below the threshold value—that is, valuesunder the noise threshold are “clipped” to the noise threshold. TheToggle Display under Noise Floor menu option toggles the range ofthe display of the Temporal Analyzer. When the option is enabled(checked), the display expands as the user changes the threshold sothat the corresponding value of Ec/I0 is always at the bottom of thegraph. When the option is disabled (unchecked), the bottom of thegraph corresponds to the value -40 dB Ec/I0, independent of thenoise threshold setting.To toggle the Temporal Analyzer display, do the following:1. In the View menu, click Temporal Analyzer or press F2 to openthe Temporal Analyzer window with all plot lines above thenoise floor.
