(See Figure 4-8).
CDMA Analyzer Test This test sets up the Test Software to make several measurements manually. The following measurements may be performed: • Channel Power • Rho (modulation quality).
Performing Tests CDMA Analyzer Test Step 3. Follow the displayed instructions and diagram to select and make the measurement. NOTE This procedure might include steps that prompt you to disconnect cables from the site antenna ports and make connections to the Test Set. Before removing or re-installing the antenna cables, make certain that the transmitter has been turned off by the MSC (or by switch personnel if not using a modem).
TX Antenna Port Cable Calibration Test This utility measures the signal loss through the cable used to connect the Test Set to the Base Station TX Antenna Port. This loss must be known when making power measurements. Once this value is measured, you should label the cable indicating the loss through it for future use. This routine requires the use of two external 6 dB attenuators (pads) and a short calibration cable.
Performing Tests TX Test Port Cable Calibration Test TX Test Port Cable Calibration Test This utility measures the signal loss through the cable used to connect the Test Set to the Base Station TX Test Port. This is the Base Station port that samples the transmitter output of the BCR through a directional coupler. This loss must be known when making power measurements. Once this value is measured, you should label the cable indicating the loss through it for future use.
TX Test Port Calibration Test This utility measures the loss associated with testing from the Base Station TX Test Port. This provides to the Test Software a coupling factor to use with measurements from the TX Test Port. At the start of the test, the Test Software will prompt you to choose either full or specified calibration. • Full calibration will first measure the level at the Base Station TX Antenna Port, then measure the level at the Base Station TX Test Port.
Performing Tests TX Test Port Calibration Test Select and Run the Test Perform TX Test Port Calibration utility operations as follows: NOTE This procedure might include steps that prompt you to disconnect cables from the site antenna ports and make connections to the Test Set. Before removing or re-installing the antenna cables, make certain that the transmitter has been turned off by the MSC (or by switch personnel if not using a modem).
PN Offset Search Test This utility may be used when you are testing a BBA and are uncertain of the PN offset value. In this utility, the Test Software tunes to the CDMA channel and searches to find the valid PN offset. The resulting PN offset value is then entered into the PN Offset field of the Test Configuration Menu screen. Parameters and Specifications Used The following specifications and parameters are used when running this test.
Performing Tests Insertion Loss Measurement Insertion Loss Measurement This measurement determines the loss associated with RF cables, filters, and other passive devices in the measurement path. This test uses the Test Set internal source and measures the relative loss through the cable or device. To optimize measurement accuracy, the measurement setup diagram indicates the use of two external 6-dB attenuators (pads) and a short calibration cable. The pads are optional, but should be used if available.
Step 7. The Test Software will turn on the source and make a reference measurement, then prompt you to add in the cable or device to be tested. Leave the calibration cable and pads connected to the ANT IN port and insert the cable or device to be measured as shown in the diagram. Press the k1 (Proceed) key to make the insertion loss measurement. Review the Results When making a discrete measurement, the Test Software will display the insertion loss as a single numeric value (in units of dB).
Performing Tests Return Loss Measurement Return Loss Measurement This measurement is used to determine the return loss of a cable, antenna, or other device in the swept mode. An SWR bridge and a 6-dB pad are connected to the Test Set. The Test Software uses the pad to improve the mismatch between the SWR bridge and the ANT IN port on the Test Set. A reference level is measured with an open or short on the bridge and then the return loss is measured with the cable or antenna-under-test.
Step 5. Press the k1 (Run) key to start the test. NOTE This procedure might include steps that prompt you to disconnect cables from the site antenna ports and make connections to the Test Set. Before removing or re-installing the antenna cables, make certain that the transmitter has been turned off by the MSC (or by switch personnel). The green ACT LEDs on the ADU and BCR modules indicate that the transmitter is active, and therefore should be off before disconnecting cables. Step 6.

Reference BTS Laptop Utility Program Windows 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.
Reference BTS Laptop Utility Program Windows Figure 5-16 Other Data Window Showing Short-Form Test Results Test Results Window NOTE Because short-form test results are not used in CDMA testing, the test results display in this window, which is ordinarily called “long-form test results” is called simply “test results” in the CDMA application described in this manual. The Test Results window displays test results. These results may be saved for later use (see Figure 5-17 for an example of the display).
Reference BTS Laptop Utility Program Windows Test Set Screen Capture Window The Test Set Screen Capture window allows you to capture a Test Software screen image and save it as a bit map file for later view or use. 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.
Reference 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.
Reference Demo (Demonstration) Mode Step 3. Select the Parm Test Parameters field. The Test Software will display the TESTS (Test Parameters) screen. Step 4. Select the Parm# field to allow scrolling. Step 5. Scroll to the ZZZZ Test Demo Mode field and press the knob again to stop the scrolling function. Step 6. Turn the knob clockwise to place the cursor to the left of the value field (0.000000) below the parameter name. Step 8. Press the k5 (Main Menu) key.
Reference Parameters Parameters The Test Software uses entries that you make in the Test Parameters screen to customize testing and configure the modem. A special parameter allows you to run the Test Software in a demo 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 108).

Reference Parameters 16. SP9 Parity [0=0 1=1 2=none 3=even 4=odd] This parameter specifies the kind of parity to be used for communication between the PC and the Test Set SERIAL 9 port. The setting must match the setting used by the PC communication program. Use the DATA ENTRY keys to enter a value. For more information on using this parameter, see “Configuring the Test Set and PC Serial Ports for Communication with the Test Set” on page 29. • Enter 0 for zeros parity. • Enter 1 for ones parity.
Reference Parameters 23. ZZZZ Test Demo Mode [0=normal 1=demo] This parameter specifies the Test Software operating mode. • Select 0 to cause the Test Software to operate in normal mode. • Select 1 to cause the Test Software to operate in demonstration (demo) mode. The demo mode will allow you to run the tests without really testing or connecting to a Base Station. This allows you to become familiar with Test Software operation. For details, see “Demo (Demonstration) Mode” on page 108. 24.
Reference 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, a “fail” indication is generated on the printout (and in some cases you are able to make adjustments and re-test). This section lists each pass/fail limit name and explains how it is used.
Reference Specifications (Pass/Fail Limits) 6. Output Power Adjustment Error These pass/fail limits determine the manner in which the power meter will be displayed. When the power meter display is shown, it will include 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. Units are dB. 7.
Reference Testing without MSC Control Testing without MSC Control Chapter 4, “Performing Tests,” on page 51, 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.
Reference 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 When a card is new, or the battery has been removed when the card is not inserted into the Test Set, then the card must be initialized to store data. To initialize a PC card follow these steps: Step 1.
Troubleshooting 6 Troubleshooting This chapter contains information that is useful if you encounter Test Software or measurement errors or if you question measurement results.
Troubleshooting Error Summary Error Summary Overview This chapter lists errors that might be encountered when loading or running the Test Software. The errors are listed roughly in the order of possible occurrence when getting started using the Test Software: “Troubleshooting the Test Software Installation” on page 121. “Errors When Loading and Running the Test Software” on page 122. “Errors When First Setting Up or Connecting to MSC” on page 123. “Communication Errors During Testing” on page 123.
Troubleshooting 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.
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.
Troubleshooting Communication Errors Communication Errors Errors When First Setting Up or Connecting to MSC • Message: Base Station did not answer command... 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 124 for a list of items to check when you have noticed this error.
Troubleshooting 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 “Accessory Kits” on page 17.
