Measuring Waveform Quality + Code Domain Power

Measuring Waveform Quality + Code Domain Power

Last updated: January 16, 2009

General Procedure

   
NOTE
Channel power calibration should be performed if the test set is being used for the first time or the operating environment has changed significantly since the last calibration was performed. The channel power calibration also calibrates the waveform quality + code domain measurement. See Calibrating the Test Set for details.

   

  1. Connect the access terminal to the test set's front panel RF IN/OUT connector and power it on.
  2. Wait for the access terminal to open a session and then open an RTAP (for subtype 0 physical layer), RETAP (for subtype 2 physical layer)or RMCTAP (for subtype 3 physical layer) data connection for AT's transmitter test. See How Do I Open a Session and Test Data Connection? for detailed procedure.

       
    NOTE
    When more than one test set is configured to perform a multiple carrier measurement (see Multi-carrier Multi-unit (MCMU) ), not all parameters can be set on each test set because of the interaction between the test sets. For example, some parameters can not be set or changed on the auxiliary unit because it is controlled by the main unit, and some of the parameters of the auxiliary unit can be set as associated parameters on the main unit. For which parameters can or can not be set on a single test set, see Multicarrier Parameters and Multi-carrier Multi-unit Setting Interactions .

       

  3. Set the RTAP Rate ( F12 ) or FTAP Rate ( F11 ) on the Call Parms 1 of 3 menu as needed if during an RTAP connection, or set the R-Data Pkt Size ( F12 ) or F-Traffic Format ( F11 ) on the Call Parms 1 of 3 menu as needed if during an RETAP connection.
  4. Initialize the waveform quality + code domain measurement:
    • Press the Measurement selection key.
    • Turn the knob to highlight the Waveform Quality + Code Domain measurement and press the knob.
  5. Select Waveform Quality + Code Domain Setup ( F1 ) to access the Waveform Quality + Code Domain Setup menu. From this menu you can configure measurement parameters such as Slots to Measure , DRC Channel Gain , etc. For statistical measurement results, highlight the Multi-Measurement Count parameter and press the ON key. The number of averages will default to 10.
  6. Select Close Menu ( F6 ) to close the Waveform Quality + Code Domain Setup window.
  7. If needed, set the RTAP Rate ( F12 ) or FTAP Rate ( F11 ) on the Call Parms 1 of 3 menu when during an RTAP connection test, or set the R-Data Pkt Size ( F12 ) or F-Traffic Format ( F11 ) on the Call Parms 1 of 3 menu when during an RETAP connection test.
  8. Measure waveform quality and code domain power:
    • If the Trigger Arm field is set to Single , press the START SINGLE key to trigger each measurement.
    • If the Trigger Arm field is set to Continuous , the measurement began executing as soon as you initialized it in step 3.
  9. Select Numeric Rho ( F2 ) to view the waveform quality results. A typical display is shown below.
  10. Select Code Domain Power ( F3 ) to view the code domain results. A typical display is shown below. When viewing the code domain results, you can select Marker Position ( F6 ) and turn the knob to select a Walsh code and display its power.

  11. Select Code Domain Power + Noise ( F4 ) to view the code domain + noise results. A typical display is shown below. When viewing the code domain + noise results, you can select Marker Position ( F6 ) and turn the knob to select a Walsh code and display its power.

Testing 4.2.2 Waveform Quality and Frequency Accuracy

For details on performing the steps below, see the General Procedure above.

  1. For Subtype 0 or 1 Physical Layer, set up a Test Application session and open an RTAP connection with the RTAP Rate set to 9.6 kbps . For detailed procedure on how to open an RTAP session and connection, see How Do I Open a Session and Test Data Connection? .

    For Subtype 2 Physical Layer, set up a Test Application session and open an RETAP connection with the following setups. For detailed procedure on how to open an RETAP session and connection, see How Do I Open a Session and Test Data Connection? .

    • Set the R-Data Pkt Size ( F12 on Call Parms 1 of 3 ) to 256 bits.
    • Set the Reverse Data Transmission Mode under the Application Config ( F10 on Call Parms 1 of 3 ) menu to High Capacity .
    • From the Power Parameters Info menu (see How Do I Change Channel Gain/Traffic Info Parameters? for how to access), set the 256-bit High Capacity Termination Target to 3 (4 sub-frames, 16 slots). (NOTE: You do not need to set these settings unless the default value (3) of these settings are changed. Changing these setting results in an open data connection closed because these settings are configured during session negotiation. Once this happen, you need to re-open the connection.)

  2. C.S0033 specifies to configure the FTAP or FETAP such that the ACK Channel is transmitted at all the slots. To do this, set the ACK Channel Bit Fixed Mode (Fwd TAP) to On from Application Config ( F10 under Call Parms 1 of 3 ).
  3. Initialize the waveform quality + code domain measurement. Set Slots to Measure to 1. See Recommended Slots to Measure Settings for details.
  4. Set Î or ( Cell Power ) to - 75 dBm/1.23 MHz .
  5. Measure waveform quality + code domain.
  6. For Subtype 3 Physical Layer, configure the AT to transmit on two carriers at the closest possible frequency separation between them and with the following setups.
  7. C.S0033 specifies to configure the Test Application FMCTAP (for Subtype3 Physical Layer) with the ACK Channel is transmitted at all the slots.
    To do this, set ACK Channel Bit Fixed Mode to On from Application Config ( F10 on Call Parms 1 of 3 ).
  8. Repeat 4-5.
  9. Select Numeric Rho ( F2 ) to view the Rho , Frequency Error and Time Error results. A typical measurement result is shown below.

For detailed procedure on how to open an RETAP session and connection, see How Do I Open a Session and Test Data Connection? .

Changing these setting results in an open data connection closed because these settings are configured during session negotiation. Once this happen, you need to re-open the connection.)

(NOTE: You do not need to set these settings unless the default value (3) of these settings are changed. Changing these setting results in an open data connection closed because these settings are configured during session negotiation. Once this happen, you need to re-open the connection.)

(NOTE: You do not need to set this parameter unless its default value (3) is changed. Changing the setting results in an open data connection closed and a session re-negotiation. Once this happen, you need to re-open the connection.)

(In order for the R-Aux Pilot Channel to be active for the test, the Auxiliary Pilot Channel Min Payload accessed from the Enhanced Traffic Parameters menu (see How Do I Change Channel Gain/Traffic Info Parameters? for how to access) must be set to a value no greater than the current R-Data payload size. NOTE: You do not need to set this parameter unless its default value (3072 bits) is changed. Changing the setting results in an open data connection closed and a session re-negotiation. Once this happen, you need to re-open the connection.)
