Creating a 1xEV-DO Rev. A Reverse Configuration

This procedure shows you how to configure a multicarrier reverse link signal. This procedure assumes that you have successfully completed the required installation and equipment setup.

  1. Click Waveform Setup in the tree view. In the parameter view, click to add a new waveform.

  2. Enter the name, "DO-A RL" in the Waveform Name cell, and "Example" in the Comment cell. Leave Playback and Mode parameters off.

  3. Click WFM1 in the tree view.

  4. In the parameter view, click and select Basic 1xEV-DO Rev.A Reverse. Notice that a new Carrier node with a Channel Setup node has been added to the tree view.

  5. Click Carrier 1 in the tree view and accept the default parameter settings displayed in the parameter view.

  6. Click Channel Setup in the tree view.

    1. Set the Auxiliary Pilot Channel State to Off.

    2. For RRI Relative Channel Gain, enter the value –6.00 dB.

    3. For DSC Channel Relative Gain, enter the value –12.00 dB.

    4. Leave the default values for the RRI State, DRC State, and all other parameter settings.

  7. Click Packets in the tree view.

    Click each Physical Layer Packet 1-3 Data Rate cell, and select 38.4 / 19.2 / 12.8 / 9.6 kbps (256) B4 from the drop-down window. The values correspond to the data rate [kbps] after 4, 8, 12, and 16 slots, (payload data size [bits]), and modulation type respectively.

  8. Click Timeslots in the tree view.

    1. For DSC Data, enter 1.

    2. For the RRI Payload Index, enter 0. 

    3. Leave all other parameters settings at their default values.

  9. To add additional carriers, repeat steps 3 through 8, configuring the Carrier, Channel, and Timeslots as desired.

  10. Click in the tool bar. The software generates an I/Q waveform file in accordance with the current channel configuration and signal generation setup. Waveform generation time varies proportionally with the complexity of the waveform.

  11. After the waveform is generated, you can examine its characteristics. You can view plots of the baseband spectrum, I and Q signals, and CCDF curve prior to downloading the file to the signal generator.

    1. In the tree view, click WFM1.

    2. Click the CCDF and Waveform tabs at the bottom of the window to view their respective graphs.
