Configuring DAB Signals for Receiver Test

The following example procedure shows you how to configure the equipment and Signal Studio software for a DAB signal receiver test.

In parameter view windows, you can check and then click the desired parameter for a brief description.

  1. Set up the equipment as shown below.   

  2. Select the DAB standard.

    Open the software and select DAB in the Format, shown as follows.

  3. Configure Carrier 0.

    Click Carrier 0 from the tree view and set the parameters on the carrier setup window as needed. Here, use the default settings.

    By clicking , you can add more carriers to the DAB signals under test. Signals on each carrier can be configured independently. For example, one carrier can send DAB signal and another one can send DAB+ signal. For more details, refer to Carrier Configuration Summary Table.    

  4. Configure the Ensemble.

    Select Ensemble from the tree view. There are two methods to configure the ensemble.

    1. Select ETI (G.703) or ETI Demo (G.703) as the Input Pattern, and use an ETI file as payload. Using this method, the parameters for services and service components will be set automatically. Then you can skip step 5, step 6 and go to step 7 directly.

    2. Select By Each Service Component as the Input Pattern, then configure each service and service component.  

  5. Configure the Service Component 0.

    Select Service Component from the tree view, and then click on Service Component 0.

  6. Configure the Service 0.

    Select "10.Pop Music / Country" as the Programme Type.

  7. Configure the signal generator settings.

    Click the Signal Generator in the tree view and set the frequency and amplitude to the values below.

  8. Generate and download the waveform to the signal generator.

  9. Evaluate the DAB messages on the receiver.
