How to Perform DPD Evaluation Using Custom Modulation Signals in RFIC Test Software

Issue Details

Is it possible to perform Digital Pre-Distortion (DPD) evaluation using original or custom modulation signals in RFIC Test Software? If yes, what are the steps and are there any additional requirements or licenses?

Solution

Yes, RFIC Test Software supports DPD evaluation using custom modulation signals. This can be achieved through the RFIC Soft Front Panel by following these steps:

Steps to Perform DPD Evaluation with Custom Signals

1. Launch RFIC Soft Front Panel.
2. Navigate to the Waveform tab.
3. Set RF Standard to Custom. This allows you to configure ACP (Adjacent Channel Power) for a custom waveform file in TDMS format.
4. Load your custom TDMS waveform file.
5. Configure ACP settings as needed:
   1. When RF Standard = Custom, ACP parameters can be fully customized.
   2. When using predefined standards (e.g., LTE), ACP values are fixed according to the standard.
       
6. Proceed with DPD evaluation using the loaded custom waveform.

Additional Information

License: An RFIC Test Software license is required to use the RFIC Soft Front Panel and perform DPD evaluation.

Waveform File: Ensure your custom waveform is in TDMS format.
