A DAB/DAB+/DMB flexible generator is essential in factory testing facilities to verify the correctness and performances of the radio receivers manufacturing, design validation and quality insurance.
WisyDAB provides user-friendly LabVIEW® API’s for creation of DAB/DAB+/DMB signals from an Ensemble Transportation Interface (ETI) file. The input ETI file and the signal duration are user selectable.
Each selected ETI file is decoded in order to immediately preview the associated Ensemble information such as the Ensemble Name, the Service Name, the Service Bit Rate, and the Service protection level.
This feature allows the user to verify selected ETI input file integrity.
WisyDAB is a valuable tool for R&D validation tests.
Automation of manufacturing tests may be developed through the provided NI LabVIEW® API.
The Signal waveforms can be stored and played at RF frequency according to the signal format created by the user within the modulation framework (e.g., single shot play, looping).
The package includes a set of NI LabVIEW® VIs with source examples of common radio applications.
This set allows the user to easily integrate WisyDAB functionalities into NI LabVIEW® applications.
