Datasheet

New features have been added to IZT’s S1000 signal generator family as the company expands its comprehensive support for Digital Audio Broadcast (DAB) applications. A DAB ContentServer Embedded Edition option integrates DAB, DAB+ and DMB multiplexing and makes the functionality of the DAB ContentServer directly available on the S1000 signal generator. This makes it easier to generate DAB test sequences and to test DAB receivers in real-time with the S1000.

The new software option allows users to encode and multiplex audio and data services for DAB, DAB+ and DMB. Its web interface provides flexible and comfortable access to the needed parameters. The Embedded Edition of the DAB ContentServer includes basic functionality of the DAB standards family, while an upgrade to the full DAB ContentServer Developer Edition is possible.

Furthermore, a real-time DAB/DAB+/DMB modulator is available for the S1000. The new modulator supports simultaneous streaming of multiple ensembles, allowing for a direct link between the DAB ContentServer and the S1000 with the EDI protocol. DAB ETI files can be used as an input source without conversion, which enhances usability and saves conversion time.

The real-time DAB modulator is capable of dynamic reconfigurations, which is essential to support the full test range of the DAB standard. The powerful impairment features of the S1000 (including multipath fading and time variant profiles) can be applied to the real-time DAB modulator.

To underline its strong commitment to digital radio, IZT joined WorldDMB, the global forum that is facilitating the adoption and implementation of digital radio based on DAB, DAB+ and DMB.

WorldDMB works with broadcasters, network providers, car, receiver, chip and equipment manufacturers, governments and official bodies to encourage international co-operation and a smooth, coordinated roll-out of services.
