Outline
The DEXIN NDS3402A DVB-S2 modulator is a high performance modulator developed according to DVB-S2 (EN302307) standard which is the standard of second generation of the European broadband satellite telecommunication. It adopts advanced framing structure, channel coding and modulation technology, increasing over 50% transmission ability more than DVB-S modulator under the same transmission condition and also providing a more powerful receiving ability in the same spectral efficiency. In addition, it is backwards-compatible with DVB-S (EN300421) modulating standard. This DVB-S2 modulator supports local and remote control through NMS software. The NDS3402A DVB-S2 modulator can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.
