DVB -S2 modulator

DVB -S2 modulator

DVB -S2 modulator

1. QPSK/8PSK modulator
2. 10MHz outer reference clock input support
3. MER > 36
4. Support BISS

Outline

DVB-S2 modulator (with BISS) 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 standards. This DVB-S2 modulator supports local and remote control through NMS software. The NDS3402 DVB-S2 modulator (with BISS) can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.

 

Features

  •   Fully complying with DVB-S2(EN302307) standard
  •   Backwards-compatible with DVB-S (EN300421) modulating standard
