VCO-DVB-S2 modulator with BISS

The VCO-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 standard.

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