New and Used VSAT Satellite Modulators





Sola-Sat MS2-LB DBV-S2 Modulator (with BISS)

Outline

The Sola-Sat MS2-LB 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 Sola-Sat MS2-LB DVB-S2 modulator (with BISS) can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.

Features

  1. Fully compliant with DVB-S2(EN302307) standard
  2. Backwards-compatible with DVB-S (EN300421) modulating standard
  3. Two ASI inputs supporting hot backup
  4. BISS scrambling mode; mode0, mode1 and mode E optional
  5. Supporting local and remote control
  6. Output level attenuation
  7. 10MHz outer reference clock input
  8. Output frequency range: 950~2150MHz
  9. Full-size front panel LCD display and keyboard
