DVB-S/S2 Satellite Modulator

SMD 989

The SENCORE SMD 989 professional satellite modulator is ideal for MPEG Transport Stream transmission using DVB-S/S2/S2X or Broadcom TurboPSK modulation. Leveraging the latest modulation technology, the SMD provides high-value solution with unmatched signal quality.

Support for DVB-S2X and Multistream with Variable Coding and Modulation (VCM) ensures the SMD will be ready for the future of S2 modulation. Integrated processing features such as TR 101 290 error checking and BISS scrambling make the SMD an ideal solution for video delivery.

The optional, built-in L-Band upconverter enables the SMD 989 to provide an IF or L-band output. This eliminates the need for multiple pieces of equipment and provides a compact solution for facilities housing multiple modulators or for insertion into L-band inter-facility links.

The chassis has two bays allowing for a variety of configurations, including two independent modulators for density, redundant power supplies for reliability, or DC BUC power for truck installs.

  • Super-efficient S2X modulation schemes and roll off factors
  • Broadcom TurboPSK modulation modes
  • Ability to modulate 1 to 6 multistream transport streams on a single carrier (single-box multistream solution)
  • L-band and IF outputs
  • Optional diplexed 10MHz and DC power on L-band
  • Front panel and web GUI for easy configuration
  • ASI and IP inputs
  • Available with dual, redundant power supply
