L-band DVB-S-S2-T modulator board can be used in various converters, modulators, transmodulators and other digital broadcasting equipment.

The sources of input transport stream for this modulator board may be the followings:


  • High quality of the modulated signal;
  • Remote management, monitoring and configuration by IP (using our IP control board)
  • High symbol rate;
  • Modulation up to 32APSK;
  • Small size and low power consumption;
  • Flexibility of scheme and devices which include our DVB boards.
