DekTec DVB-S Modulator Card


The DTA-107 is a PC-based solution for a complete DVB-S modulator with L-Band up-converter from 950-2150 MHz that allows for direct RF connection to a satellite receiver.

Sencore is the preferred distributor of DekTec in North America.

  • DVB-S modulator compliant to ETS 300 421
  • Integrated L-Band upconverter with on board 950 to 2150MHz synthesizer
  • Wide range of symbol rates allows for both MCPC and SCPC operation
  • RF output can be connected directly to digital satellite receiver
  • Complete on board channel coder with Reed-Solomon encoder, convolutional interleaver and base band shaping filter
  • Programmable convolutional rate: 1/2, 2/3, 3/4, 4/5, 5/6, 6/7 or 7/8
  • Software interface compatible with other DekTec digital video output adapters
  • PCI rev 2.2, 32 bit, 33 or 66 MHz bus
  • Comes with free:
    • Windows & Linux device driver and software Development Kit for developing custom applications
    • Example source code for stream player
    • DtLoop application to copy packets from an input adapter to the DTA-107
  • With the StreamXpress (DTC-300) software as a standalone disk player that generates a DVB-S modulated signal for typically one or more digital satellite receivers
  • With DtLoop as a modulator replacement. An input adapter (e.g. the DTA-120 DVB-ASI Input PCI card) is used to read a transport stream input, and DtLoop copies the stream real-time to the DTA-107
  • As DVB-S output adapter in your (OEM) application
