DTA-2139B - Twelve-Channel Cable/Terrestrial Receiver for PCIe  


Twelve-Channel Cable/Terrestrial Receiver for PCIe

Twelve (!) receivers on a single card, supporting any mix of cable (DVB-C, QAM-B/C) and terrestrial (DVB-T, DVB-T2, even ISDB-T) signals. All twelve transport streams are demodulated simultaneously, allowing you to monitor a complete network in real time.

The DTA-2139B is an obsolete product that is no longer in production.

For new designs, DekTec recommends the DTA-2139C, which supports new standards including ATSC 1.0 and ATSC 3.0.

  • Next generation of the DTA-2139 with improved RF quality and support for terrestrial standards DVB-T, DVB-T2 and ISDB-T.
  • Twelve independently-tunable tuners and twelve demodulators, each outputting the full transport stream.
  • Each receiver provides an indication of lock status, RF level and MER for that channel.


  • 24/7 continuous compliancy monitoring of an entire cable or terrestrial network.
  • Receiving all (or many) services in a free-to-air terrestrial network and remultiplexing them to a cable network.
  • Creating a mosaic of all services on a cable or terrestrial network.

Block Diagram

The RF input signal is amplified and split, feeding twelve receiver sections. Each receiver channel consists of a chip tuner, chip demodulator and an optimized DMA controller.

Block diagram of the DTA-2139B

The loop-through connector found on the DTA-2139 has been dropped, giving the DTA-2139B a slightly higher performance.
