      產品詳細介紹Product Introduction

      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.

       

      Features

      • 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.


      Applications

      • 24/7 continuous compliancy monitoring of an entire cable or terrestrial network, using Xpect Mosaic or another monitoring solution.
      • 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.

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