Features

Next generation of the DTA-2139B with added support for ATSC 3.0 and ATSC 1.0 (8VSB). Combinations are supported, too!
Twelve tuners and demodulators, each tunable to any frequency in the VHF or UHF band, and each outputting the entire 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.
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.
