DTA-2139B

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.

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.
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.

	DTA-2139C – Twelve-Channel Cable/Terrestrial Receiver for PCIe Next generation of DTA-2139B with ATSC 3.0 and ATSC 1.0 added.
	DTA-2138B – Single-Channel Cable/Terrestrial Receiver for PCIe Single-channel hardware-based receiver that uses the same tuner and demodulator chip as the DTA-2139B.
	DTA-2131 – Multi-Standard Cable/Terrestrial Receiver for PCIe Single-channel software-based receiver. Compared to the DTA-2139B, SDR technology allows the DTA-2131 to perform advanced RF measurements and support more modulation standards like ATSC 3.0.
	DTA-2115B – All-Standard VHF/UHF/L-Band Modulator for PCIe The "other side": DekTec's high-end modulator. With 8-channel firmware option, the DTA-2115B can modulate eight 8-MHz signals, which can all be demodulated by a single DTA-2139B, with 4 channels spare.
