Features

Supports all constellations and modulation modes for each supported standard.
Excellent signal quality through direct digital synthesis of the RF output signal.
No power supply required: A single USB-3 connection supplies power, real-time data and control.

Standards included with base product:
ATSC 8VSB,
DVB-C,
DVBS/S2,
DVB-T, DVB-T2 single PLP
QAM-B, QAM-C

Options:
ATSC-M/H
ATSC 3.0 (in development)
CMMB
DAB(+), T-DMB
DTMB (ADTB-T, DMB-T/H)
DVB-C2
DVB-S2X
DVB-T2 multi PLP
ISDB-S, ISDB-T, ISDB-Tmm

Applications

General-purpose test modulator in your R&D lab for developing, qualifying or repairing any equipment with an antenna input.
Portable demo set for TV receivers, easy to carry to customer demos, trade shows, etc.
TV distribution using modulated signals in shops, hotels, hospitals etc.

Block Diagram

The DTU-315 reads data from USB and forwards it to a baseband modulator, a channel filter, an optional channel simulator and an upconverter. The digital RF signal is converted to analog with a high-speed D-to-A converter and output on a micro-BNC connector.
