Features
- Supports all constellations and modulation modes for each supported standard in VHF, UHF and L-band.
- Excellent signal quality through direct digital synthesis of the RF output signal and an on-board ultra-low phase noise oscillator.
- Can be used for wide-band advanced modulation schemes, such as 16-MHz multi-segment ISDB-Tmm, DVB-S2X and 64-MHz DVB-C2 channel bonding.
Applications
- High-end general-purpose test modulator in your R&D lab for developing and qualifying DTV equipment, or for experimentation with new RF modulation schemes.
- Automatic test equipment (ATE) for tuners, demodulator chips, receivers, TV sets etc.
- Play-back of arbitrary I/Q sample files that are recorded or pre-computed (e.g. with MATLAB), with a bandwidth up to 72-MHz.
Block Diagram
The DTA-2115 reads data from the PCI Express bus 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 main and monitor output.

DTA-2107 – Multi-Standard Satellite Modulator for PCIe PCI Express modulator with L-band output for satellite standards DVB-S, DVB-S2 and ISDB-S. For DVB-S2X the DTA-2115 or DTU-315 is required. The DTA-2107 is a low-profile card, while the DTA-2115 is standard-profile PCIe card. If you only need satellite modulation and no DVB-S2X, then the DTA-2107 is a cost-effective alternative to the all-standard DTA-2115. |

DTA-2111 – Multi-Standard Cable/Terrestrial Modulator for PCIe PCI Express modulator with VHF/UHF output for cable and terrestrial standards. The DTA-2111 does not support satellite standards, nor will it support ATSC 3.0. The DTA-2111 is a low-profile card, while the DTA-2115 is standard-profile PCIe card. Compared to the DTA-2115, the price point of the DTA-2111 is very attractive, making it an excellent choice for OEM applications. |

DTU-315 – All-Standard 0-2GHz Modulator for USB-3 A portable variant of the DTA-2115: Easy to install and easy to carry to demos and around the lab. Like the DTA-2115, the DTU-315 uses an all-digital modulation and upconversion architecture. However, as the DTU-315 is bus powered, the DTA-2115 has the best specifications for output level (0dBm vs -25dBm) and phase noise. |
