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.
