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.
Key Features of the DTU-315 Explained
The presentation below explains key features and benefits of the DTU-315.
DTU-315 in Action
A tablet drives the DTU-315. The RF output signal is shown on a spectrum analyzer.
A rackmount kit (DTR-315-RACK) is available to install up to eight DTU-315 units in a 19" rack.
DTA-2115B – All-standard VHF/UHF/L-band modulator for PCIe
DekTec's highest-end modulator. The DTA-2115B and DTU-315 share the same set of modulation standards, the same frequency range and an all-digital modulation and upconversion architecture.
Differences: The DTA-2115B has a higher output level (0dBm vs. -25dBm) and a better phase noise figure. The DTU-315, being USB based, can be used with laptops and is easier to install for desktops and servers.
DTU-215 – Cable/terrestrial modulator for USB-2
A lower-cost portable modulator if you need cable and/or terrestrial modulation, but not satellite standards in the L-band (supported by the DTU-315). The DTU-215 will not support ATSC 3.0 either.
Apart from an attractive price point, another advantage of the DTU-215 is that it can operate from a USB-2 port. The DTU-315 requires a USB-3 port.
