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.
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.
