SG-UHD

The Sprolink SG-UHD is a 4K UHD test pattern and video signal generator designed for professional AV and broadcast applications, featuring HDMI and optical fiber outputs (via an optional SFP module). It replaces the SG-HD, offering extended UHD capabilities while remaining highly versatile for video testing and validation workflows.

The unit also includes dual 3G-SDI Full HD outputs, enabling reliable testing and verification of SDI display chains and signal paths. Its built-in 4.3-inch screen provides quick access to a wide range of professional test patterns, including color bars, vertical/horizontal patterns, grids, square patterns, and other reference signals suitable for calibration, quality control, and troubleshooting in the field.

The SG-UHD supports SD/HD/3G-SDI Level A, 3G-SDI Level B (DL/DS), as well as 4K HDMI, 60p SDI, and fiber transmission. Key signal parameters can be adjusted with precision, including resolution, frame rate, sampling structure, and color space. Users can also import custom test graphics to match specific workflows or client requirements.

On the audio side, the SG-UHD supports up to 16 channels of AES/EBU audio, with channel selection, gain adjustment, and control over phase and frequency. Through the dedicated “Options” button, the unit provides additional advanced features such as Time Code generation (LTC / VITC), on-screen overlay, and an image motion mode with configurable movement across four axes, useful for evaluating motion processing and display performance.

Compact, rugged, and cost-effective, the SG-UHD delivers a reliable and complete solution for broadcast engineers, integrators, and technical teams, ensuring fast and accurate testing across SDI, HDMI, and fiber-based video systems.
