The Lilliput SG-12G is a test pattern generator for checking video displays and SDI equipment, supporting signals up to 4K at 60 Hz. Its 7-inch IPS screen provides a clear interface for selecting built-in patterns, importing custom images and creating RGB or YCbCr colour patterns to assess colour temperature and greyscale performance.

With 12G-SDI and 3G-SDI outputs, single, dual and quad-link support, and optional fibre output, it accommodates a wide range of video setups. Adjustable embedded audio, reference synchronisation, timecode and text or frame-counter overlays provide additional testing tools, while a built-in battery and metal housing make it practical for portable use.
