Sprolink SG-UHD 4K Multi-Format Signal Generator
The SG-UHD is a dedicated pattern generator for verifying 4K HDMI and 3G-SDI signal chains before a system goes live, built on an FPGA architecture rather than a software test app. It outputs test patterns across both HDMI and SDI simultaneously, with an SFP cage for fiber links and embedded audio for testing signal chains end to end.
It covers the job an integrator otherwise does with a laptop and a test-pattern file: confirming that a display, extender, or matrix input is actually receiving and locking to a clean 4K signal at the resolution and format the install calls for, on both copper and fiber runs.
