It outputs 4K UHD and Full HD signals simultaneously across HDMI 2.0, dual 3G-SDI, and optical fiber (SFP) interfaces, covering the full range of formats in use across modern broadcast and production facilities.\u003c\/p\u003e\u003cp\u003eThe unit features a 4.3-inch color display for at-a-glance status monitoring and front-panel controls for direct access to pattern selection, timing, audio, and system settings without requiring a PC. Signal formats span HDMI 2.0 resolutions up to 3840x2160 (4K UHD) and 4096x2160 (DCI-4K) at refresh rates through 240Hz, as well as HD-SDI and 3G-SDI Level A and Level B-DL\/B-DS up to 2048x1080. A rich set of test patterns includes SMPTE color bars, grey bars, ramp, window, EQ\/PLL test, and user-importable custom images.\u003c\/p\u003e\u003cp\u003eEmbedded audio is handled independently for each output path, supporting up to 16 channels of AES\/EBU audio per SDI channel and up to 8 channels on HDMI, with adjustable level (-60dB to 0dB), frequency (20-20000Hz), and phase (0, 90, 180, 270 degrees). Auxiliary functions include LTC\/VITC timecode insertion, image overlay (frame count, circle, border, center cross), and a scrollable image traverse function with configurable step size. The robust metal chassis accepts DC 12V or USB Type-C (5V) power for flexible use in rack rooms and field deployments alike.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Format 4K and HD Outputs:\u003c\/strong\u003e Simultaneous HDMI 2.0 (up to 4K UHD \/ DCI-4K), dual 3G-SDI (up to 2048x1080, Level A and Level B), and SFP optical fiber output from a single compact unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Test Pattern Library:\u003c\/strong\u003e Generates SMPTE 100%\/75% color bars, grey bars, ramp, window, EQ Test\/PLL test, and custom user-imported images for thorough display and link verification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e16-Channel Embedded Audio with Full Control:\u003c\/strong\u003e Supports up to 16 AES\/EBU audio channels per SDI output and 8 channels on HDMI; adjustable level, frequency, and phase offset for complete audio path testing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Overlay and Timecode Functions:\u003c\/strong\u003e Inserts LTC and VITC timecode; overlays frame counters, border lines, and crosshair markers; supports 4-direction image scroll with adjustable step size for precision alignment checks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4.3-Inch Display with FPGA-Powered Control:\u003c\/strong\u003e Built-in color screen and front-panel buttons provide direct access to all settings; FPGA-based processing ensures stable, long-term performance suited to demanding production and broadcast environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVideo Outputs:\u003c\/strong\u003e 3G-SDI x2 (BNC), SFP Optical Fiber x1, HDMI 2.0 x1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHDMI 2.0 Resolutions (VESA):\u003c\/strong\u003e 1024x768, 1280x1024, 1920x1080, 2560x1440 (QHD), 3840x2160 (4K UHD) at 60\/75\/120\/144\/165\/240Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHDMI 2.0 Resolutions (CEA-861):\u003c\/strong\u003e 480p, 720p, 1080i\/p, 2160p (4K UHD), 4096x2160 (DCI-4K) at 24\/25\/30\/50\/60\/120Hz; sampling RGB \/ YCbCr 4:4:4 \/ 4:2:2 \/ 4:2:0, 8-10bit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3G-SDI Formats:\u003c\/strong\u003e SD-SDI (525\/625), HD-SDI (720p, 1080i\/p), 3G-SDI Level A and Level B-DL\/B-DS up to 2048x1080; YCbCr 4:2:2 10bit, GBR\/GBRA 4:4:4 10-12bit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest Patterns:\u003c\/strong\u003e Color Bar 100%\/75%\/SMPTEEG1-1990, Grey Bars, EQ Test\/PLL Test, Ramp, Window, Custom Value, Picture (user import)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmbedded Audio:\u003c\/strong\u003e Up to 16-channel SDI AES\/EBU and 8-channel HDMI; level -60dB to 0dB; frequency 20-20000Hz; phase offset 0\/90\/180\/270 degrees; 3.5mm stereo audio output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTimecode and Overlay:\u003c\/strong\u003e LTC \/ VITC timecode; graphic overlay (frame count, circle, border, center cross); 4-direction image traverse with configurable step size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e 4.3-inch built-in color screen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e DC 12V or 5V via USB Type-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H):\u003c\/strong\u003e 135.2 x 117.2 x 35.6mm (5.3 x 4.6 x 1.4 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Weight:\u003c\/strong\u003e 310g (0.68 lbs); shipping weight listed separately in assumptions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e 0 degrees C to 50 degrees C; Storage: -30 degrees C to 70 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis:\u003c\/strong\u003e Robust metal construction for durability and heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sprolink","offers":[{"title":"Default Title","offer_id":46267766931653,"sku":"SPRO-SGUHD","price":1399.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/sprolink-sg-uhd.jpg?v=1779482212","url":"https:\/\/avlgear.com\/products\/sprolink-sg-uhd-4k-uhd-signal-generator-with-hdmi-2-0-3g-sdi-and-fiber","provider":"AVLGEAR","version":"1.0","type":"link"}
