Leader LT448

Model Details

The LT 448 Multiformat Pattern Generator is designed to output analog component and composite signals applicable to the DTV systems. There is also a DVI-D output connector. This innovative generator includes a total of 29 digital television video signal formats conforming to Advanced Television Systems Committee (ATSC), and Digital Video Broadcast (DVB) Integrated Services Digital Broadcasting (ISDB), standards throughout the world. Component analog signals are output for 17 formats of DTV conforming to ISDB,ATSC, and DVB standards based on 1920 x 1080, 1280 x 720, 720 x 480, and 720 x 576 raster formats. The NTSC/PAL/SECAM composite output and VGA, used for a computer monitor, are provided. These 29 formats are suitable for production line applications of projectors, etc. Computer D-15 outputs are available in VGA, SVGA, XGA and SXGA. The test patterns, generated in the digital domain, include five types of color bars, raster, ramp, 10/15/32/64 stair steps, convergence, crosshatch, multiburst, character, small and normal windows, demodulation, monoscope,ANSI gray scale, checker and optional natural picture. Natural picture allows user to download custom bit maps into internal RAM.
