The Rohde & Schwarz CCVS + Component Generator SAF is a multi-standard video signal generator engineered for broadcast television, component testing, and R&D verification. It generates CCVS, YCBCR, RGB, and S-VHS signals across B/G PAL, M/NTSC, M/PAL, and N/PAL standards with selectable 4:3 or 16:9 aspect ratios. The instrument delivers real-time signal generation using a high-speed RISC Transputer processor and LSI gate arrays, producing 10-bit resolution shallow ramps and comprehensive test patterns.
