Rohde & Schwarz CCVS + Component Generator SFF

The Rohde & Schwarz CCVS + Component Generator SFF is a Small Form Factor signal generator engineered for precision video signal generation and analysis in broadcast and consumer electronics testing. The unit produces composite color video signals (CCVS), YCBCR, RGB, and S-VHS formats across multiple television standards including B/G/PAL, M/NTSC, M/PAL, and N/PAL (625-line and 525-line variants). It generates all standard test signals per CCIR Rec. 801, including pathological patterns, shallow ramps with 10-bit resolution, and specialized signals such as Splitlevel, Coring, sinx/x, and Bowtie.
