Rohde & Schwarz SFF
NTSC & PAL Video Generator Composite Outputs
Description
This Video Generator Composite Output is suitable for all applications in the field of television.
This unit supplies all test signals and patterns required for video measurements in CCVS, YCBCR, RGB and S VHS formats, for test patterns an aspect ratio of 4:3 or 16:9 being selectable.
SAF and SFF also generate all test signals to CCIR Rec. 801, a number of common pathological test signals, and shallow ramps with a resolution of 10 bits.
Such amplitude and phase adjustments of signal components enable testing of gain controls, white level limiting circuits and video analyzers over the whole range of the devices.
User specific signals can be defined by front panel entry and stored in the generator or on a memory card.
