Portable NTSC Pattern
Generator with S-Video,
Composite Video and
RF outputs
This handheld NTSC Pattern Generator is
powered by a 9 volt battery or AC adapter
providing NTSC color bars, crosshatch, dot,
staircase, circle, center cross, windows, and
a full range of color raster patterns. The outputs available are composite video via RCA
connector, a RF output BNC connector, or an
S-Video mini-DIN output. Signals can be produced as an interlaced or progressive scanning
mode.
