Model 1249B
NTSC Generator with RGB
The 1249B is ideal for comprehensive testing,
servicing and adjustment of video and televi-
sion equipment, television receivers, video tape
recorders, video monitors, closed circuit televi-
sion systems and components, and master
antenna systems and components.

Model 1211E
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 out-
puts available are composite video via RCA
connector, a RF output BNC connector, or an
S-Video mini-DIN output. Signals can be pro-
duced as an interlaced or progressive scanning
mode.
