RASTER

Some models of the Series 9000E Scanner/Decoder are supplied with a

raster scan option. Not only does the beam scan horizontally but it is

also incremented vertically so as to sweep an area. The area covered

depends on the raster deflection and the distance from the scanner. The

unit is available with 5

, 10

, 20

, and 30

deflection. Figure 3-6 below

shows the area covered for various deflections and distances from the

scanner. For 500-scan/sec. models, six sweeps of the beam are equally

spaced over the raster height. For 1000-scan/sec. models, twelve

sweeps are equally spaced over the raster height.
