The UT-4579 Up Converter (Figure 1) is designed for use in communication systems, or
in satellite up-link data systems, for the transmission of SCPC, DAMA and TDMA
communication signals. The Up Converters also can be used in communications system
applications with full transponder HDTV and analog TV.
The converter is designed to be hard mounted in a standard 19-inch rack or cabinet, or to
be rack mounted using slide mechanisms provided with the converter to allow it to be
serviced without its removal from the rack. An internally mounted exhaust fan for
cooling is mounted on the rear of the chassis. An AC power connector, with an On/Off
switch, also is located on the rear on the chassis. A six-foot AC power cord is supplied
with the converter.
