Satellite Trainer

SATELLITE TRAINER

The Trainer  is based on a modern and complete
satellite reception system, properly changed to improve the
learning experience on the design and realization of a reception
system, dealing also with repair and maintenance problems of
the plants including the satellite receiver.
rainer consists of an external unit including: parabolic antenna,
driven positioner, polarizer and LNB converter; and of an indoor
unit mounted on the Edubox® structure, defining a compact
and functional set where you can find: the electronic circuits; a
detailed silk-screen panel with block diagrams; 38 test points
mounted on an easily accessible panel; the 24-fault simulator
and the theoretical-experimental tests.
(*): the trainer is configured according to the user’s needs.
