Untitled       x9a

OBJECTIVES:

To understand the complete working principles of the satellite receiver system and to explain the following, Reason for using high frequency for communication via satellite.

  • Assembling the dish antenna.
  • LNB mounting arrangement.
  • Faults due to dish antenna, co-axial cable and LNB.

To understand the complete working principle of Video signal uplink transmitter and downlink receiver system using high frequency (2.4GHz) signal for communication via in-door antennae

Lab Satellite Receiver Trainer is based on a modern and complete satellite receiver system consists of an external unit including parabolic antenna and LNB converter. This trainer is mounted in a sleek Anodized Aluminium cabinet defining a compact and functional set indicating the Block diagram of satellite Receiver in multicolour. Test points are provided on an easily accessible panel; the fault simulators are also provided in this trainer. The following objectives are explained in this trainer for the students to understand the complete working principles of satellite receiver system.
