Area and Scope of Experimentation:
  • To set up an active & passive satellite communication link and study their difference. To study the communication satellite link design: process of transmitting a signal to a satellite (UPLINKING), reception of same signal via satellite (DOWN LINKING) and functioning of transponder of a satellite.
  • To measure the baseband analog signal parameters in a satellite link.
  • To measure the signal parameters in an analog FM/FDM TV Satellite link.
  • To study the functionality of a satellite MODEM.
  • To study the phenomenon of Linear polarization.
  • To measure the C/N ratio.
  • To measure the S/N ratio.
  • To study the effect of fading and measure the fading margin of a received signal.
  • To measure the digital baseband signal parameters in a satcom link.
