Programmable Digital SCR LNB

Programmable DIGITAL SCR LNB

  • up to 24 User Bands
  • fully programmable configuration (number, bandwidth, center frequency, signal level, etc.) with XDiSEqC protocol
  • static mode of working (equivalent to SMATV head-end station)
  • dynamic mode of working (equivalent to SCR LNB)
  • User Band center frequency accuracy – 0.125 MHz
  • User Band bandwidth up to 82 MHz
  • coax cable loss compensation by signal level regulation
  • terrestrial input (47 – 700MHz)
  • software upgrade over coax cable
  • software version read-out
  • serial number programming
  • wide-band RF architecture (lower spurious, lower power consumption)
  • DiSEqC 2.0 communication
  • compatible with EN50494, EN50607 and dHello
