LNB GTDLNB1T

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)
