Product ManualManual

The Evertz 1x4, 1x8 and 1x16 RF active splitter series provide amplification, slope compensation and distribution of RF Signals from 40MHz to 3GHz. They handle any RF input modulation format and provide 4, 8 or 16 isolated outputs for further signal distribution.

The DA4 models occupy one card slot, whereas DA8 and DA16 models occupy two card slots and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

  • Cable slope compensation adjustable up to 15dB in 1dB steps
  • Low noise amplification and distribution of RF signals from 40MHz to 3GHz
  • Wideband frequency response for use with L-Band, 70/140MHz IF and off-air DTV signals
  • Wide dynamic range (-10 to -60dBm)
  • Output gain of -10dB to +20dB adjustable in 1/2dB step on 7703 versions
  • AGC mode with adjustable target level on 7703 versions
  • Fixed gain of 0dB on 7702 versions
  • Protocol independent - handles all modulation formats
  • Passes a 10MHz reference signal
  • Input RF signal strength monitoring on 7703 versions
  • Fully hot-swappable from front of frame
  • Optional LNB power (@ +13 or +18V DC with built-in current limiting) and 22kHz tone for LO control on 7703 versions
  • 7703-LNB versions include LNB current monitoring with adjustable alarm thresholds for monitoring LNB health
  • Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK® on 7703 versions
  • VistaLINK® capability is available when 7703 modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
