The 7803DA Active Splitters series provide amplification and distribution of RF signals from 40MHz to 3GHz. They handle any RF input modulation format and provide 4x, 8x or 16x isolated outputs for further signal distribution.
Monitoring of RF input power, card status, control of gain/attenuation of input, individual output gain/attenuation adjustment and slope compensation is provided remotely via VistaLINK® capability.
Direct fiber input feature is also available with accompanying with miniature 2307LR receiver. SmartMON™ capability allows inband monitoring data sent by a companion SmartMON™ enabled transmitter to be displayed locally or via SNMP/VistaLINK®.
The 7803DA4 model occupies one slot, whereas 7803DA8 and 7803DA16 models occupy two 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.
