DSP85 Digital Repeater (1/2 W and 1 W)

Technology Innovation

 
DSP (Digital Signal Processing) technology is utilized to achieve the highest level of performance and spectrum agility. DSP filtering provides unmatched selectivity and can be finely tuned to help overcome difficult RF problems such as adjacent channel interference. The CSI Digital Repeater permits re-tuning of multiple passband configurations, locally or remotely, with virtually no downtime. The Graphical User Interface allows for effortless set up and monitoring via a standard web browser. In addition, the CSI Digital Repeater supports SNMP which provides ease of integration with Network Management Systems.
