IBUC R C-Band Intelligent Block Upconverter
The Terrasat C-Band IBUC R Series has all of the advanced IBUC features and the upgraded RJ45 M&C connector. This block upconverter offers significant benefits including low terminal cost, simple design and installation, superior RF performance and a reliable 1+1 configuration. Available in a wide range of RF power outputs including 80W, 100W, 125W, 150W, 175 and 200 watts.
The C-band IBUC R Series also provides new interfaces for connecting you to extensive M&C facilities for network management or local access. This powerful M&C enables trouble‐free commissioning with easy, point‐and‐click installation/configuration, continuous verification of performance with time‐stamped alarm history and simplified monitoring of terminal status
IBUC-R comes with a complete set of diagnostic tools including:
10 MHz input detector Input voltage and current monitoring Transmit L‐band input level detector Transmit RF output level detector User configurable thresholds and alarms
Unique to the IBUC are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
