Terrasat IBUC 2 Ku-Band Intelligent Block Upconverter (12.75 - 14.50 GHz)
Freq. range 12.750 to 14.50 GHz in Low, Std. and Ext. Ku, IF 950 to 1700 Mhz, Ethernet Monitor and Control, RF Output Interface WR75 waveguide
IBUC 2 Series Ku-Band Intelligent Block Upconverters
The Terrasat IBUC 2 Series Ku-Band is a revolutionary intelligent block upconverter with special advanced features such as a low phase noise, built-in M&C and increased efficiency. Integrated fully automatic gain control and ALC comes standard on all BUCs.
The Ku-Band IBUC 2 Series also provides new interfaces for connecting you to extensive M&C facilities for etwork 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 2 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-2 Ku-Band BUC are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
