Terrasat IBUC 2 X-Band Intelligent Block Upconverter (7.9 - 8.4 GHz) 5W - 60W
High linearity, available with integral AC power supply or separate DC power supply, internal 10MHz reference, AGC or ALC circuits hold gain
IBUC 2 X-Band Intelligent Block Upconverter (7.9 - 8.4 GHz)
The Terrasat IBUC 2 X-Band series is the latest evolution of the Intelligent Block Upconverters (IBUCs) and has all of the advanced features and reliability of the original IBUC in a new, more compact package.
IBUC 2 offers significant benefits such as high performance in a compact, cost effective package, simple design and installation, simplified 1+1 configurations.
The IBUC 2 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 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 are internal AGC and ALC functions that satisfy demanding applications with stringent specifications.
