X-Band Intelligent Block Upconverter (IBUC)

The revolutionary Terrasat X-Band Intelligent Block Upconverter (IBUC) has advanced features to take your network to new heights.

IBUC Advantages

  • Integrated BUC/SSPA for higher performance and reliability.
  • DC power can be supplied via IFL coax or separate DC con-nector for 5 W through 20 W models.
  • All models available with integral AC power supply or separate DC power supply.
  • Internal 10MHz reference option automatically switches to internal reference when external reference is not available.
  • Guaranteed rated output power across the entire operating temperature range and frequency band.
  • Embedded Web pages provide management for small networks using any Web browser.
  • AGC or ALC circuits hold gain or output level constant.
  • Customer-selectable gain makes it possible to compensate for cable and terminal losses.

Advanced user interfaces:

  • TCP/IP HTTP with embedded web pages.
  • SNMP
  • TELNET through TCP/IP
  • FSK through TX IFL cable.
  • RS232/485 serial port.
  • Handheld terminal

IBUC offers significant benefits:

  • Low terminal cost
  • Simple design and installation
  • Superior RF performance
  • Simplified 1+1 configuration

New interfaces connect you to the IBUC’s extensive M&C facilities for network management or local access. This powerful new M&C enables:

  • Trouble-free commissioning with easy, point-and-click installation/ configuration
  • Continuous verification of performance with time-stamped alarm history.
  • Simplified troubleshooting of terminal faults.

The IBUC 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.
