  • Network Enabled Frequency Distribution Amplifier
  • Dual Frequency Inputs with Auto Failover
  • Low Phase Noise Reference Frequency Outputs
  • Programmable per channel amplitude
  • 1U 19” rack mount
  • Redundant Hot Swappable Power Supplies

The FDU accepts two sets of inputs, comprising the reference frequency (typically 10MHz) and status from the source. The FDU provides automatic changeover should one of the on-line source inputs fail.  Manual source select override is available on the front panel, or through the Ethernet interface.

A variety of status indicators are located on the front panel for instant visual feedback, together with manual controls for source selection. A 10/100 base T Ethernet interface provides full control over the functionality of the system, including reference selection and output amplitude (on a per channel basis). User control of the unit is via a built-in Web Browser with user-friendly graphical interface, or via SNMP v2c for system applications.

Applications for the FDU-160i include secure communications systems, satellite ground stations, digital television broadcasting and any system requiring highly reliable frequency outputs.
