Intelligent Frequency Distribution Amplifier

The FDU-160i is a high performance signal distribution amplifier designed for use with Time & Frequency Solutions high precision time and frequency sources contained in a compact 1U rack-mount chassis.

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.
