The FDU-160i is a high performance signal distribution amplifier designed for use with Brandywine high precision time and frequency sources.
The FDU-160i is contained in a compact IU 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.
