Intelligent Time Code Distribution Amplifier

The IBU-160i is a general-purpose frequency distribution amplifier designed for use with Time & Frequency Solutions high precision time sources, contained in a compact 1U rack-mount chassis

The IBU accepts two sets of inputs, comprising the reference input (100 Hz – 100 KHz) and status from the source. The IBU 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 for system applications.

Applications for the IBU-160i include test ranges, satellite control centres, shipboard time distribution, airports, rail terminals, and any system requiring highly reliable time code distribution.
