Intelligent Wideband Frequency Distribution Amplifier

The FDA-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 FDA accepts two sets of inputs, comprising the reference frequency (typically 1-20 MHz) and status from the source. The FDA 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.
