Precision Frequency Distribution

A range of quality frequency distribution units, including features such as dual inputs with automatic changeover and multiple independently-buffered outputs. Our products cater for a wide range of input signals, including IRIG A, IRIG B, Have Quick, 1PPS and low phase noise reference frequencies.

A broad range of quality Frequency Distribution Units that have gained a worldwide reputation for their reliability, flexibility and low phase noise in critical timing applications.


Features commonly include dual reference inputs with automatic “hitless” changeover and multiple independently-buffered fault tolerant outputs. The product range caters for fixed frequency 1MHz, 5MHz, 10MHz applications as well as wider band signals in the range 1MHz - 20MHz.  


Many units provide automatic signal status monitoring and alarms along with intuitive, secure and easy to use network based user interface.  Click here for overview guide

The FDU-240 Frequency Distribution Unit is a high quality, precision frequency distribution platform offered with a number of functional variants.  Applications for the FDU-240 include reliable signal distribution in systems designed for satellite ground stations, secure military communications and range timing.

The FDU-240 base unit model has twenty-four low phase noise sine wave outputs available at the rear panel via BNC connectors in response to one (Ref A) or optionally two (Ref A & Ref B) signal source reference inputs feeding the transfer switch.

Base level units units provide a precision OCXO frequency standard, while TCXO and Rubidium oscillators are available to deliver a variety of price and performance options. A combination option employing a low noise OCXO phase locked to a rubidium is also available, offering the low noise characteristic of an OCXO with the long term stability of a rubidium.

The FTSU range of signal distribution products provide precision programmable frequency and pulse signal amplification, synthesis and distribution in a variety of commonly utilised combinations. These devices deliver favourable performance in high integrity applications such as secure communications systems, satellite ground stations and digital television broadcasting where long term reliability and signal quality are depended upon.

The standard FTSU accepts two sets of input signal source normally comprising 1PPS and the reference frequency (typically 10MHz) delivering automatic “hitless” reference changeover should one of the continuously monitored on-line sources fail.  Each input reference can be automatically selected by a status signal from the source or manually selected from the front panel or remote Ethernet interface on programmable variants.
