Ruggedized Have Quick / 1PPS Splitter

Time & Frequency Solutions’ Have Quick/1PPS Distribution Amplifier (HQS) is a small rugged, powered Have Quick/1PPS distribution module mounted in a 4” x 4” x 2.5” environmentally secure enclosure. The HQS can provide an MTBF up to 1 million hours depending on configuration.

The HQS is designed to facilitate long cable runs of both 1PPS and Have Quick signals for ships or aircraft requiring these timing reference signals at multiple locations. With the tested, ruggedised enclosure the HQS can be placed in difficult environments and difficult to reach places on ships and aircraft.  The unit is configurable at the factory for single ended or differential signals as required for the application. Various power options are also available upon request. Designed for “fit and forget” operation, the compact, reliable module provides an elegant solution for distribution of the timing references.
