\
The PRG series remote mounted reference generation & distribution units from Peak Communications are designed to provide highly stable reference generation coupled with multiway fan-out, primarily for satellite earth station applications. Reference signal fan-out distribution has many advantages over cascade methods, including: no down-stream equipment loss of lock or mismatches associated with in-service cabling modifications, optimised & balanced signal levels presented to each connected unit, no loss of signal level when compared to a passive cascade approach. These units can be provided to give reference signals of 5, 10, 50 or 100MHz and are supplied with an optional external reference input to synchronise to the station clock, in which case the internal reference generation circuitry provides a back-up which detects the absence (in the event of a station clock failure or disconnection of the external reference) of the external reference and automatically switches back to the internal reference system. The PRG series units are DC powered and are constructed of high-grade components to give the ultimate stability performance. The PRG series units utilise a sealed chassis and are designed for mounting in outdoor, exposed locations and are fully weatherproof.
