The systems in this series represent the ideal solution to problems of synchronization for distribution networks of broadcasting signals. They make it possible to obtain a high-precision frequency source wherever there is an available GPS signal or analogue video signal that is, on its turn, locked to a precise reference.

The GPS receivers, design in “Carrier Aided Tracking” technology with 12 parallel channels, are available in single versions or redundant versions with automatic switch-over. Distributors are available, moreover, for frequency reference signals as well as for timing-reference signals.

The discontinuity of the presence of the reference signal does not jeopardize operation of the equipment, thanks to the substantial stability of the oscillator. The video signal synchronization systems are multistandard and may be equipped with demodulators in order to extract a single reference signal from a received program.

The sturdiness of the system in case of reference signal lack was obtained by comparing the local source frequency with the reference signal frequency and correcting the possible drift of the local frequency of the integrated oscillator. The offset units allow shifts in 1 Hz or 0,999000999 Hz to permit operation of the unit according to the various standards
