Page 8: Introduction
Circuit Diagrams 1.2. Purpose The SAR-DF 517 product is a general direction finder, developed for professional SAR (search and rescue) purposes. This Direction Finder (DF) is a multiband type (118MHz…410MHz) working with the physical Doppler-Effect. It offers the possibility to bear and analyse traditional emergency frequencies in the UHF and VHF band and the maritime radio band .The Cospas/Sarsat emergency signal is bearable,... - Page 9 SAR-DF 517 The Display Control Unit (DCU) is the indicating and controlling instrument of all functions of the direction finder. It can be seen as an interface between the direction finder and the operator. The Antenna Unit (AU) contains the direction finder, prober, the “heart” of the whole system, comprising four modules.
