Text Box: Functional Description The Model ASC300–70 Beacon Receiver is a high performance unit that is designed to real time track the power density of a satellite beacon and output a DC voltage that is linearly proportional to the beacon power by utilizing a true, RMS-responding power detector. The applications for the ASC300-70 Beacon Receiver are for antenna step track controlling and uplink power control system.       Text Box: 259 Expressway Court Virginia Beach, Virginia 23462 Text Box: Phone: 757-318-3500 Fax: 757-318-7020 Email: sales@atlanticsat.com www.atlanticsat.com
