Atlantic Satellite beacon receiver

Text Box: Functional Description

The Model ASC300–LW Beacon Tracking Receiver is a high performance unit that is designed to real time track the power density of a satellite beacon and output a temperature stabilized DC voltage that is linearly proportional to the beacon power by utilizing a true, RMS-responding power detector. The proprietary “SWEEP TRAC” option provide signal tracking capability for higher drift LNB’s. The applications for the ASC300-LW are for antenna step track controlling and uplink power control system.
