Model ASC300LW (930 MHz to 2300 MHz)

The Model ASC300-LW 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-LW are for antenna step track controlling and uplink power control system. Also can be used on telemetry beacons.

CDS, Continuous Digital Streaming (Optional)

The streaming option associated with the ASC300 series of beacon receivers provides a continuous, two byte, data stream running at 9600 baud that contains ten bits of signal strength level indication as well as lock or alarm condition of the unit. Other baud rates are available. A female DB9, RS-232 interface connector on the rear of the unit is specifically dedicated for this option.
