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 provides signal tracking capability for higher drift LNB's.

	Antenna Tracking Controllers
	Uplink Power Controllers

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