Functional Description

The Model ASC350L 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 DC voltage that is linearly proportional to the beacon power by utilizing a true, RMS-responding power detector. The applications for the ASC350L are for antenna step track controlling and uplink power control system.

The ASC350L is a modular unit that is designed to be remotely controlled by means of a RS232 or RS422 interface. The compact design of the unit makes it ideal for mounting directly into a transportable antenna system where space is at a premium. All monitoring and control functions are provided by a common DB-15 connector. By utilizing a wide range of  DC voltage for powering the unit makes for a more flexible user interface.

The applications for the ASC350-L:

	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 ten bits of signal strength level indication as well as lock or alarm condition of the unit. Other baud rates are available. A male DB15 with dedicated pins, interface connector of the unit is specifically dedicated for this option. RS-422 is optional.
