Functional Description

The Model ASC300Ku2-I Beacon Tracking Receiver is a high performance self-contained 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 ASC300Ku2-I will tune over Ku band satellites (N. America 11.70-12.20 GHz) by utilizing an internal block down converter. The frequency band must be customer specified.

* CDS Continuous Digital Streaming
The streaming option associated with the ASC300 series beacon tracking receiver 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.
