    Model ASC 300LW: Beacon Receiver (930 MHz - 2300 MHz)

Functional Description:

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 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.
