Model ASC350L (930 MHz to 2050 MHz)

The Model ASC350L Beacon Receiver is a high stability 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.
