Used Miteq UPC-A a multi-channel uplink power controller that we sell with two interface cards per chassis. More cards are available if required.
The Uplink Power Control System (UPC) is a self-contained, rack-mountable unit, designed for geo-stationary satellite communication systems. It adjusts the strength of uplink signals at IF frequencies to compensate for varying weather conditions. The UPC can be setup completely from the front panel or over a remote bus via a host computer. All monitor and control functions are accessible at the front panel as well as over the remote bus.
A customer supplied Beacon Receiver provides the UPC with a DC voltage proportional to the downlink signal strength.
