The main application of this receiver is in antenna tracking systems where the receiver provides the tracking signal level to the antenna step-track controller . The Beacon Receiver receives a satellite beacon signal which is down-converted to L-Band by a PLL stabilized Low Noise Converter (LNC) at its L-band interface input The Beacon receiver measures the input level in a user selectable defined bandwidth and provides this as a dB-linear and calibrated analogue output voltage.
