sat-nms LBRX19-161 - L-Band Beacon Receiver

The sat-nms LBRX19-161 L-Band Beacon Receiver, designed by SatService GmbH, is an advanced RF measurement tool ideal for systems requiring precise signal tracking and control. With its unique 16:1 signal input switch, this receiver can handle up to 16 distinct inputs, making it highly versatile for modern satellite communication systems.

Overview

The sat-nms LBRX19-161 is a high-performance beacon receiver that measures RF input levels and outputs this data for control applications. It works in tandem with a PLL-stabilized Low Noise Converter (LNB), which down-converts satellite signals to the L-Band range. This device is optimized for applications like antenna tracking and uplink power control, providing accurate and reliable signal-level measurements.

Unlike conventional receivers, it does not demodulate signals. Instead, it uses a non-coherent approach, ensuring compatibility with various modulated signals, including FM and QPSK. This makes it a robust solution for environments where signal characteristics vary.
