sat-nms LBRX19 - L-Band Beacon Receiver

The sat-nms LBRX19 L-Band Beacon Receiver, developed by SatService GmbH, is a precision measurement tool for satellite communication systems. Its primary function is to measure RF input levels and deliver this data to control systems, making it an essential component for tasks like antenna tracking and uplink power control.

Overview

The sat-nms LBRX19 is the 19-inch rack-mount version of the sat-nms LBRX Beacon Receiver. It supports up to four L-Band inputs via an integrated input switch with LNC power supply. For environments requiring a more compact solution, a DIN rail box version is also available.

This receiver does not demodulate satellite signals but instead uses a non-coherent measurement approach, ensuring it can handle modulated signals like FM or QPSK. It provides digitized signal-level information through multiple interfaces, supporting both local and remote operations.

Key Features

• Frequency Range:

  • Standard: 950 to 2150 MHz.
  • Optional: Extended tuning range up to 2450 MHz.
