sat-nms KuBRX19/Ku2BRX19 Ku-Band Beacon Receiver

The sat-nms KuBRX19 Ku-Band Beacon Receiver and its dual-input variant, sat-nms Ku2BRX19, are precision RF measurement tools manufactured by SatService GmbH. These receivers are designed to measure the RF input level and provide this data to control systems, making them indispensable in satellite communication applications such as antenna tracking, uplink power control, and pilot measurement. Below is a comprehensive overview of the devices:

Overview

The sat-nms KuBRX19 is based on the reliable sat-nms LBRX L-band Beacon Receiver module, operating in tandem with a Block Down Converter (BDC). The system includes:

• A low Ku-band BDC (LO = 9.75 GHz).
• A high Ku-band BDC (LO = 10.6 GHz).

These BDCs expand the operational frequency range of the receiver, making it suitable for applications requiring wide coverage and precision. Importantly, the receiver does not demodulate satellite signals, allowing it to handle various modulation types, such as FM and QPSK, without interference.

Key Features

• Frequency Range:

  • Full Ku-band tuning range: 10,700 to 12,750 MHz.
  • Fine resolution: 1 kHz step size.

• Modulation Independence:

  • Measures RF levels without dependence on signal modulation.
  • Prevents locking issues on PM/PSK side carriers.

• Compact Design:

  • 1RU 19” rack-mountable unit for easy integration into existing systems.

• Local and Remote Control:

  • Local Control: LCD display and keypad on the front panel.
  • Remote Control:
    • Web-based interface via an internal HTTP server.
    • Supports UDP datagrams, RS232, and dB-linear analog output voltage.
    • Communication via TCP/IP, using HTTP requests or serial Monitoring and Control protocols.

• Input Port Options:

  • Single input port (sat-nms KuBRX19) or dual input ports (sat-nms Ku2BRX19).
  • Dual-input models allow connection of both polarization planes (X/Y), with software-controlled input port selection.

• Additional Features:

  • 14/18V, 0/22kHz interface for switch and matrix control at the L-band interface.
  • Relay contact output for level alarms.
  • Electronically calibrated for precise level and temperature linearity, ensuring accuracy even in outdoor environments.

• Scalability:

  • Designed to support an unlimited number of remote clients.

Applications

• Antenna Tracking Systems:

  • Supplies tracking signal levels to antenna step track controllers for precise alignment.

• Pilot Measurement:

  • Monitors pilot signals to ensure consistent communication quality.

• Uplink Power Control:

  • Stabilizes uplink power levels to compensate for environmental or operational fluctuations.

• Stand-Alone or Integrated Systems:

  • Operates independently or integrates seamlessly into the sat-nms NMS Network Management System.
