sat-nms KaBRX19/Ka2BRX19 Ka Band Beacon Receiver

The sat-nms KaBRX19 Ka-Band Beacon Receiver by SatService GmbH is a highly versatile and reliable measurement tool designed to measure RF input levels and provide this information to control systems. The receiver is particularly suited for antenna tracking systems, uplink power control, and pilot measurement applications. Below is an in-depth analysis of its features and functionality.

Overview

The sat-nms KaBRX19 operates in conjunction with a Block Down Converter (BDC), which includes two local oscillators to cover a wider frequency range. This configuration defines the input frequency range of the Ka-band receiver, making it ideal for modern satellite communication systems. It does not demodulate satellite signals but instead focuses on modulation-independent level measurement, ensuring compatibility with various signal types, including FM and QPSK.

Key Features

• Wide Frequency Coverage:

  • Ka-band tuning ranges available between 17,300 MHz and 22,000 MHz.
  • High precision with a 1 kHz step size.

• Modulation-Independent Operation:

  • Ensures accurate level measurement regardless of signal modulation type.
  • Prevents unpredictable locking on PM/PSK side carriers.

• Compact Design:

  • Housed in a 1RU 19” rack-mountable unit.
  • Equipped with a front panel LCD display and keypad for easy local control.

• Interface and Control:

  • Provides signal level information via:
    • HTTP web interface through an internal web server.
    • UDP datagrams.
    • RS232 interface.
    • dB-linear analog output voltage.
  • Remote control via TCP/IP interface with HTTP requests or serial Monitoring and Control protocol.

• Input Flexibility:

  • Single input port (sat-nms KaBRX19) or dual input ports (sat-nms Ka2BRX19) for handling X/Y polarizations.
  • Input port selection can be performed locally or remotely through software.

• Additional Features:

  • 14/18V, 0/22kHz interface for managing switches and matrices on the L-band interface.
  • Relay contact output for level alarms.
  • Electronically calibrated for excellent level and temperature linearity, ensuring reliability in outdoor environments.
  • Unlimited remote clients supported for monitoring and control.

Applications

• Antenna Tracking Systems:

  • Delivers accurate tracking signal levels to step track controllers, ensuring precise antenna alignment.

• Pilot Measurement:

  • Ideal for monitoring pilot signals in satellite communication systems.

• Uplink Power Control:

  • Assists in stabilizing uplink power levels to maintain consistent communication quality.

• Stand-Alone or Integrated Operation:

  • Functions as an independent unit or integrates seamlessly into the broader sat-nms NMS Network Management System.
