R&S®AM524 Antenna

Low-noise Active Antenna System

  • Overview

Key facts

The Active Antenna System R&S®AM524 has been designed for measuring low-level signals in anechoic chambers. Criteria for dimensioning such antennas are different from those of active antennas used outside shielded rooms.

Features

  • Extremely high sensitivity
  • Excellent large-signal characteristics
  • Wide frequency range

Specifications

Model Frequency range (in three subranges)
R&S®AM524 100 Hz to 1 GHz

Key facts

  • 100 Hz to 1000 MHz
  • For measuring low-level signals in anechoic chambers

    The Active Antenna System R&S®AM524 has been designed for measuring low-level signals in anechoic chambers. Criteria for dimensioning such antennas are different from those of active antennas used outside shielded rooms.

    Essential parameters for antennas used in anechoic chambers are for instance low dimensions, high large-signal immunity and maximum sensitivity.
