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.
