For measuring low-level signals in anechoic chambers

The R&S®AM524 low-noise active antenna system has been designed for measuring low-level signals in anechoic chambers. Criteria for dimensioning such antennas are different from active antennas used outside shielded rooms. The R&S®AM524 features maximum sensitivity, small dimensions and the capacity to handle large signal emissions from the EUT. The frequency range of 100 Hz to 1 GHz is divided into three subranges: 100 Hz to 30 MHz, 30 MHz to 200 MHz, and 200 MHz to 1000 MHz. An optional frequency range extension to 26.5 GHz is available with an additional antenna element.

Features & benefits

Extremely high sensitivity

For receiving even smallest emissions

The R&S®AM524 low-noise active antenna system is especially designed for measuring small signals in shielded cabins. Active antennas have been chosen for this task. External noise is a key factor when designing active antennas for general reception tasks. Use within shielded chambers means the optimization can focus on maximum sensitivity.

Excellent large-signal characteristics

For wide dynamic range

A measuring antenna must not only be as sensitive as possible but also provide a wide dynamic range. A sophisticated system of switchable attenuators, amplifiers and filters extends the range of measurable DUTs even to devices with large signal characteristics.

Wide frequency range

For current and future applications

With its three standard antenna components, the R&S®AM524 covers the wide frequency range required for current TEMPEST measurements. The optional frequency extension of up to 26.5 GHz means the R&S®AM524 is also prepared for future applications.

Especially suitable for TEMPEST measurements

Fufills all requirements of relevant standards

The R&S®AM524 is especially designed for TEMPEST measurements and its specific requirements. To provide customers a long-lasting solution, the antenna system will be continuously enhanced in line with relevant standards. If necessary, antenna system components can be upgraded individually.
