Radio frequency anechoic test chamber R&S®ATS1500C

anechoicelectromagnetictemperature

Overview
The R&S®ATS1500C is a transportable compact antenna test range (CATR) fully anechoic chamber designed for automotive radar sensor development, validation and calibration. It integrates a gold-plated parabolic reflector, a high-speed two-axis (tilt-tilt) 3D positioner and a universal feed antenna providing parallel access to both polarizations. An optional RF‑transparent enclosure enables automated temperature testing from -40 °C to +85 °C without degrading RF measurements.

Key facts

• In-band OTA measurements for 60 GHz and 76–81 GHz radar sensors
• CATR with high-precision gold-plated reflector and 30 cm diameter quiet zone
• Compact footprint: approx. 1.3 m²
• High-speed, high-precision two-axis (tilt-tilt) 3D positioner
• Optional temperature enclosure for -40 °C to +85 °C automated testing

Features & benefits

• Far-field conditions in a compact chamber: the CATR reflector recreates indirect far-field wavefronts and produces a 30 cm quiet zone, enabling aperture and antenna characterization within a 1.3 m² footprint.
• R&D, calibration and validation: compatible with radar echo generators (e.g., R&S®AREG800A) and test instruments to simulate targets (range, velocity, RCS), perform module calibration, RF validation and interference testing with high repeatability.
• Premium chamber performance: fully anechoic design with shielding effectiveness > 90 dB and pyramidal absorbers optimized to minimize ghost targets for sensitive radar measurements.
• High-speed, high-accuracy positioner: tilt-tilt 3D positioner with adjustable height for DUT alignment, large tilt ranges and angular resolution down to 0.03° for precise angular measurements and calibration.
• Enclosure for environmental testing: RF-transparent, thermally isolating enclosure option allows heating/cooling of the DUT from -40 °C to +85 °C while keeping RF measurement integrity; enclosure supports mounting on the positioner (outer axis ±90°, inner axis ±15°).
• Integration & control: web-based GUI, Ethernet control with SCPI-like commands, trigger synchronization for external equipment and multiple feedthroughs for flexible DUT connectivity without compromising shielding.
