Anechoic test chamber R&S®ATS1800C

radio frequency anechoictemperatureemission

Overview The R&S®ATS1800C is a CATR-based compact and transportable OTA anechoic chamber designed for far-field OTA RF measurements of 5G NR FR2 antennas, modules and devices. It supports R&D and conformance testing with wide frequency coverage, selectable quiet zones and modular extensions.

Key facts

• 3GPP-compliant CATR OTA chamber, transportable
• Frequency support up to 170 GHz (D‑Band)
• Quiet zone options: 30 cm or 40 cm
• Footprint: approx. 1.3 m²; mobile with wheels
• Automatic feed switcher option for OOB testing covering approx. 6 GHz to 110 GHz
• Optional RF‑transparent temperature enclosure: -40 °C to +85 °C

Features & benefits

• Compact and mobile: Small footprint and transport wheels enable flexible placement in R&D labs and test houses.
• High-performance CATR reflector: Bidirectional parabolic reflector optimized for mmWave; two reflector sizes to create different quiet zones.
• 3D positioner with hardware trigger: Azimuth-over-elevation positioner with high angular resolution and accuracy; supports heavy DUTs and accelerates TRP measurements.
• Flexible feed options: Motorized automatic feed switcher supporting up to four selectable feeds; single fixed feeds available for specific ranges.
• Environmental testing: RF‑transparent temperature enclosure compatible with 3D positioner for temperature-dependent RF measurements.
• Multi-angle IFF/RRM testing: Side-chamber extensions allow additional reflectors and multiple angles of arrival.
• Camera option: Visible and infrared monitoring for thermal observation during sealed tests.

Applications

• 5G FR2 antenna and module R&D
• 3GPP/CTIA conformance and TRP/beam characterization
• Out-of-band emissions and RRM testing across extended ranges
• Temperature-dependent RF radiation measurements
