Fast, Accurate OTA Measurements Across Your Workflow

Keysight’s Compact Antenna Test Ranges (CATR) deliver highly repeatable over-the-air measurements from sub-6 GHz to mmWave frequencies in compact, integrated enclosures. Designed for 5G, 6G, and satellite communication device testing, as well as antenna measurements and phased array calibration, these turnkey chambers combine precision reflector technology, wide angular coverage, and low-reflection environments to enable consistent, standards-compliant results without the footprint of a full anechoic chamber. Whether you’re performing R&D, conformance, or production testing, Keysight CATR chambers support high dynamic range, fast switching, and automated test control to accelerate your device evaluation with confidence. For applications requiring larger test volumes, Keysight also offers custom solutions with quiet zones of up to 2.4 meters, enabling accurate testing of heavier and larger devices such as base stations, satellites, and radar systems.
