Compact Antenna Test Range (CATR)

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.

Multi Probe Anechoic Chambers (MPAC)

The Keysight multi-probe anechoic chamber (MPAC) family delivers a comprehensive solution for mmWave over-the-air (OTA) testing, enabling accurate validation of protocol conformance and MIMO performance. These systems support direct far-field measurements, multi-angle and multi-beam analysis, and full spherical coverage, ensuring realistic and repeatable test conditions. Optimized for 5G NR FR2, beamforming, and radio resource management (RRM) validation, MPAC systems also support sub-6 GHz signaling, providing flexibility across a wide range of test scenarios. The chambers feature advanced multi-probe configurations, integrated positioning and alignment tools, low path loss, and a modular architecture that enables easy setup, scalability, and future expansion. MPAC configurations can be tailored to your specific needs—from compact setups for protocol verification to fully equipped systems for comprehensive 3D MIMO performance evaluation of the device under test (DUT).
