CATR Anechoic Chamber 2 MA8172B

The MA8172B CATR Anechoic Chamber 2 is a compact Over-the-Air (OTA) test solution designed to support 3GPP-compliant 5G NR testing using the Compact Antenna Test Range (CATR) method. It enables 2 Angle of Arrival (AoA) Radio Resource Management (RRM) tests to evaluate UE communication quality and handover stability in base station transitions — all within a space-efficient setup..

  • Specification

The CATR Anechoic Chamber 2 MA8172B by Anritsu is engineered for advanced 5G NR OTA testing in research and development environments. Using the 3GPP-defined Compact Antenna Test Range (CATR) methodology, it simulates far-field conditions in a compact footprint, making it suitable for modern test labs where space is limited.

A key advantage of the MA8172B is its ability to support 2 AoA (Angle of Arrival) Radio Resource Management (RRM) tests, allowing engineers to assess UE communication quality, signal reception, and connection stability during base station handovers. This dual-angle capability is essential for accurately validating device performance in complex 5G networks.

It is fully compatible with the earlier MA8172A, offering seamless integration into existing Anritsu OTA test setups. The chamber's precise measurement environment and enhanced multi-angle evaluation features make it an essential tool for 5G mobile device testing, antenna characterization, and performance assurance in real-world handover scenarios.
