The AMS-8923 Antenna Measurement System includes a custom Multi-Antenna Array Ring. This ring houses a system of dual-polarized antennas. Together, these antennas support testing between 700 MHz and 6 GHz.

An integrated laser alignment system assists with DUT positioning. With a switch control box integrated on the ring, the test system provides fast switching between antennas for high speed testing. Its centralized system configuration supports easy maintenance and superior reliability.

Multi-Antenna Array

23 dual-polarized antennas spaced every 15º, with anechoic absorber material between provide high speed, accurate and repeatable test performance.
