AMS18G 3D Antenna Measurement System

Overview
The new AMS18G series Antenna Measurement System is a compact, user-friendly system suitable for both indoor and outdoor antenna measurements. It comes with a dual-axis rotating platform (elevation plane and azimuth plane) and an integrated antenna plotting software. It is fully customizable for use with various types of vector network analyzers.

Sample MATLAB® codes are also provided for 2D/3D antenna pattern plotting.
