Revealing the next generation in microwave receivers, NSI-MI presents the VFA™.
The Vector Field Analyzer™ (VFA) incorporates the latest technology for making antenna, radome, and electromagnetic field probing measurements. This simultaneous multi-channel precision measurement receiver adds powerful new capabilities to display polarization parameters. When used with a dual polarized probe, the Vector Field Analyzer™ measures both polarization ports and calculates key polarization parameters. Results include axial ratio, tilt angle, sense of rotation, and displays of the polarization ellipse. The Vector Field Analyzer™ combines the best RF performance, fastest measurement speed, and most advanced features available in the industry to create the foundation of a state of the art measurement system.
