The Precision Axis Controller (ELE-PAC) is the latest high-performance position controller from NSI-MI. The modular and flexible design has been specially optimized to support all types and sizes of measurement systems. 

Balancing the performance and cost of antenna measurement RF sub-systems is an important part of the design process. Small or low frequency systems often use a centrally located vector network analyzer without any remotely installed RF electronics. As these systems get larger or the frequency increases, the need to locate RF components remotely to maximize the available dynamic range grows.

Phased array, and more specifically Active Electronically Scanned Array (AESA) technology has been in use for several decades. This type of array uses active components to control the phase and amplitude weighting of individual elements or groups of elements to modify the array’s aperture distribution.

This broadband ridged antenna is the perfect choice for spherical near-field measurements and far-field range illumination. With its wide frequency bandwidth, it can replace several standard Open-Ended Waveguide probes or horns.

Our range of standard gain horn antennas are used in antenna test range applications and have been designed to deliver accurate gain reference and reliable antenna gain measurements.
