Did you miss our In-Person Short Course? Technical and engineering professionals who are looking to expand their knowledge of antenna measurements can do so with the help of NSI-MI's Virtual Short Course. Plus, additional add-on modules.

NSI-MI Quad Ridged Feeds (ANT-QRF) are used in antenna test range applications and have been designed to deliver a wideband frequency response.

Full-wave electromagnetic simulation of a Compact Antenna Test Range (CATR) is not trivial given its electrical size. Typically, the reflector geometry is simulated using asymptotic methods using an assumed feed pattern, while RF absorber and its effects are ignored.

NSI-MI Technologies’ line of Active Antenna Load Management (AALM) products maintains the anechoic integrity of a test environment while managing the radiation load when testing active antennas with on-board amplifiers.

NSI-MI Technologies’ rotary positioners are engineered to provide the optimum balance of outstanding performance, maximum power-density, and excellent application flexibility. 

AMETEK NSI-MI’s portable target simulation compact ranges uses the most advanced technology. We offer custom systems for simulating missiles, decoys, and more. 

AMETEK NSI-MI has developed solutions for automotive antenna testing applications. Our systems allow for the characterization of antennas for cell phones, GPS, satellite radio and more.

Our advanced Vector Measurement Controller can be used for fast, on-the-fly electronic testing, precisely coordinated with mechanical motion or other controlled or monitored test attributes.

New wireless devices require fast, accurate, and complex electromagnetic field measurements. Product and test complexity constantly drive increased speed and accuracy in electrical, time, and even spatial domains. The Vector Field Analyzer is a new instrument that connects these domains, meeting the demands of leading-edge development and production testing.
