[[NeoScan]] systems can be used as an essential tool for characterization, test and evaluation of antennas and phased array systems. The radiation patterns of antennas and arrays are traditionally measured in anechoic chambers. The size of the chamber, its architecture and the quality of the surrounding absorbers all affect the chamber's frequency range of operation and the accuracy of the measured results. Anechoic chamber facilities are very expensive, require a large space and are hard to operate and maintain. Compact near-field ranges are smaller replacements for full-sized chambers.
== NeoScan vs. Conventional Near-Field Scanning Systems ==

The [[NeoScan]] system provides a unique and highly superior alternative to the conventional near-field scanning systems. The [[NeoScan]] probes are optical and have absolutely non-metallic compositions. They are extremely small, can get very close to the surface of the radiating aperture, and provide ultra-wideband operation. Due to their non-invasive nature, [[NeoScan]] probes can generate ultra-near-field scans of the AUT. These can be used as an invaluable tool for diagnostic purposes. For instance, you can examine the inter-element coupling effects in passive and active phased arrays.
== The Perfect Solution for Characterizing High-Power Antenna Systems ==

Characterization of high-power active phased arrays is a very challenging task. Special considerations must be taken into account when measuring high-power antenna systems in an anechoic chamber including operator's safety. [[NeoScan]] probes can handle field intensities as large as 2MV/m and can even withstand higher radiated power levels. EMAG's unique probe and optical processing technology allows standoff distances as long as 50 meters between the probe location at the aperture of the high-power array and the optical mainframe and processing unit. This enables you to readily characterize very high-power antenna systems very accurately in a totally non-invasive manner without any serious safety or logistic concerns.
