[[NeoScan]] provides a unique and highly superior alternative to the conventional near-field scanning systems. Some of the very attractive features of the [[NeoScan]] probes are:
== One System for Both Near & Far Field Characterization ==

[[NeoScan]]'s non-invasive electro-optic probes have made it possible to directly measure and map the aperture-level fields of a radiating antenna. When dealing with radiating systems, mapping the near fields can have two different purposes. For the purpose of far-field radiation pattern estimation, you don't want to get too close to the surface of the antenna to avoid picking up all the reactive fields and evanescent modes. If you do so, you will need a rather high spatial resolution to capture the field variations with very precise details. On the other hand, for the purpose of diagnostic near-field mapping, you do need a very high spatial resolution and you want to maintain the field probe as close as possible to the surface of the antenna under test. [[NeoScan]] does both jobs for you and meets both sets of requirements with one system and the same probes.
== A Perfect Solution for Characterizing High-Power Antenna Systems ==

Test and evaluation of high-power antenna systems or active phased arrays is a daunting process. Special considerations must be taken into account when measuring high-power radiating systems in an anechoic chamber including operator's safety and fire hazards. The problems are multiplied when using a near-field scanning system whose metallic receiver probe has to be positioned at a far enough distance from the transmitting antenna under test. In contrast, [[NeoScan]] probes can handle field intensities as large as 2MV/m and can even withstand higher radiated power levels. The non-invasive EO probes can be placed very close to the surface of the high-power radiating aperture, while the optical mainframe and RF processing back end reside much farther at a reliable distance from the aperture.
