How does the NSI-700S-90 spherical near-field scanner compare to the SATIMO Stargate 64 or 128 scanner?
The NSI-700S-90 may be considered as an alternative to the SATIMO systems. It is a mechnically scanned system and is therefore slower, however, it allows for arbitrary angular sampling density (the SATIMO system is tied to the fixed probe spacing distance) and therefore allows wider frequency range to 18 GHz and higher. We also believe that it is a much simpler system to maintain, since there is only one probe and a positioner that needs to be serviced. Replacement of the probe by any other suitable version is also a very simple task. Dynamic range limitations of the “scattering modulation technique” may also be an issue for some applications.
