NSI-MI offers a dual-linearly polarized, high-performance probe covering 1.7–2.6 GHz. This probe is designed specifically for near-field antenna measurements and come with a typical probe pattern correction coefficients for PNF and SNF measurements*. It covers a typical half-octave frequency band aligning with the standard waveguide bands. Additionally, the probe features a circular aperture that is ideal for spherical near-field measurements with knife-edge profiles that minimize backscatter in planar near-field antenna measurements. Our probes are high accuracy calibration items that come with standard absorber and a mounting cage compatible with most NSI-MI positioners. This larger sized probe is shipped in a re-usable and durable shipping container to protect your investment and is manufactured to provide many years of useful life in the measurement facility.

*PNF and SNF probe pattern coefficients provided are compatible with the NSI2000 software. CNF probe pattern coefficients may be available. Probe patterns may be available for the MI-3000 software. For other availability and compatibility with other antenna measurement software please contact sales.
