Nearfield Systems Inc. - Positioners

Positioners

NSI manufactures small to medium size accessory positioners which can be purchased to augment the capability of your near-field or far-field antenna test range. For near-field scanners, we offer 2 sizes of probe translation stages. The smaller one is good for the smaller systems and higher frequencies, and the large stage is typically used on our large horizontal and vertical scanners. We also offer 2 options for the probe rotation positioner, depending on the size of near-field probes selected.

For cylindrical and spherical near-field systems, we offer a line of azimuth and phi rotational positioners to meet most antenna size requirements.

For far-field measurement systems, we have a number of az/el and el/az, or multi-axis configurations which may suit your needs.

See Positioners FAQ for more information.
