Spherical Near-Field Measurement System 1.3 meters

Description

Model: SNF-RAZ-1.3

Model SNF-RAZ-1.3 is a pre-configured three axes spherical near-field measurement system ideal for measuring low to medium gain antennas from 0.37 to 110 GHz. The system is constructed of high strength aluminum and can support AUT payloads of up to 75 kg (165 lb). The independent probe stand and AUT positioner are easy to assemble, align and can be quickly dismantled for transport or storage.

Capabilities
The SNF-RAZ-1.3 supports NSI-MI, Keysight, and Rohde & Schwarz RF receivers and is capable of measuring amplitude and phase patterns from UHF band to mmWave. The system includes a software workstation preloaded with NSI2000 Antenna Measurement Software and Windows® and provides automatic setup of scans based on measurement parameters and desired output. Measured data can be processed for far-field or holographic patterns yielding complete characterization of the antenna’s performance. A single data set provides information on antenna gain, side lobe structure, beam pointing and cross polarization.
