Spherical Near-Field Measurement System 1.3 meters
Model: SNF-RAZ-1.3
Features
- 370 MHz to mmWave measurements
- Full spherical characterization
- Automatic scan setup
- Powerful plotting and antenna analysis software
- Far-field, near-field, and holographic patterns
This is a pre-configured 3-axis spherical near-field measurement system ideal for measuring low to medium gain antennas from 0.37 to 110.0 GHz. The system is constructed of high strength aluminum and can support antenna-under-test (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.

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.
