    NSI-100V-1x1
 1' x 1' (300 mm x 300 mm) Vertical Planar Near-field Measurement System

DESCRIPTION

The 100V-1x1 is an ideal system for measuring high frequency medium and high gain antennas (>15 dBi) with small apertures. The 100V-1x1 is based on a vertical "T" frame design and is constructed of modular high precision linear stages. This simple design is portable and easy to align and can be quickly reconfigured to use both mm-Wave modules or traditional coaxially connected probes. The scanner is mounted on a 23.6" x 23.6" x 0.5" (600 mm x 600 mm x 12.7 mm) breadboard with M6 tapped holes on a 25 mm grid. The scanner includes a cable management system and can support probe payloads of up to 10 lb (4.5 kg).

The NSI-100V-1x1 System includes:
- X-Y Vertical Planar Scanner with cable management system
- Y tower absorber kit
- Mounting plate with leveling feet
- Motor control unit
- Workstation computer with keyboard & monitor
- NSI2000 Measurement and analysis software

CAPABILITIES

The system interfaces with a wide variety of RF equipment and is ideal for characterizing small aperture antennas from 8.2 - 500 GHz. The system software runs on an Intel based measurement workstation 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 complete characterization of the antenna's gain, side lobes structure, beam pointing and cross polarization. The Model 100V-1x1 can be integrated with a mm-Wave VNA, providing a compact mm-Wave planar nearfield test package. RF up and down conversion modules can be mounted directly on the scanner, implying that NO cabling changes need to be made.
