NSI-900H-2x2
 Ultra Lightweight Tiltable Planar Scanner

DESCRIPTION

Model 900H-2x2 is a turn-key system designed specifically for flight line antenna or satellite feed antenna testing applications. The 900H-2x2 is based on a rigid box-frame design and is constructed of modular high strength aluminum. The scanner can be set up in a vertical or horizontal orientation depending on the requirements. The system consists of a 2' x 2' (0.6 m x 0.6 m) ultralight weight planar stepper-motor-driven XY scanner, system controller, PC based workstation and near-field data collection and analysis software. The system includes a probe polarization and Z-axis positioner.
CAPABILITIES

The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phase patterns from X-band to mmWave Bands. The system includes NSI Antenna Measurement Software.

The system software runs on a Pentium based 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 lobe structure, beam pointing and cross polarization.

The Model 900H-2x2 can be supplied with a variety of options to enhance system performance. System mounting options are a mobile optical stand or a precision guide rail test fixture as shown in the photos.
