    Model No: NSI-700S-90-CTIA
Wireless Antenna  & CTIA  Testing

 

 
DESCRIPTION

The NSI-700S-90 is an ideal system for measuring antennas in the wireless industry. It is a versatile system designed for testing electrical small antennas and for mobile station testing per CTIA OTA test requirements. The NSI-700S-90 uses an overhead dielectric swing-arm for probe motion in the theta axis, and a dielectric AUT support stage for motion in the phi axis. The overall system is specifically designed to eliminate the adverse effects from interactions between the AUT and the surrounding environment. It is the ideal solution for providing complete 3D characterization of the antenna or wireless device.
CAPABILITIES

The NSI-700S-90 includes the industry-leading NSI Antenna Measurement software and CTIA OTA software. The testing can be executed in far-field and spherical near-field modes for complete characterization of the antenna’s performance. The system can provide single cuts, complete 3D analysis capabilities, holographic back projection capability, and more. The CTIA OTA software is compliant with the “Test Plan for Mobile Station Over the Air Performance,” and the system is designed to be part of an overall CTIA Authorized Test Laboratory (CATL).
