NSI2000 Standard Edition Software

NSI2000 Standard Edition Plot


The NSI2000 software represents a combination of experience and technology that stands ready to solve the toughest antenna measurement challenges. NSI2000 is a 32-bit multi-tasking Windows® application that provides an excellent array of features taking advantage of the recent advances in operating system technologies. NSI2000 includes a 3-D viewer to inspect near-field and far-field data in a 3-D dynamic mode. This package spans all four measurement domains and presents the user with a uniform interface. NSI2000 also controls acquisition and interfaces to all mechanical and RF hardware required to make a measurement.
