NSI-800F-30双轴Phi/Theta远场天线量测系统
厂 牌 : NSI-MI
The NSI-800F-30 Dual axis Phi/Theta Far-field Measurement System is a cost effective solution that willallow the end user to eventually convert his far-field measurement system into a near-field measurementsystem. This system takes advantage of all the upgrade options recommended for the NSI-800F-10single axis far-field measurement system to convert it into a complete dual-axis phi-over-theta, highaccuracy stepper motor based positioning system. Beyond this, the NSI-800F-30 can easily be convertedinto an NSI-700S-30 Spherical Measurement System with the addition of NSI’s Near-field software.As with all NSI systems, this system is constructed of modular high strength aluminum and can support loads of up to 40pounds (18 kg). The location of the probe, theta and phi stages are fully adjustable to accommodate different antennasizes and mounts. This simple modular design is easy to assemble and can be quickly dismantled for transport or storage.
The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phasepatterns from L-band to mmWave Bands. The Model 800F-30 includes NSI Far-field Antenna Measurement Software.The system software runs on a Pentium based measurement workstation and provides automatic measurementparameter setup. Measured data can be displayed to provide complete characterization of the antenna’s performance.A single data set provides information on antenna gain, side lobe structure, beam pointing and cross polarization.The NSI-800F-30 can further be supplied with a variety of options to enhance system performance.
