Mini OTA test system
Product overview: ota2306 is a mini type GPS and gnssota shielded darkroom system. The system design is based on the user experience and comprehensively considers the environmental attitude and other factors. The standard far-field with a working frequency of 500mhz-3000mh and B sampling distance of 1000mm is designed. The probe designed for GPS and GNSS frequency is from stability, directivity, gain and polarization The parameters of sensitivity, gain and direction can be measured accurately. With the gnsstp test platform and related instruments of changeself, it can support all active tests in GPS and GNSS working frequency bands, which provides powerful help for you to quickly find the problem.
Hardware system of mini OTA test system:
Design features of mini OTA test system
1. The shield shell of ota2306 is designed as upper cone and lower rectangle, with the overall dimension (L) 1045x (W) 900X (H) 2585mm & plusmn; 5mm, which can be moved.
2. The shell is bended and shaped with rice gold and casters, which is convenient for moving and solves the handling difficulties caused by small doors and elevators.
3. The screen door adopts a special design of two conductive nets combined with a more flat all alumina door, with a shielding capacity of ＞ 80dB and easier switching.
4. The interior is fully paved with environmental protection absorbing materials, and the anti odor and formaldehyde are qualified.
5. Ota306 adopts vertical circular polarization measuring probe. The maximum diameter of phi surface is 230mm.
