Indoor far-field darkroom
At present, it is the largest indoor far-field anechoic room in the field of mobile communicationThe performance of the anechoic chamber in the early stage of construction, after strict simulation, the main reflection area adopts 1.6 meters high absorbing material; The Fresnel area adopts Chebyshev wave design to optimize the performance of the anechoic chamber. After the completion of the construction, after 203 rigorous testing, the performance test results are better than the design indicators; Compared with other testing sites in the same industry, it has more superior performance.
the far-field anechoic chamber is the largest anechoic chamber in Asia at present. The larger the size of anechoic chamber, the larger the test static zone, the farther the receiving/sending distance, and the
…
the efficiency of the dual-channel frequency sweep measurement system is improved by 8 times compared with the traditional dual-port frequency sweep measurement system. The system is equipped with two 8-port
…
the system can create a “test scheme”, the scheme content contains frequency point, turntable rotation information, power amplifier, speaker selection, downward inclination and other information, can prevent operation errors, error
…
compared with the traditional test turntable, the U-shaped test turntable has two test rotating surfaces, and the antenna test does not need the horizontal/vertical flip switch attitude. For MIMO antenna service beam testing, the horizontal beam
