机电部二十九所从美国引进的 SA2083E天线分析仪最高工作频率18GHz,而18GHz以上频段则对我们实行禁运。通过机电部二十九所的努力,对此 SA2083E 仪器进行二次开发,目前可用于对18～140GHz天线幅度、相位方向图和天线增益的自动测量,动态范围为70dB.
The electromechanical department 29 SA2083E antenna analyzers imported from the United States have a maximum operating frequency of 18GHz, while the frequency bands above 18GHz impose an embargo on us. Through the efforts of MEP 29, the SA2083E instrument is developed twice and is currently used for automatic measurement of antenna amplitudes, phase patterns and antenna gains of 18 ~ 140GHz with a dynamic range of 70dB.
