随着通讯事业的迅猛发展,电磁辐射自动测试系统越来越广泛地受到青睐。为使系统的性能价格比有较大飞跃,我们在设计中应用了主从式计算机结构。既可以现场手动操作,也可以远程自动测试,系统的自动化、智能化程度得到显著提高。 测试系统简介 测试系统如图1所示。被测电子设备置于转台中央,安装在天线塔上的接收天线以水平极化方式或垂直极化方式上下移动,直至计算机找到电磁辐射的最大值及方向。 天线的移动由电动机带动卷筒来实
With the rapid development of communications, automated testing systems for electromagnetic radiation are gaining popularity. In order to make the system cost-effective than a big leap in the design we applied the master-slave computer structure. Both on-site manual operation, but also remote automatic test, the system automation, the degree of intelligence has been significantly improved. Test System Introduction Test system shown in Figure 1. The tested electronic equipment is placed in the center of the turntable and the receiving antenna installed on the antenna tower is moved up and down by horizontal polarization or vertical polarization until the computer finds the maximum value and direction of the electromagnetic radiation. The movement of the antenna is driven by the motor
