| 摘 要： | 为了提高辐射杂散测试动态范围,通常需要在接受天线与测量仪器之间安装预放。测试过程中预放经常会产生额外的骚扰信号影响测试结果准确性,针对这一问题提出在接受天线与预放之间连接相应参数的滤波器,可以有效的滤除由预防产生的额外骚扰信号,该种测试方法可为各检测机构测试辐射杂散时提供参考。

| Abstract: | In order to improve the dynamic range of radiated spurious test,it is usually necessary to install a preamplifier between the receiving antenna and the measuring instrument. During the testing preamplifier often generates additional disturbance signals that affect the accuracy of test results. It is recommended to connect the filter with corresponding parameters between the receiving antenna and the preamplifier for this problem. It can effectively exclude additional disturbance signals generated by preamplifier. This test method can provide a reference for Testing agency when they test radiated spurious. |
