摘　　要：以往在测试EIRP值时一般采用人工测试的方法,这种测试模式不仅效率低,有时还会因人工操作影响测试结果准确性。本文提供了一种EIRP的自动化测试方法,通过一台上位机对相关设备进行自动数据采集并计算出卫星EIRP值,避免了传统测试方法的人工误差,具有高效性和实时性等特点。以FY3C532轨EIRP的测试为例,简要阐述这种自动化测试方法的测试过程。The measurement of EIRP （Effective Isotropic Radiated Power） is an important test in satellite on-orbit tests, which represents the quality of the communication link and receiving satellite data. The previous methods generally use the manual test, which is not only inefficient, but also has sometimes the low accuracy of test results. This paper provides an automated test method of EIRP, in which through a host computer to automatically collect the data and calculate EIRP. It avoids the artificial error of the traditional test method, which has the advantages of high efficiency and real-time. Taking the FY3C＇ s EIRP test as an example, the test procedures of the method are briefly described.
