摘　　要：卫星地球站上行系统的性能与链路中设备的工作状态紧密相关,不合理的电平设置,会影响整个地球站的上行能力、性能指标,严重时甚至会对设备造成损坏。首先对上行链路工作电平调测的原则和分析方法进行探讨,并对上行链路中的调制器、上变频器、高功放等关键设备的工作电平调测步骤进行了详细说明。The satellite earth station uplink system performance is closely related with the working status of the devices. The inaccurate pamameters setting will affect the whole uplink performance, seriously even cause damage to the devices. Discus- ses the principle and analysis method based on the working level measure of the devices in the uplink system, and illustrates the work level setting steps on the uplink key equipments-such as modulator, frequency converter, high power amplifier-in detail.
