Abstract In order to improve the maintenance support capability of the new generation weather radar and enhance the effectiveness of radar support,this paper proposes a design of oscilloscope input conditioning circuit design based on a portable radar maintenance test platform.Aiming at solving the problem that the impedance gear of onboard oscilloscope of the general test instrument cannot be switched automatically,this paper designs a conditioning circuit to realize the automatic switching of input impedance and the automatic measurement of radar-related parameters,and achieves the purpose of remote control,simple operation and stable operation,which provides technical support and guarantee for the popularization and application of portable radar maintenance test system.
