Abstract: This paper mainly introduced the design of The testing and control apparatus for equipment used in microwave-switch's longevity validation.The testing and control apparatus can remote control and collect data of microwave-switch,control vacuum pumps and heaters on the equipment,measure the pressure and temperature in the vacuum,and offer human-computer interface.The testing and control apparatus can also protect the microwave-switch from fault mode. The central processing unit of the apparatus is the DSP system,which achieve all the Real-time control and testing.The human-computer interface is provided by aTouch Control integrative Machine,which can receive and display the data and save them.
