In order to meet the requirements of high efficiency,low cost and batch testing for radiation effect evaluation of aerospace commercial off-the-shelf(COTS)devices,a general radiation effect test system for COTS devices was designed by analyzing the similarities and differences of different radiation effect tests of typical COTS devices.The test system is composed of peripheral component interconnect(PCI)extensions for instrumentation(PXI)system and field programmable gate array(FPGA)-based monitoring mainboard.It is applicable to the ground simulation test of single event effect and total ionizing dose effect of typical COTS devices such as FPGA,analog-to-digital converter(ADC),static random access memory(SRAM),operational amplifier,power chip,etc.It can measure the power consumption current,logic function,output signal and other parameters of the device under test in real time online,and can measure the input voltage,input current,output voltage and other functional performance parameters requiring high-precision measurement shall be measured offline.Through the single event and total ionizing dose effect tests of typical devices,the online and offline test functions of the test system were verified,which shows that the test system can meet the test requirements.
