【Abstract】 The signal characteristic in the switch apparatus test was analyzed in this paper. Signal transform, isolationand synchronization trigger technique has been researched. Based on the linear light coupled devices (SLC800), we designed a circuit of signal transform and isolation. The highly speed data sampling and processing is implemented by using industry control computer.更多还原
