Design of PXI Digital Storage Oscilloscope Module Based on FPGA

A digital storage oscilloscope module in automatic test equipment was designed based on PIX bus. The field programmable gate array (FPGA) is used as the logic control unit. The circuit of high speed ADC and FPGA interface, clock management, and high speed data access were designed based on hardware modules. The digital storage oscilloscope module was successfully applied to the practical test system, whose performance was good, stable, and achieved the desired design goals.
