【Abstract】 It discusses the design of a digital storage oscilloscope (DSO) module based on PXI bus, introduces the architecture of the DSO module. The design of the interface between PXI bus and DSO module is introduced. The technology of high speed real sampling is also discussed, and a method to improve the sampling speed by sample in different phase is provided. With this method, 200MHz real sampling is realized in the DSO module based on PXI bus.更多还原
