Device for storage management and exchange of GB-magnitude waveform data

Abstract

The invention relates to a device for storage management and exchange of waveform data represented by an oscilloscope and belongs to the field of electronic measuring instruments. The device for storage management and exchange of the GB-magnitude waveform data comprises a sampling and imaging module, a serializer / deserializer, a data exchange module, a waveform imaging postprocessor, a video controller, a master controller, a PCI controller, an instruction parser and a displayer. The sampling and imaging module is in communication with the data exchange module through the serializer / deserializer. The data exchange module is in communication with the waveform imaging postprocessor. The waveform imaging postprocessor is in communication with the master controller through the video controller. The master controller is in communication with the serializer / deserializer through the PCI controller and the instruction parser in sequence. The video controller is electrically connected with the displayer. The device for storage management and exchange of the GB-magnitude waveform data can effectively store GB-magnitude waveforms and directly send the stored data, and can be widely applied to high-speed oscilloscopes.

Description

technical field [0001] The invention relates to an oscilloscope, in particular to a waveform data storage management and data exchange device in the field of electronic measuring instruments represented by the oscilloscope. Background technique [0002] The basic instrument represented by the oscilloscope is a relatively traditional and most basic general-purpose test instrument used for on-site or routine maintenance. The complexity of information is getting higher and higher, and the system is running faster and faster. The conversion rate is in the order of ns, or even in the order of ps. The amount of data is huge, and a complete piece of data ranges from hundreds of MB to as many as hundreds of GB. Traditional oscilloscopes that support the research and development, production, testing, and on-site maintenance of modern electronic information systems cannot fully meet the testing requirements. [0003] A detection and detection information system requires a data conver...

Problems solved by technology

The existing domestic oscilloscopes that support the testing and maintenance of this detection system are far from meeting the testing requirements, and the high-performance oscilloscopes on the foreign market, whether it is TEK, Agilent or Lecroy, have a continuous real-time storage capacity of no more than 200MB, which is far from enough. No more than GB to hundreds of GB real-time acquisition storage requirements
