.1 Gsps, Digital Storage Oscilloscope Spreadsheet Software Design

As a common test instrument in time domain, Digital Storage Oscilloscope has been widely used in various fields. Besides all the functions and the advantages that the Digital Storage Oscilloscope possesses, ScopeMeter have the functions of Digital Multi-Meter. Due to the features of small volume, little weight, low power consumption and built-in battery, ScopeMeter is especially fit for the field environment, no-power system, mobile occasion. With the development of the electronic measuring technology, measuring technology is geared to automated, intelligent and network directions. Digital storage scopemeter is widely used in various fields the important measuring apparatus.The main attributions of this dissertation include:⑴The design of data acquisition system and system control modulesThe design of data acquisition system. It is the core of digital storage Scope-Meter. Based on the ARM+FPGA structure, the Scope-Meter with the equivalent sampling frequency of 25GSPS, bandwidth of 200MHz is developed by adopting real-time sampling and random sampling. The data acquisition system and system control modules realize A/D control,channel control, time-based and selection the way of data acquisition.⑵The design of waveform computing and parameter measurement moduleThe design of waveform computing and parameter measurement module is focus on base waveform computing ,FFT and base parameter measurement,key parameter measurement.⑶The design of waveform processing and display moduleIn this module,wo realize waveform average, the peak detection and afterglow and waveform display ,character display and the design of display menu.
