Waveform recording is also convenient for our later on graphical analysis and calculation, spectrum analysis, correlation analysis and other operation curve. Universal electronic oscilloscope low prices, we are equipped with conventional instruments, but does not have the signal recording function, therefore, to design a signal waveform recorder, which can combine with general electronic oscilloscope, to observe the non repetitive signal waveform, is of great practical significance. This paper is based on the single chip microcomputer and the design of the waveform recorder, waveform storage system equipped with a A/D converter, data memory, using bipolar output prosperity D/A converter device. The system has ...
