Abstract
PURPOSE:To detect a temporary waveform and to monitor an indefinite phenomenon by dividing an input waveform in time series, digitizing and storing it in a memory successively, and then digitally recording a desired part under preset trigger conditions. CONSTITUTION:A signal inputted to an input terminal 1 is divided and digitalized in time series by an A/D converter 2, whose output is supplied to and stored in a memory 3 temporarily. Programs for fundamental waveforms and elements that the input waveform contains are generated previously and given simple abbreviations and codes as titles, and they are stored as trigger conditions in the memory 3. A user inputs desired one of the trigger conditions from a keyboard 5 to a CPU4 to read one, which coincides with the input trigger condition, out of the memory 3 and it is recorded digitally on a printer 5.
