Abstract
A waveform measuring device comprising an A/D converter for converting an input signal into a digital signal, a memory storing output data from the A/D converter, a first trigger condition detecting unit for detecting a present input signal meeting a first trigger condition, a second trigger condition detecting unit for detecting a past input signal of a desired time which is remote from the present time and meeting a second trigger condition, and a trigger signal generating unit for generating a trigger signal when the trigger conditions of the first and second trigger condition detecting units are satisfied. The waveform of the input signal corresponding to a desired interval is displayed in accordance with the trigger signal from the trigger signal generating unit. The input signal to the second trigger condition detecting unit is given without reading it out of the memory.
