Abstract

PURPOSE: To reduce the measuring time by automatically measuring and indicating parameters of a waveform with the waveform with automatic compensation of a time relation between a signal to be measured and a trigger signal.
CONSTITUTION: A waveform searching is conducted with an automatic correction to indicate and measure the time relation between a signal 1 to be measured and a trigger signal while the signal is converted into a digital value at a given time which is stored in a memory 15. From the value stored, parameters of various waveforms are measured to descriminate the waveform of the signal 1. The sequence of sample values stored in a memory 15 and the sequence of new sample values are added sequentially at a fixed frequency in the processes of searching and sampling waveforms, and finally divided by the frequency. The results are stored in the memory 15 for averaging processing. The parameters of the waveform can be automatically measured and indicated with the waveform.
