Waveform display style switching method and a digital oscilloscope

摘要

PROBLEM TO BE SOLVED: To display in the best manner the display style of filtered waveform (waveform without noise) and display style of unfiltered waveform (waveform capable of catching glitches) on an oscilloscope.;SOLUTION: An electrical signal is brought in step 900. The peak detect data samples from the electrical signal are stored in one or more memory devices in step 910. Filtered data samples or unfiltered data from the electrical signal are stored in one or more memory devices in step 920. Automatic switching is implemented to a first waveform display style, having the peak detect data samples configured in a first mode in step 940 when the unfiltered data are selected in step 930. Automatic switching is implemented to a second waveform display style having the peak detect data samples configured in a second mode, when the filtered data samples are selected in step 930 and step 950.;COPYRIGHT: (C)2010,JPO&INPIT
