14. RRERERE EFF Figure 15 Peak Detection Term interpretation Collecting mode The oscilloscope transforms the collected analog data into a digital form after they are gathered in the following three different modes that is sampling peak value detection and averaging values Sampling The oscilloscope takes samples from the signal at a equal time interval to reconstruct the waveform in this mode by which the analog signal can be expressed correctly in most cases yet the rapid changes can not be collected between two sampling time intervals causing the confusion and loss the narrow pulse in the signal probably Peak value detection The oscilloscope takes samples from the maximum and minimum of signals in each sampling interval and shows the waveform with the sampled data in this mode thus by which the oscilloscope may collect the possibly lost narrow pulse in the sampling mode but the noise is obvious Averaging values the oscilloscope collects several waveforms and average over them and displays the averaged waveform in this mode by which the random noise can be reduced Duration time When a new waveform is displayed the previous waveform shown on the screen does not disappear immediately only to be displayed for a period of time that is the duration time by setting which the waveform can be displayed more continuously and thus a display similar to that shown by the analog oscilloscope can be achieved Roll scan mode
