How to Store Maximum and Minimum Values for Peak Detect Modes in Digital Storage Oscilloscopes

摘要

The present invention relates to a method of storing a maximum value and a minimum value in a peak detection mode of a digital storage oscilloscope. In the method according to the present invention, a maximum value is detected for all equivalent sample intervals of input data in a first data collection period. In the data collection period, the minimum value is detected for all equivalent sample intervals of the input data, and the detected maximum value data and the minimum value data are superimposed and output on the screen. According to the method according to the present invention, after storing the maximum value data for all equivalent sample intervals in the acquisition memory, and after the first data acquisition cycle is finished, the obtained maximum value data is sent to the central operation memory, and then the second data Since the minimum value data for all equivalent sample intervals are stored in the acquisition memory in the acquisition cycle, the required acquisition memory capacity can be reduced by half.
