Problems solved by technology

[0012] Obviously, when the traditional vector mapping method is used, the linear interpolation operation required for vector display doubles the amount of mapping data, so the time required to map each waveform data will also double, which will eventually lead to Sudden performance drop: The waveform capture rate of the system under vector display is much lower than that of point display, generally several orders of magnitude lower

Abstract

The invention discloses a vector mapping method for digital three-dimensional acquisition waveforms. After mapping the acquisition data of a waveform, the maximum value and minimum value of each column of data in the waveform data are statistically obtained, and by comparing the data of two adjacent columns The maximum value and the minimum value determine whether interpolation is required. If interpolation is required, select several elements within the interpolation range and add one to their element values ​​to complete the vector mapping of the digital three-dimensional acquisition waveform. In addition, after processing the waveform data collected this time, each column in the digital three-dimensional database can be traversed to obtain the current maximum and minimum values ​​of the column data, and the elements with a value of 0 between the maximum value and the minimum value can be Perform interpolation to further eliminate discontinuities. The invention controls the degree of vectorization by controlling the number of interpolation points, thereby shortening the vector mapping time and improving the waveform capture rate.

Description

technical field [0001] The invention belongs to the technical field of digital three-dimensional oscilloscopes, and more specifically relates to a vector mapping method for digital three-dimensional acquisition waveforms. Background technique [0002] There are two waveform display modes in traditional digital storage oscilloscopes: dot display and vector display. Point display is to directly map each real-time sampling data to its corresponding display pixel position. Its advantages are simple implementation and high capture rate. The disadvantage is that when the state transition time of the measured signal is much shorter than the actual sampling interval of the system, the It may not be possible to capture its edge, and the waveform display is sparse and discontinuous; the vector display is different from the point display, this method is to map the real-time collected data corresponding to a certain column, and the data between two adjacent columns The gap is filled wi...
