ABSTRACT:
An oscilloscope apparatus for scaling and displaying persistence data using interpolation. The oscilloscope apparatus acquires a waveform and accumulates persistence data of the acquired waveform in a results buffer. The size of the persistence data is selectable by the user. A processor scales the persistence data using an interpolation algorithm to the size of a buffer in the display. The user may select a region of interest within the persistence data for scaling and display. In this manner, the persistence data can be zoomed in/out and centered on the display. The interpolation algorithm may be automatically selected or set by the user from standard, bi-linear, bi-cubic, or super-sampling algorithms.
