Abstract
A method and apparatus for displaying measurements of a waveform as icons on an oscilloscope. The apparatus acquires and processes a waveform thereby obtaining a number of measurements. Typically, the measurements are histograms, tracking measurements, and/or trending measurements. The oscilloscope displays both the waveform and a number of icons that respectively show the measurements. Each icon is a miniature rendering of the corresponding measurement and may be static, periodically updated, or a real-time preview of the actual measurement data which is calculated in the background by the oscilloscope processor. A user can select one of the icons to display the corresponding measurement at full size on the display.
