US 7,460,967 B2 · Selectable navigation to automatically discovered events within the acquisition record of a digital sampling oscilloscope

Abstract

Events discovered by an automatic measurement subsystem in the trace of a DSO are visited using a set of event navigation controls. In a TIME Mode the controls operate to display the first of those events, display the next event after the one currently displayed, display the previous event before the one currently displayed, and, display the last event. In a SEVERITY Mode the controls operate to display the best of those events, display the next best event relative to the one currently displayed, display the next worst event before the one currently displayed, and, display the worst event. The sets of navigation controls may be a mode control menu accompanied by four stylized arrow shaped buttons within a GUI that are clicked on by an operator using a mouse. One set of arrow shaped button can serve both modes, or different sets of buttons can serve each respective mode.

Dependent claims

A method of displaying selected portions of interest within a waveform measured by a digital sampling oscilloscope, the method comprising the steps of:

(a) measuring a signal's waveform with a digital sampling oscilloscope by sampling the signal's values and storing them as an Acquisition Record;
(b) defining criteria by which an Automatic Measurement Subsystem can locate events of interest within the Acquisition Record;
(c) subsequent to steps (a) and (b), traversing the Acquisition Record stored in step (a) to locate events therein that meet the criteria defined in step (b);
(d) storing in an event location table the locations in the Acquisition Record where there are events located by the traverse of step (c);
(e) subsequent to step (d), traversing the event location table of step (d) in response to activation of selected controls to do so;
and
(f) displaying upon a screen of the digital sampling oscilloscope a trace that represents the portion of the signal's waveform that corresponds to an entry in the event location table to which there has been a traverse in step (e).
