Abstract
Method and devices are described for visually detecting anomalies in non-repetitive signals. One device may take the form of an oscilloscope capable of displaying segments of a complete waveform record that includes non-periodic triggering events. The segments may be displayed vertically and horizontally offset from one another to aid in the visual detection of anomalies within the record. Decayed or aged segments of a waveform may also be simultaneously displayed.

A method for displaying, on a digital oscilloscope, triggered waveform records or triggered waveform segments of a single record along a sequence of primary waveform timelines that are offset along a secondary timeline, the method comprising:
- receiving and digitizing an analog waveform signal with an analog to digital converter;
- displaying, on a display section of the digital oscilloscope and along a first primary waveform timeline, a first waveform record or segment of the digitized waveform signal, comprising a first non-periodic triggering event;
- displaying, on the display section of the digital oscilloscope and along a second primary waveform timeline, a next waveform record or segment of the digitized waveform signal, comprising a next non-periodic triggering event, the next non-periodic triggering event occurring a non-zero elapsed time period after the first non-periodic triggering event, the second primary waveform timeline being substantially parallel to the first primary waveform timeline, the next non-periodic triggering event further being aligned with the first non-periodic triggering event on a secondary timeline transverse to the first primary waveform timeline and the second primary waveform timeline;
- and
- offsetting the second primary waveform timeline vertically and horizontally from the first primary waveform timeline and along the secondary timeline by an amount corresponding to the elapsed time period.
A method for displaying, on a digital oscilloscope, segments of a waveform along a sequence of waveform timelines, the method comprising:
- receiving and digitizing an analog non-periodic waveform signal with an analog to digital converter;
- displaying, on a display section of the digital oscilloscope and along a first waveform timeline, a first decayed waveform record segment of the digitized non-periodic waveform having a first variable image and a first non-periodic triggering event;
- simultaneously displaying, on the display section of the digital oscilloscope and along a second waveform timeline, a next decayed waveform record segment of the digitized non-periodic waveform, the next decayed segment having a next non-periodic triggering event and a next variable image that differs from the first variable image in accordance with a position of the waveform segment along a time axis transverse to the first waveform timeline and the second waveform timeline, the next non-periodic triggering event occurring a non-zero elapsed time period after the first non-periodic triggering event, the second waveform timeline being substantially parallel to the first waveform timeline;
- and
- offsetting the next decayed segment vertically and horizontally from the first decayed segment by an amount corresponding to the elapsed time period.
