Abstract:
An oscilloscope including an input port for receiving training data including waveforms and corresponding known classifications and a processor for training a plurality of classifiers on the training data. Training includes iteratively applying each classifier to each waveform of the training data to obtain corresponding predicted waveform classifications and comparing the predicted waveform classifications with the known classifications. Classifiers are corrected when predicted waveform classifications does not match the known classifications. Models for each classification are constructed with suggested measurements or actions. Subsequently, live waveform data is captured by the oscilloscope and the classifiers are applied to the live data. When a confidence value for a single classification exceeds a threshold, the waveform data is classified, and suggested measurements or actions are implemented in the oscilloscope based on the classification.
Abstract:
A method in an electronic device that may include determining, with a processor, a quantity of group markers in a data set, and determining, with the processor and based on the quantity of group markers, a suggested view from a plurality of available views, each view in the plurality of available views diagrammatically depicting at least a portion of the data set. Also, a processor-implemented method of navigating between portions of a data set may include displaying, on a touchscreen display, a diagrammatical depiction of a first portion of the data set; detecting a continuous arc gesture at the touchscreen display; determining a direction of the arc gesture; selecting a second portion of the data set based on the determined direction of the arc gesture; and displaying a diagrammatical depiction of the second portion of the data set.
Abstract:
An apparatus and method corrects for zero ampere level current fluctuations in a current signal. First and second acquisition circuitry generate respective current and voltage data samples of the current signal. Current fluctuation data samples representative of zero ampere level deviations of the current signal are extracted corresponding to Off-periods of the current signal. The current fluctuation data samples of the Off-periods are interpolated to generate current fluctuation data samples representative of zero ampere level deviations of the On-periods of the current signal. The Off-period and On-period current fluctuation data samples are subtracted from the current data samples of the current signal to generate corrected zero ampere level current data samples.

Abstract:
A method can include receiving an input signal having multiple signal edges, performing an initial scan of the input signal to identify peaks corresponding to the signal edges, and determining whether each peak is a Uniformly Synchronous (US) edge or a Quasi-Synchronous (QS) edge. The method can also include generating a final waveform and displaying the final waveform on a display device.

Abstract:
Embodiments of the invention provide a system and method to measure and represent the measured value of a limit in terms of another measurement, such as clock values or cycles of the system. The system can include, for example, a test and measurement instrument such as an oscilloscope. In another embodiment of the present invention, slew rate de-rated values may be automatically determined through the use of configurable lookup tables.
Abstract:
A digital oscilloscope in which the acquisition/data accumulation is decoupled from the display of the accumulated data in order to increase the speed at which new data may be accumulated and displayed. The invention also provides for variable persistence in the accumulated data so that the displayed image shows the changes in the sampled event over time. The decay, however, is proportional to population for each amplitude/time combination in the data. This maintains the statistical integrity of the data. Further, the data from each channel is assigned a different color and different populations within the channel's data is assigned a different shade of the color. These shades are dynamically updated as data from new acquisitions are accumulated. In order to highlight the population distributions in the rare events, population saturation levels may be specified.
