Abstract
A test and measurement instrument includes an input for accepting an input signal from a Device Under Test (DUT), acquisition memory for storing a sampled waveform derived from the input signal, an output display, and one or more processors configured to accept a portion of the sampled waveform as a search portion, search the sampled waveform for portions similar to the search portion, and visually indicate, on the output display, portions of the sampled waveform that are similar to the search portion as matched portions. Methods of operation and description of storage media, the operation of which performs the above operations, are also described.
Claims20
A test and measurement instrument, comprising:
- an input for accepting an input signal from a Device Under Test (DUT);
- acquisition memory for storing a sampled waveform derived from the input signal;
- an output display;
- and
- one or more processors configured to:
- accept a portion of the sampled waveform as a search portion,
- search the sampled waveform for portions similar to the search portion, and
- visually indicate, on the output display, those portions of the sampled waveform that are similar to the search portion as matched portions.
A method of operation of a test and measurement instrument, comprising:
- searching a sampled waveform stored on the test and measurement instrument for portions similar to a selected portion of the sampled waveform;
- and
- visually indicating, on an output display, portions of the sampled waveform that are similar to the selected portion of the sampled waveform as matched portions.
A non-transitory computer-readable storage medium storing one or more instructions, which, when executed by one or more processors of a computing device, cause the computing device to:
- search a sampled waveform accessible by the computing device for portions similar to a selected portion of the sampled waveform;
- and
- visually indicate, on an output display, portions of the sampled waveform that are similar to the selected portion of the sampled waveform as matched portions.
