Abstract:
1. A method of identifying and recalling into an oscillographic display an arbitrary and operator selected portion of a waveform having digital values stored in a memory as an ordered sequence of values, the method comprising the steps of: (a) operator selection of an arbitrary waveform portion of interest by specifying a collection of parameters including values for horizontal position and horizontal scaling that determine which digital values are used to create waveform images in the display, the arbitrary waveform portion selected by the operator being less than the entire waveform; (b) associating an ordinal label with the collection of horizontal position and horizontal scaling parameters specified in step (a); (c) storing in a memory the association of the ordinal label of step (b) with the collection of horizontal position and horizontal scaling parameters specified in step (a); (d) subsequent to step (c), displaying a waveform image different from the arbitrary waveform portion of interest specified in step (a); (e) subsequent to steps (a)–(d), operator selection of an ordinal label from a menu showing at least one ordinal label that has been associated in step (b) and whose association was stored in step (c); and (f) in response to step (e), displaying the operator selected and arbitrary waveform portion specified by the collection of horizontal position and horizontal scaling parameters in step (a) and associated with the ordinal label of step (b) by re-invoking the values of the horizontal position and horizontal scaling parameters in the collection associated with the ordinal label chosen from the menu in step (e).
