The method of processing waveform data from one or more channels using a test and measurement instrument, such as an oscilloscope, is described in which waveform data is collected from a DUT; defining a context is defined by instructing the instrument to obtain the focus of each waveform datum having a first user-defined attribute; defining a selection criteria by instructing the instrument to obtain the focus of each waveform datum having both a first user-defined attribute and a second user-defined attribute; and defining an action by instructing the instrument to perform an operation responsive to finding at least one waveform datum having both the first user-defined attribute and the second user-defined attribute.

Method of processing waveform data from one or more channels using a test and measurement instrument

The apparatus for a test and measurement instrument consists of multiple integrated circuits with each integrated circuit being connected to its own memory controller. At least one of the integrated circuits is a specialized integrated circuit, which may be a graphics processing unit, a digital signal processor, or a field-programmable gate array. Each memory controller is connected to its own memory. The integrated circuits are connected in a circular arrangement by multiple high-speed interconnects. A bridge is connected to at least the first and last integrated circuits. A system bus connects the bridge to an acquisition module. The acquisition module has a signal bus interface with the system bus being connected to the acquisition module and having its own acquisition hardware. The acquisition hardware is a direct memory access machine that can transfer data to any portion of the memory. There is a signal source connected to the signal bus interface.

Apparatus and method for a test and measurement instrument

A method of indicating and manipulating a zoom region of a waveform being displayed includes a zoom region indicator. The zoom region indicator has an associated marker that spans the zoom region but is never less than a minimum span to allow ease of identifying or locating the zoom region on the displayed waveform. Manipulating the associated marker with a pointer device causes the zoom region to move accordingly along the displayed waveform. The portion of the displayed waveform that is within the zoom region is displayed as a zoomed waveform on the display.
