Abstract: Traces are placed in a plurality of windows. Each trace is weighted based on a plurality of attributes of the trace. The traces are sorted based on the weighting. Boundaries between traces are assigned based on transitions in attributes. The boundaries function to divide the traces into windows.

Abstract: An electronic instrument includes instrument hardware, core software, and the ability to support custom data processing libraries, separate from the core software. The instrument hardware acquires unprocessed measured data. The core software includes standard measurement objects and standard algorithms. The standard measurement objects produce analysis results of the unprocessed measured data. The standard algorithms are used by the standard measurement objects to aid in production of analysis results of the unprocessed measured data. Custom libraries as supported by the core software include custom measurement objects and custom algorithms. The custom measurement objects produce analysis results of the unprocessed measured data. The custom algorithms are used by the custom measurement objects to aid in production of analysis results of the unprocessed measured data.

Abstract: An electronic instrument includes instrument hardware. A data acquisition engine schedules time sharing of the instrument hardware. Channel objects act each as a client of the data acquisition engine. The channel objects each included a channel buffer that contains data obtained from the instrument hardware. Measurement objects are each a client of one of the plurality of channel objects. Each measurement object processes data obtained from a channel buffer of a channel object to which the measurement object is a client. Display window objects are each a client of at least one of the plurality of measurement objects, each display window object displaying data processed by any measurement object to which the display window object is a client. Memory within the electronic instrument is allocated among object types to accommodate a user specified mix of object types.

Abstract: An interface for an electronic device includes a plurality of function keys. Each function key has a distinct color different from other function keys in the plurality of function keys. The electronic instrument also includes a display. The display displays a plurality of soft key labels. Each soft key label is associated with and has a same color as one function key from the plurality of function keys. Coloring indicates to a viewer of the display associations between soft key labels and function keys.
