Abstract: A method, system, and program for providing runtime graph parameters and conditional components for data flow graphs. Runtime parameters allow an application builder to defer the value of a parameter setting to runtime. The values of runtime parameters may be supplied by the end user or be derived from a combination of other runtime parameters or objects stored in an object repository. A developer may specify a prompt for each parameter and the conditions for displaying the prompt, which are used to determine a graphical user interface control for receiving the parameter value. A conditional components mechanism permits changes to a graph structure based on parameter values and computed metadata. Each component of a graph has a condition which controls whether or not that component will appear in the graph at runtime. The condition can be computed directly or indirectly through runtime parameters.

Abstract: A video field rate persistence is provided for a video waveform display where multiple video components are displayed simultaneously, one component being updated per field interval. A persistence count is assigned to each pixel in a circular field buffer which is divided equally into a number of sub-buffers representing a portion of a display raster, one for each component. The persistence count is updated for each update of the circular field buffer with the pixel values being maintained until the persistence count equals a maximum value, at which point the pixel values for that component are updated with new pixel values. In this manner the display pixels for each component are updated every X video fields and are maintained at their prior values between updates to provide a flicker free display without temporal separation.

Abstract: A method of data acquisition for a digital instrument having a bandwidth. The method includes receiving a signal and associated trigger. Using that trigger, a plurality of signal values is sampled at multiple time intervals to create an acquisition record representing a continuous fractional segment of the signal. The plurality of samples meets the Nyquist requirement for the bandwidth but is in error according to at least one known error mechanism. The acquisition record is then processed with DSP techniques to produce a compensated acquisition record corrected for the at least one known error mechanism. Each associated compensated acquisition record is incorporated into a result acquisition record as a segment thereof corresponding to a continuous fractional segment of the signal whose signal values were sampled in an associated instance. An additional signal and additional associated trigger are received. The above steps are then repeated for the additional signal and additional associated trigger.

Then, a property specified for the waveform is extracted from the digital waveform data in each of the time segments, and a value expressing the specified property in the time segment is obtained on the basis of the extracted property. Further, a waveform display portion in each of the time segments displayed on the screen on the basis of the compressed display data in each of the time segments is displayed in a state wherein the obtained value expressing the property is reflected on the waveform display portion.

Abstract: Apparatus in accordance with the subject invention maintains an exponentially decayed histogram of the counts of new pixels for each active channel, together with a running count of time and number of acquisitions. At regular intervals determined by a maximum time or by a minimum number of acquisitions it computes a new threshold for each active channel. This threshold will theoretically produce “N” nominally unusual waveforms per second where N is defined by a user “sensitivity” control. The raw histogram is smoothed to provide a stable “tail” of small probabilities. Once a threshold has been determined, subsequent waveforms with more than this number of new pixels are re-examined to determine the number of “really new” pixels. “Really new” pixels are defined as those that are not adjacent to pixels remaining from earlier acquisitions. Only those waveforms that have more “really new” pixels than a specified fraction of the basic threshold are reported as anomalies.

For sequential playback of the stored metric values, both a starting and an ending position can be determined. The data can be sequentially played back beginning at the starting position and terminating at the ending position. During playback, a list can be provided for selecting those metrics and entities of the data space that are to be displayed on the graphical display.

Abstract: A digital oscilloscope assists in the process of identifying, cataloging and restoring views of interest within a stored trace acquisition by implementing the notion of bookmarks. In response to a command to establish a bookmark, the scope takes note of selected display control parameters, such as the location of the view in the overall acquired trace and horizontal time per division, and stores that as a named bookmark. The scope accepts from the operator a comment associated with each bookmark. Another command lists defined bookmarks and causes the scope to re-institute the view and parameters associated with a specified bookmark. There is a mechanism for editing the descriptors or parameters that are defined by a bookmark.

Abstract: An oscilloscope that is capable of displaying simultaneously multiple waveforms representing time evolution of a signal during respective acquisition intervals acquires waveform data using a first set of acquisition parameters and generates a display based on that waveform data. If the display includes a waveform that is visually distinct from other displayed waveforms, the user selects a feature that distinguishes the visually distinct waveform from other displayed waveforms. The oscilloscope automatically derives updated acquisition parameters that discriminate between the selected feature and other features of the displayed waveforms. The oscilloscope then acquires waveform data using the updated acquisition parameters and generates a display based on that waveform data.

Abstract: Trial decimations are performed on an acquired waveform. Each trial produces a sequence of packets applied to a complexity detection circuit. Each packet contains a decimation value to be used in place of acquisition values to be suppressed along a decimation sample width. Each packet also includes the maximum and minimum values that occurred within the associated decimation sample. A plurality of counters record for a trial decimation the number of instances when the differences in waveform extremes exceed a corresponding plurality of selected thresholds. Complexity introduced by decimation will tend to produce waveforms having larger voltage excursions over the region of suppressed acquisition samples. The data in the counters is processed to produce a suite of histograms examined to select a decimation factor that does not introduce significant additional complexity.

Abstract: An improved apparatus and method for tuning a device under test uses a spider diagram-like chart that provides the operator with visual cues as to the tuning status of a device under test (DUT). The spider diagram may be displayed on a graphical user interface (GUI), along with various adjustment points or potentiometers.

When a measured parameter value is at the center of its allowable range, the vertex of the angle corresponding to that measurement lies near the center of the unit circle. When a measured parameter is at its upper or lower bound, the vertex lies on the unit circle.

Abstract: A telecom mask testing zoom function draws mask. pixels into a raster memory. In this way, the mask is treated as a waveform. Comparison of the mask pixels and waveform pixels to detect collision between a waveform pixel and a mask pixel (i.e., a mask violation) is performed substantially in real time, as the pixels are being composited into the raster memory by the rasterizer. The mask is scalable and repositionable by the rasterizer under control of a controller, because it is treated as a waveform. The mask is lockable to the waveform because both are stored in pixel form in raster memory by the rasterizer under control of the controller.
