Abstract: A test and measurement instrument includes an array of data pipes, in which each of the array of data pipes further includes an input coupled to an output of an interleaved Analog-to-Digital Converter (ADC), a hysteresis processor coupled to the input to receive a present pipe data value, and coupled to another hysteresis processor in the array of data pipes to receive a previous data value and a previous data direction, the hysteresis processor structured to perform a comparison of the present pipe data value to the previous data value to determine whether a magnitude of a difference between the present pipe data value and the previous data value exceeds a hysteresis value, and a pipeline trigger comparator. Methods are also described.

Abstract: A test and measurement instrument has a user interface configured to allow a user to provide one or more user inputs, a display to display results to the user, a memory, one or more processors configured to execute code to cause the one or more processors to receive a waveform array containing waveforms resulting from sweeping one or more parameters from a set of parameters, recover a clock signal from the waveform array, generate a waveform image for each waveform, render the waveform images into video frames to produce an image array of the video frames, select at least some of the video frames to form a video sequence, and play the video sequence on a display. A method of animating waveform data includes receiving a waveform array containing waveforms resulting from sweeping one or more parameters from a set of parameters, recovering a clock signal from the waveforms, generating a waveform image from each of the waveforms, rendering the waveform images into video frames to produce an image array of the video frames, selecting at least some of the video frames to play as a video sequence, and playing the video sequence on a display.

Abstract: An information processing apparatus includes an extraction unit, a determination unit, a display control unit, and a display unit. The extraction unit is configured to extract, by predetermined pattern matching, candidate peaks in a certain arbitrary period of time from among at least one or more pieces of waveform data. The determination unit is configured to determine, from among the candidate peaks of the waveform data, a single peak based on a score related to the pattern matching. The display control unit is configured to output display information for displaying a position of the peak. The display unit is configured to display the display information.

Abstract: Methods and measurements systems are disclosed relating to use of a soft front panel (SFP) to display results of measurement functions. A measurement device may concurrently perform two or more measurement functions to produce two or more respective signal measurements, wherein each measurement function comprises an acquisition function and a processing function. A computer may be configured to display information on a soft front panel on the display device corresponding to two or more of the signal measurements. The computer may receive, from a user, a selection of an update option, wherein the update option indicates a trigger that causes the displayed information to update. Responsive to receiving an indication that the trigger has occurred, the computer may update the displayed information on the soft front panel.

Abstract: A measurement system is provided that performs a trigger data acquisition algorithm. When the measurement system performs the trigger event data acquisition algorithm, it causes a preselected number of digital data samples acquired during a first time window that includes a trigger event and during a second time window that is specified by the user and that is subsequent in time to the first time window to be stored in memory. Digital data samples acquired after the end of the first time window and before the beginning of the second time window are not stored in memory. By not storing digital data samples acquired after the end of the first time window and before the beginning of the second time window, the possibility of overwriting samples that surround the trigger event is prevented and the memory is used very efficiently.

Abstract: A method for distinguishing between individual human subjects using plethysmographic waveforms. In one embodiment, the method comprises the steps of: receiving a plurality of plethysmographic signals from different individuals; normalizing the signals to the same period length and mean; changing the basis of each of the plurality of signals to obtain its basis vectors and coefficients; reducing the number of coefficients for each signal in the plurality of signals; and calculating the covariance matrix and mean for each individual's set of normalized and dimensionally-reduced plethysmograph waveforms. In another embodiment, the method further comprises the step of taking the Mahalanobis distance between each new plethysmograph waveform that has also been normalized and dimensionally reduced and the stored models of all individuals. In yet another embodiment, the method further comprises the step of finding the index of the stored model with the minimum Mahalanobis distance.

Abstract: A system and method for calculating a bit error rate for a mask is described. For each time during the time duration of the mask, the minimum and maximum voltages of the mask at that time are determined. The maximum bit error rate can be calculated for each time by integrating between those voltages. The maximum bit error rate for all times during the time duration of the mask can be selected as the maximum bit error rate for the mask.

Abstract: A test and measurement instrument processes digital data that represents an input signal to produce a target image, and then uses a computer vision technique to recognize a signal depicted within the target image. In some embodiments, the location of the signal within the target image is identified on a display device. In other embodiments, the location of the signal within the target image is used to perform a measurement. In other embodiments, when the signal is recognized, a trigger signal is generated that causes digital data that represents the input signal to be stored in a memory.
