摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method for operating a data processing system having a touch enabled display screen that displays a plurality of waveforms to alter the display of one of the waveforms without altering the display of the remaining waveforms is disclosed. The method includes determining a selected waveform in response to a user touching the display screen in a first location thereby defining a touch area that determines the selected waveform. An operation that is to be performed on the selected waveform is then defined by a gesture on the screen. The selected waveform is determined by a touch area that is defined by the user touching the screen. If more than one waveform is defined by the touch area, the possible waveforms are sequentially selected until the correct one is presented to the user in response to the user repeating the touching that defines the touch area.
