Patent number: 9727228Abstract: 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.Type: GrantFiled: February 22, 2013Date of Patent: August 8, 2017Assignee: Keysight Technologies, Inc.Inventors: Douglas James Beck, Daniel P.

Patent number: 6344844Abstract: The present invention is generally directed to a digital oscilloscope and associated method that provides a peak detect mode of operation that not only accurately displays peak information, but also reflects the significance of peak information, without distorting a statistical view of the signal. In this regard, and in accordance with one aspect of the invention, the oscilloscope includes an analog to digital (A/D) converter configured to periodically sample an input signal and convert the periodic samples into a train of digital data. A circuit is disposed at the output of the A/D converter and is configured to evaluate the train of digital data over a first predetermined period of time and detect a minimum value and a maximum value during the first period of time. A mechanism is configured to evaluate the minimum and maximum values and determine a significance measure of the minimum value and the maximum values.Type: GrantFiled: August 21, 1998Date of Patent: February 5, 2002Assignee: Agilent Technologies, Inc.Inventors: Daniel P.

Patent number: 6329936Abstract: Spurious artifacts in intensity emulation caused by measurement non-linearities within a statistically created raster display are reduced or eliminated by first characterizing the non-linearities. Armed with this information the collection of code values in an aperture can be inspected to notice which code values are occurring. M-many out of every n-many instances of a fat code can be replaced by an adjacent code, with a frequency of replacement that is selected to counteract the fatness. In principle, the replacement mechanism could be sensitive to prior events and propagate or distribute corrections across a family of abnormal codes. The idea is to statistically adjust the collection of codes to be closer to what it would be if there were no non-linearities. Different non-linearities may benefit from different strategies for replacement. Certain safeguards may be desirable to prevent making the problem worse rather than better.Type: GrantFiled: October 30, 1998Date of Patent: December 11, 2001Assignee: Agilent Technologies Inc.Inventor: Daniel P.

Patent number: 6246389Abstract: A method of determining an intensity value for a pixel in a display for displaying digitized waveforms. The intensity values simulate an analog display so that intensity at high slew rates about a point is lower than intensity at low slew rates about a point. Intensity may be computed as a function of slew rate. Alternatively, for speed, the absolute difference between waveform magnitudes at consecutive samples is used as an index into a pre-computed table of intensity values. As a result, for each sample, only a subtraction and a table look-up are needed to provide intensity variation. In an alternative embodiment, intensity values are higher at higher slew rates to accentuate rising and falling edges of digital waveforms.Type: GrantFiled: June 3, 1997Date of Patent: June 12, 2001Assignee: Agilent Technologies, Inc.Inventor: Daniel P.

Patent number: 6188966Abstract: A method of connecting displayed samples of a signal, where the samples are obtained by sequential or random repetitive sampling. Three example embodiments are presented. In a first embodiment, the system decides whether or not to connect to the next consecutive sample, based on the outcome of comparison of the magnitude of the slope to a slew rate threshold. In the second embodiment, the system looks ahead (or behind) up to M samples to see if any samples represent valid slew rates, and connects to the first sample representing a valid slew rate. In the third embodiment, the system looks ahead (or behind) M samples and connects to the sample in the next M samples that represents the smallest valid slew rate. In each embodiment, if no sample represents a valid slew rate, no connection is drawn. In the second and third example embodiments, by looking ahead (or behind) M samples, the system can potentially resolve a waveform with up to M phases and can accommodate trigger placement uncertainty.Type: GrantFiled: February 10, 1998Date of Patent: February 13, 2001Assignee: Agilent TechnologiesInventors: Daniel P.

Patent number: 5898420Abstract: A signal acquisition and display system that always provides the maximum possible display bandwidth that can be provided by the system without causing the display update rate to be reduced below the maximum determined by the acquisition time window. The optimization does not require analysis of a separate acquisition and does not require a repetitive waveform. The acquisition system alternates between two sections of memory, so that the minimum display update time is the longer of the acquisition time window or the display plot time. The display record length is variable. The display record length is controlled to make the display plot time always equal to or slightly less than the acquisition time window. Therefore, display bandwidth is always at the maximum possible given the acquisition time window and the maximum display update rate determined by the acquisition time window. Display record lengths may be very long compared to typical previous instruments.Type: GrantFiled: August 13, 1997Date of Patent: April 27, 1999Assignee: Hewlett-Packard CompanyInventor: Daniel P.

Patent number: 5282266Abstract: A system that uses two character positions on a display area of an oscilloscope to indicate the progress being made toward achieving a target number of waveform acquisitions. The system displays the percentage of waveform acquisitions taken within this two character percentage display area by first displaying two symbols as white dots on a dark background. As the percentage of waveform acquisitions taken increases, the dots within the symbols are inverted starting at the bottom of the display area and progressing toward the top. When the target number of waveform acquisitions have been taken, all the dots within the symbols are inverted to display dark on white. As the percentage increases, the dots forming the first character of the display are inverted prior to the dots forming the second character. Therefore, higher resolution of the display is obtained.Type: GrantFiled: January 31, 1991Date of Patent: January 25, 1994Assignee: Hewlett-Packard CompanyInventors: Mark P. Schnaible, Daniel P. Timm
