Publication number: 20040153266Abstract: The time needed to perform an eye diagram measurement is minimized by initially randomly investigating the (X, Y)i that lie on a “starting” line crossing the sample space and expected to intersect any eye diagram. This finds a location on the eye diagram. Then the eye diagram is traversed as it is discovered by investigating nearest neighbors of locations found to belong to the eye diagram. Two arrays E and L of bits are established. The bits of E represent “eligible” (X, Y)i, while those of L represent “likely” (X, Y)i. At the very start of the measurement all bits in the eligible array E are set and all those in the likely array L are cleared, except that the starting line is established by setting in L and clearing in E locations for the corresponding (X, Y)i. Thereafter, locations in L that have Is are measured in a randomly selected order.Type: ApplicationFiled: January 31, 2003Publication date: August 5, 2004Inventor: Richard A. Nygaard

Patent number: 6396517Abstract: An integrated trigger function display system and methodology for trigger definition development in a signal measurement system having a graphical user interface. The system contemporaneously displays one or more trigger function names and an associated trigger function descriptor describing a trigger function identified by the associated trigger function name. The trigger name is displayed in a trigger name display region of a display window that concurrently displays a plurality of trigger function names. The descriptor is displayed in a trigger descriptor region of the display window so as to be visually-associated by the operator. A trigger definition is comprised of one or more trigger functions. Each trigger function is a graphical representation of an one or more underlying trigger primitives. A trigger primitive is a computer program statement that is translated into a form suitable for controlling the signal measurement system.Type: GrantFiled: March 1, 1999Date of Patent: May 28, 2002Assignee: Agilent Technologies, Inc.Inventors: Douglas James Beck, Clarence Keith Griggs, Jeffrey Erickson Roeca, Jeffrey John Haeffele, Mason Bradfield Samuels

Publication number: 20010001137Abstract: A signal scaling system and methodology for use in a signal measurement system such as a digital or analog oscilloscope, logic analyzer, network analyzer, spectrum analyzer or waveform generator that has a graphical user interface which controls a waveform display region on a display device. The signal scaling system determines one or more displayed waveform scaling parameters to cause portions of selected displayed waveforms appearing within a rescaling rectangle to occupy a predetermined portion of the waveform display region other than the resealing rectangle. For each of the selected displayed waveforms, the scaling parameters may include horizontal scaling, horizontal offset, vertical scaling and vertical offset. Preferably, the predetermined portion of the waveform display region comprises the entire waveform display region and the selected displayed waveforms include all waveforms at least partially within the resealing rectangle.Type: ApplicationFiled: December 19, 2000Publication date: May 10, 2001Inventor: Jay A.

Patent number: 6195617Abstract: A method for presenting information and a digital storage oscilloscope are disclosed in which primary measurements of a signal are performed and displayed. Parameters are also derived for the signal based upon the primary measurement data. These derived parameters are then also displayed as a function of time on the display, preferably with a common time axis. This enables the oscilloscope operator to correlate features found by reference to the derived parameters directly to the primary measurements of the signal. Moreover, since the data from the primary measurements are stored in the oscilloscope, multi parameter calculation and parameter recalculation can be performed.Type: GrantFiled: March 9, 1998Date of Patent: February 27, 2001Assignee: LeCroy, S.A.Inventor: Martin T.

Patent number: 6104986Abstract: A method and apparatus for a phase shifter includes a controller controlling a voltage controlled phase shifting circuit for shifting the phase of a high frequency input signal. The phase shifting circuit includes microstrip elements arranged in a 3 dB hybrid structure, and also includes first and second reverse-biased diodes electrically connected to the microstrip elements and operating as varactors. The controller drives a D/A converter to control the bias voltage of the phase shifting circuit and thereby to adjust the phase shift of a high frequency output signal relative to the high frequency input signal.Type: GrantFiled: April 2, 1998Date of Patent: August 15, 2000Assignee: AmerAmp, LCInventor: Augusto Arevalo

Patent number: 6088029Abstract: A real-time data display in a control window of a measurement instrument receives real-time data corresponding to an application, wherein the real-time data is to be displayed to a user. A control window is also displayed, including one or more user-selectable options within the control window and at least a portion of the real-time data within a portion of the control window. A user selection of an option to alter a display of the real-time data is then received, and the real-time data being displayed is altered within the portion of the control window in accordance with the user-selected option.Type: GrantFiled: June 26, 1998Date of Patent: July 11, 2000Assignee: Tektronix, Inc.Inventors: Kelcie Guiberson, Wendell W.
