Patent number: 9772353Abstract: Aspects of the invention include an equivalent-time sampling oscilloscope that receives a carrier signal, the carrier signal after it has been modulated with a repeating data pattern, and a pattern trigger signal that is synchronous with the data pattern. The carrier signal and the modulation are asynchronous, that is, they are not phase-locked in any way. The oscilloscope simultaneously samples the modulated carrier signal and quadrature phases of the unmodulated carrier signal at a plurality of timebase delays relative to the pattern trigger signal, and a plurality of times at each timebase delay. After collecting this information, the oscilloscope uses the quadrature samples to calculate phases of the unmodulated carrier signal that correspond to the samples of the modulated carrier signal.Type: GrantFiled: October 4, 2013Date of Patent: September 26, 2017Assignee: Tektronix, Inc.Inventors: Michael A. Nelson, John E. Carlson

Patent number: 7522661Abstract: A method of producing of a two-dimensional probability density function eye diagram and Bit Error Rate eye arrays generates a two-dimensional PDF array of a correlated waveform record of a data pattern under test which is convolved with a two-dimensional probability density function (PDF) array of the uncorrelated jitter and noise in the data pattern under test. The resulting aggregate two dimensional PDF array of the correlated waveform record pattern with uncorrelated jitter and noise is divided into unit intervals and the unit intervals are summed to generated a two-dimensional PDF eye diagram array. The two-dimensional PDF eye diagram is processed to generate a two-dimensional Bit Error Rate eye array.Type: GrantFiled: July 25, 2005Date of Patent: April 21, 2009Assignee: Tektronix, Inc.Inventors: Michael A.

Patent number: 7333489Abstract: A system and method for storing header information in parallel with corresponding frames of data, wherein the frames of data are stored in a first-in-first-out buffer and wherein the header information is accessed to make routing decisions for the frames of data while avoiding having to read the frames out of the buffer. In one embodiment, this buffer system is implemented in a port of a network switch. Receive logic in the port stores frames of data in the storage elements of a FIFO buffer and concurrently snoops on the frame data to obtain header information. The header information is stored in a buffer separate from the FIFO that stores the frames. The header information can be read from the header buffer rather than the frame buffer. A routing decision for each frame can be made before a previous frame is completely read out of the frame FIFO, hence before the corresponding frame is ready to be transmitted.Type: GrantFiled: October 24, 2000Date of Patent: February 19, 2008Assignee: Crossroads Systems, Inc.Inventors: Michael A.

Patent number: 6977897Abstract: A system and method for compensating for differences between a recovered receive clock and an internal transmit clock in an elastic buffer and thereby preventing corruption of data. In one embodiment, the system comprises a circularly accessed buffer coupled to read and write logic. The read and write logic read and write to locations within the circular buffer as indicated by respective read and write pointers. The system further comprises control logic which compares the pointers to determine whether the buffer is approaching an underflow or overflow condition and adds or deletes fill words between frames of data to compensate for the underflow or overflow condition. In one embodiment, the system includes fill word logic which is configured to add a fill word bit to each received word and to set or clear the fill word bit to indicate whether or not the corresponding word is a fill word.Type: GrantFiled: October 24, 2000Date of Patent: December 20, 2005Assignee: Crossroads Systems, Inc.Inventors: Michael A.

Patent number: 6927511Abstract: A generator incorporating a double sided fan operable to generate dual, spaced apart, simultaneous cooling airflows within the generator to more efficiently cool internal components located on opposite sides of the fan. The double sided fan generates a first cooling airflow into a permanent magnet generator (PMG) assembly and a second cooling airflow through an electronics assembly. The first cooling airflow cools a stator disposed within the PMG assembly, while the second cooling airflow cools a plurality of circuit boards disposed within the electronics assembly. The fan exhausts both cooling airflows radially outwardly.Type: GrantFiled: June 16, 2004Date of Patent: August 9, 2005Assignee: Black & Decker Inc.Inventors: Aris C. Cleanthous, Michael A.
