New Method Reveals All You Need To Know About 'Waveforms' Oct 13, 2009
The new method improves accuracy in calibrations of oscilloscopes, common test instruments that measure voltage in communications and electronics devices, and potentially could boost performance and save money in other fields ranging from medical testing to structural analysis to remote sensing ... The mathematics-intensive method is laborious and currently is performed only at NIST (which has more than 750 oscilloscopes), but the developers plan to write a software program that will automate...

Carleen Hutchins; devised new system to make violins, 98 Aug 15, 2009
Before long, the basement of Mrs. Hutchins s home in Montclair was awash in oscilloscopes. With several colleagues, she founded the Catgut Acoustical Society, dedicated to the study of musical acoustics, in 1963. (Boston Globe)
NPL helps develop unique new calibration tool for radio frequencies Jun 23, 2009
To achieve this, NPL's Matthew Harper spent two weeks on secondment to Fluke in Norwich investigating the application of a new technique, in-phase quadrature (IQ), developed at NPL. By exploiting a timing characteristic in the operation of certain sampling oscilloscopes, IQ enables NPL to correct for timebase errors in the oscilloscope and greatly enhance the accuracy of measured waveforms. Matthew succeeded in establishing that this technique had the potential to provide AM traceability at the... (EurekAlert! -- Business News)
Healing wounds with lasers, vehicles that drive themselves, other cutting-edge optics May 27, 2009
For performing high-end physics, ordinary oscilloscopes and televisions aren't fast enough, and the deflection of a beam used to display an image or a short-lived signal requires a different technology, which sometimes goes by the name "streak camera." Because the electrons comprising the beam are charged particles, the signals they carry suffer unavoidable blurring where the signal strength is strongest, thereby limiting the useful dynamic range. John Heebner and colleagues at Lawrence... (EurekAlert!)
Xilinx Starts Shipments of Virtex-6 FPGAs Apr 1, 2009
"Having early access to technology like the new Xilinx Virtex-6 FPGAs, with their high-performance and low power consumption, is critical for Agilent to deliver next generation Oscilloscopes that exceed our customers' needs," said Brad Doerr, R&D Manager for Agilent's High Performance Oscilloscopes Group. "Agilent's early adoption of leading edge technology is one of the reasons we have been the fastest growing oscilloscope manufacturer since 1997.". (PR Newswire)
Thomas Goldsmith, 99; helped invent TV Mar 26, 2009
"DuMont and Goldsmith helped pioneer turning oscilloscopes into full television displays," Alexander Magoun, the author of "Television: The Life Story of a Technology," said ... Cathode ray tubes had already been used for nearly 30 years by scientists and engineers for oscilloscopes, devices that create a graphic display of electronic signals. (Boston Globe)
Saugus engineering student does his Rube Goldberg Thing Mar 20, 2009
M5 (short for Marcus Hall, Room 5) consists of 13 rooms chockablock with circuits, chips, parts, voltmeters, power supplies, oscilloscopes, audio/video equipment, microcontrollers and many other things near and dear to the hearts of engineers. It s a place, as one student jokes, where electrical and computer engineering students can do their Rube Goldberg thing, referring to the Pulitzer-Prize-winning cartoonist who drew fantastical, imaginary machines.

In Oregon, Tek cuts paychecks, others cut jobs Feb 8, 2009
Tektronix makes oscilloscopes and other devices used to measure the output and performance of electronic devices. Pay cuts are starting to become popular across the United States, said New York Times columnist Paul Krugman, who was in Portland on Thursday to speak at the World Affairs Council of Oregon.
