April 29, 2002[Technology Report] FFT Brings Spectrum Analysis To The Scope
Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no access to a spectrum analyzer, yet occasionally...
April 29, 2002[Technology Report] Spectrum Analyzers Answer Call For Speed
The easiest way to envision a spectrum analyzer is to begin with an oscilloscope that plots magnitude versus time. Then swap frequency for time—and voilà—a spectrum analyzer! A gross simplification perhaps, but no one...
April 01, 2002[Technology Report] Shopping For A Logic Analyzer
How many signals do you need to capture and analyze? Be sure to take into account all of the buses and signals that you must acquire simultaneously. A logic analyzer's channel count maps directly on a one-for-one basis with the number of signals that...
April 01, 2002[Technology Report] Logic And Protocol Analyzers Acquire More Muscle
For designers of telecommunications and wireless products, the challenge is to choose an appropriate mix of instruments for analysis and debug, and the move is to logic and protocol analyzers. Fledgling digital system designs are still plagued by...
January 7, 2002[Technology Report] Test & Measurement: Oscilloscopes
Oscilloscopes Ramp Up WHEN I WAS IN HIGH SCHOOL, THE physics teacher brought out the Dumont oscilloscope whenever it came time to discuss electricity. I don't recall its model number, and the demise of Dumont is...
December 17, 2001[Technology Report] Next-Generation Products Going Display-Centric
When it comes to the notion of "embedded," the microprocessor may have to renounce its sovereignty and share its scepter with the flat-panel display. The reason is simply that embedded may soon connote displays as well as microprocessors. When a...
June 4, 2001[Forefront] TDR Detects Defects In BGA Packages
TDA Systems Inc. of Portland, Ore., is developing a time domain reflectometry (TDR) software prototype for detecting defects in ball-grid-array (BGA) IC packages. TDR measurement is recognized as an effective, nondestructive method for fault...
May 21, 2001[Forefront] Electronic Licensing Systems Thwart Piracy
The software market seems to be virtually bulletproof, invulnerable to the slackening in other sectors of the U.S. economy. Software sales are expected to surge from $200 billion in 2001 to $235 billion in 2002 (...
May 21, 2001[Design Application] OLEDs And CLCDs Each Seek Their Niche
OLEDs: Flat-panel displays made with the new organic light-emitting diode (OLED) technology consume roughly 75% less power than backlit LCDs. The OLED display is emissive, so it is sharp and highly viewable, even in bright sunlight. Perhaps...
