New Unit Improves Resolution by 2000 Times, Enabling Engineers to View RF Signal Instabilities and Transients that They Never Knew Existed BEAVERTON, Ore.—Tektronix, Inc., a leading worldwide provider ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of ...

Magnacom emerged from stealth mode claiming it has a new twist on digital modulation technology that provides big gains for any wired or wireless network. The company will license its technology on ...

Wireless local-area networks (WLANs) can now take advantage of the Advantest R3681 test tool for analyzing spectrum and broadband modulation. It features an average noise level of −156 dBm/Hz, 26-dBm ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

Optical modulators can have high modulation speed and broad bandwidth, while being compact. However, these optical modulators usually work for low-intensity light beams. Here we present an ultrafast, ...

Analog Devices, Inc., which recently acquired Linear Technology Corporation, has announced the LTC7124, a high efficiency, 4MHz synchronous dual output buck regulator that incorporates a constant ...
