Keysight introduces RF signal analyzers for faster wireless design and validation with wider bandwidth and more accurate RF ...

Scientists have demonstrated a new fiber-optic sensing method that detects strain and displacement by reading interference patterns directly in the electrical spectrum of a photodetected signal. The ...

Old modems have a lot more going for them than it might seem ...

A fab lab, short for fabrication laboratory, is a digital fabrication workspace rather than a traditional hand-tool workshop.

Abstract: We present an architecture for millimeter-wave spectrum analyzers with Hz resolution and precision based on heterodyne down-conversion using ErAs:InGaAs photoconductive mixers driven by a ...

The safety and sterility of injectable pharmaceuticals, vaccines, and implantable medical devices depend fundamentally on the detection of bacterial endotoxins. Even in picogram quantities, these ...

China's Tianwen-2 spacecraft arrived at near-Earth asteroid 469219 Kamo'oalewa on July 6, 2026, completing a 400-day, 1-billion-kilometer voyage to one of the strangest objects in Earth's neighborhood ...

Abstract: This paper proposes a parametric method of frequency-dependent I/Q imbalance compensation for wideband quadrature modulators using the spectrum measurement of a radio frequency (RF) signal ...

hackrf_sweep backend enables wideband spectrum monitoring by rapidly retuning the radio without requiring individual tuning requests from the host computer. This allows unprecedented sweep rate of 8 ...
