RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

Time Spectrum Analyzer, built on the newly upgraded UltraReal platform. This innovative instrument seamlessly integrates high ...

Saelig has introduced the Rigol RSA6000 Series Real-Time Spectrum Analyzers in 8/14/26.5GHz versions, based on the UltraReal platform.

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

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 ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240105, discusses a high-resolution tumor marker detection based on microwave photonics demodulated dual wavelength fiber laser ...

Lock-in amplifiers let you measure very small signals that would otherwise get lost in the noise of even the best available amplifiers. Originally analog circuits, lock-in amplifiers have evolved into ...
