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 ...

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from ...

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, ...

Tests show signal is compatible both with current NextGen demodulation devices and analog FM tuners When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

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 ...

To allow for coherent demodulation at the user equipment, reference symbols (or pilot symbols) are inserted in the OFDM time-frequency grid to allow for channel estimation. Downlink reference symbols ...

The Aeroflex CS9000 Broadband Signal System (BSS) test system has been developed for signal generation and recording for simulation and analysis of advanced communications signals in extreme ...
