Have you ever looked at a spectrum analyzer display of a quadrature amplitude modulation (QAM) signal and wondered why its displayed amplitude doesn’t match its digital channel power? Consider an ...

Newswise — The analysis of light and its propagation in media is fundamental in our information society. Human eyes – which we use to perceive the world – are probably the most sophisticated yet ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...

Palo Alto, Calif.—Test-and-measurement supplier Agilent Technologies Inc. is rolling out a combination of products that tightly integrate digital signal capture of Agilent's logic analyzers with the ...
