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 ...

Editor’s note: The following is an excerpt from an article that appears in the May edition of Broadcast Engineering magazine by John Morrow, CEO of Morrow Technologies and Debbie Mucciolo, project ...

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 ...

The preview of Edition 3 of CISPR 16-1-1—the international standard covering EMC (electromagnetic compliance)—is now available. If approved, the standard will allow engineers to make compliance ...

Measuring phase noise with a spectrum analyzer. The primary advantage of dedicated phase-noise analyzers. The cross-correlation method. Using a spectrum analyzer is the oldest, most straightforward, ...

Before we differentiate a spectrum analyzer and a network analyzer, it is important to understand what these two instruments are, and what function they perform. Thus, we give a basic overview of the ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...
