A spectrum analyzer is an essential instrument for RF and microwave circuit design. However, at first glance it seems to be an odd choice for analyzing high speed serial data channels. This article ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...

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, ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

We know [Happy Little Diodes] frequently works with logic analyzer projects. His recent wireless logic analyzer for the ZX Spectrum is one of the oddest ones we’ve seen in a while. The heart of the ...
