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 ...

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 ...

Wireless devices that periodically hang, interfere with other consumer products (like radios), or don't completely deliver as promised can turn consumers off, not only to the technology but to the ...

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 ...

Amateur radio transmitter testing webinar with Sebastian Westerholt on spurious emissions, ETSI setup, analyzer settings, and ...

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 ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

Noise is an annoying but unavoidable part of any engineering project. Fixing noise issues is hard enough, but even just measuring how much noise an amplifier adds to your signal is tricky without ...
