A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...

This video demonstrates how to use the peak function of a RIGOL spectrum analyzer. In this experiment, the DG4000 arbitrary waveform generator is used to source the signal, while the DSA815 spectrum ...

Having a scope in a home lab used to be a real luxury, but these days, its fairly common for the home gamer to have a sophisticated storage scope (or two) hanging around. Dedicated spectrum analyzers ...

I suppose most of us have had the experience of going to the mailbox and seeing that telltale package in the white plastic bag, the sign that something has just arrived from China. This happened to me ...

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 ...
