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 ...

The Rigol DSA815 spectrum analyzer The idea of “seeing” RF has always intrigued me, but short of some futuristic goggles, an RF spectrum analyzer is about as close as one can get. And for those of us ...

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 ...

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 ...

Vortex light carries orbital angular momentum (OAM) characterized by exp(ilθ), where θ is the angular coordinate and l is the topological charge (TC) 1. OAM beams have been widely used in a variety of ...

Agilent has introduced a new RF analyzer that should be of interest to RF Report readers. The FieldFox handheld RF analyzer offers network analyzer and spectrum analyzer functions from 2 MHz to 4 GHz ...
