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 ...

The Zero Span function of spectrum analyzers is very useful when the instrument is used in time domain measurements. In this video, an AM signal is used for the testing and analysis throughout the ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

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 ...

The easiest way to envision a spectrum analyzer is to begin with an oscilloscope that plots magnitude versus time. Then swap frequency for time—and voilà—a spectrum analyzer! A gross simplification ...

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 ...

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 ...

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 ...

In the fast-paced world of electronics testing and measurement, spectrum analyzers play a critical role in assessing and understanding radio frequency signals. Many professionals, therefore, choose to ...
