This video shows how to use the available trace functions in RIGOL’s series of Spectrum Analyzers. In this experiment, the DG4000 arbitrary waveform generator is used to produce the signal that will ...

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 ...

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 ...

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 ...

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 ...

Newnan, GA. The new Yokogawa AQ6375B is an optical spectrum analyzer operating in the short-wavelength infrared region (SWIR), covering wavelengths from 1,200 to 2,400 nm. With a design based on the ...

While it’s seldom necessary (post-installation, anyway) to test the physical-layer behavior of a wired LAN infrastructure, the same cannot be said for wireless LANs. Many elements, including fading, ...
