Differential Probes with Bandwidth up to 25 GHz
29 October 2019 – Teledyne LeCroy announced the DH Series of differential probes, which come in bandwidths from 13 GHz to 25 GHz to address high-speed serial data debug and validation. The probes offer exceptionally low loading (200 kΩ DC), low noise, and a range of available tips for application flexibility.
GW Instek added new Mixed-Domain Oscilloscope
25 October 2019 - The GW Instek MDO-2000A is an advanced version of MDO-2000E mixed-domain oscilloscope. The selectable bandwidth range is upgraded to 300MHz. The full bandwidth ranges include 300MHz, 200MHz and 100MHz. The sampling rate has upgraded to max. 2GSa/s and the memory depth has also been upgraded to 20M/CH. Hence, the three major specifications of oscilloscopes have been improved.
Measuring and Evaluating Switching Parameters of SiC, GaN Power Devices
23 October 2019 - Tektronix offers a new software plugin for its AFG31000 Arbitrary/Function Generator that makes it possible to perform crucial double pulse testing in less than a minute, saving a significant amount of time when compared to alternative methods. Measurements are taken with an oscilloscope.
I3Cbus Trigger, Decode, Measure, Eye Diagram Solution
15 October 2019 - The new I3C Trigger+Decode (TD) option for Teledyne LeCroy Oscilloscopes provides high performance triggers and transparent color-coded decode overlays, protocol tables, and search capabilities.

A Comparison between Oscilloscopes and Spectrum Analyzers
Whether it is for a land survey searching for minerals on Earth, or for a space exploration in search of alien life forms, the analysis of any signal boils down to looking at its time and frequency information. While an oscilloscope displays a signal with respect to time, a spectrum analyzer shows it with respect to frequency. Both of these tools are very important in any signal analysis application. This article explains the difference between oscilloscope and spectrum analyzer using examples.

A simple method to verify the bandwidth of your probe
In oscilloscopes or oscilloscope probes, bandwidth is a measure of the width of a range of frequencies measured in Hertz. Specifically, bandwidth is specified as the frequency at which a sinusoidal input signal is attenuated to 70.7 percent of its original amplitude, also known as the -3 dB point. Most oscilloscope companies design the scope/probe response to be as flat as possible throughout its specified frequency range, and most customers simply rely on the specified bandwidth of the oscilloscope or oscilloscope probes, wondering if they are indeed getting the bandwidth performance at the probe tip. Now you can use these step-by-step instructions to simply measure and verify the bandwidth of your probe with an oscilloscope you may already have.
