Testing and Debugging of Automotive Ethernet
25 November 2019 - Pico Technology released a new BroadReach decoder/analyzer package that simplifies Automotive Ethernet integration testing and debugging. The package includes a novel non-intrusive Software Directional Coupler to separate up- and downstream traffic on full-duplex communication lines.
200 MHz to 1 GHz Oscilloscopes with 12-bit Resolution
06 November 2019 – Teledyne LeCroy launched the WaveSurfer 4000HD High Definition Oscilloscope (HDO), the first in its class to feature 12-bit vertical resolution at all times, showing clean, crisp waveforms on a bright, 12.1” touch screen display. WaveSurfer 4000HD is available in bandwidths from 200 MHz to 1 GHz, with sample rates of up to 5 GS/s and up to 12.5 Mpts of acquisition memory on each channel (25 Mpts interleaved). It offers versatile built-in capabilities for embedded systems debug and is compatible with Teledyne LeCroy’s comprehensive probe offerings.
Portable Oscilloscope with USB, LAN or WiFi Connection
04 November 2019 - TiePie engineering introduced the WiFiScope series oscilloscopes. The new range WiFi oscilloscopes can be used via an ethernet connection (LAN, WiFi or WAN) but also still with a USB 2.0 / 3.0 connection. The built-in battery gives the WiFiScope the possibility to perform fully wireless measurements. Measurements can then be performed completely galvanically isolated, and over long distances.
200 MHz 2-Channel Oscilloscope with 24MPts Memory
30 October 2019 - RIGOL Technologies expands its oscilloscope portfolio with the new DS1202Z-E 200MHz Oscilloscope. The DS1202Z-E comes standard with 2 analog channels, 24MPts of deep memory, a 60,000 frame segmented record mode, standard serial decode and triggering, high resolution FFT, 15 trigger types and 37 integrated measurements making the DS1202Z-E a powerful and capable debug tool for design engineers.
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.

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.
