CAN FD Monitoring Module for Yokogawa ScopeCorder
18 April 2018 - Yokogawa introduced a new CAN FD monitoring module for its ScopeCorder family of portable data-acquisition and recording instruments. The new 720242 plug-in module is compatible with the DL850EV (Vehicle Edition) instrument and the new DL350 ScopeCorder fitted with the /VE option.
Differential Probes for Measurements up to 6000 VRMS
16 April 2018 – Teledyne LeCroy introduced its HVD3000A series of high-voltage differential probes—the 1-kV safety-rated HVD310XA, the 2-kV safety-rated HVD3206A and the 6-kV safety-rated HVD3605A. These new probes serve the complete spectrum of power-electronics applications while providing 1% gain accuracy, a differential-voltage range of up to 1500 V (DC + peak AC), and high offset ranges.
New Firmware adds Frequency Response Analysis to GW Instek MSOs
09 April 2018 - GW Instek launched a new firmware for the MSO-2000EA and MDO-2000E mixed-signal oscilloscopes which adds a frequency response analysis function. The new firmware V1.34. FRA software can be downloaded for free from GW Instek website. After the installment, a standalone instrument, via arbitrary waveform generator, oscilloscope, and FRA software, allows users to obtain DUT’s FRA characteristic curve plot (Bode plot).
5-in-1 Oscilloscopes with large Touchscreen
04 April 2018 - Teledyne LeCroy announced the WaveSurfer 3000z oscilloscopes, which expand the existing WaveSurfer 3000 bandwidth range above and below that of earlier models, while also bolstering functionality for power-electronics testing. In addition, the new models provide more processing power and memory. All WaveSurfer 3000z oscilloscopes feature a large 10.1" capacitive touch screen, a vast set of debug and analysis tools, multi-instrument capabilities, feature/option upgrades, and support for a wider probe range.
Stackable USB Digital Storage Oscilloscope
28 March 2018 - Advantech launched two USB digital storage oscilloscopes with 200 MHz bandwidth and up to 1 GS/s sample rate. The 2 channel instruments feature up to 128 MS/ch waveform memory for high speed data acquisition. A special feature is that up to 6 instruments can be stacked resulting in up to 12 channels.
Affordable Mixed Signal Oscilloscopes with 200 MHz Bandwidth
22 March 2018 - B&K Precision announced their latest digital oscilloscope 2560 Series with DSO and MSO models. The oscilloscopes feature a sample rate of 1 GSa/s, 200 MHz bandwidth and 14 Mpts record length. The front panel boasts a large 8" widescreen with 256-level color gradient, 4 analog channels, and logic analyzer.
400G Input Modules for Sampling Oscilloscope
14 March 2018 - Tektronix introduced two new optical modules for its DSA8300 sampling oscilloscope that offer the industry's highest sensitivity and lowest noise, giving manufacturers the confidence they need to increase production capacity and improve yields for 400G designs moving into production. Tektronix also announced enhanced support for the latest 400G PAM4 TDECQ measurements with a software package optimized for 4 channel parallel processing for high throughput manufacturing test.

Digitizer and Oscilloscope - Equal Alternatives?
Can a digitizer be used as an oscilloscope? What is the difference between an oscilloscope and a digitizer? Should I better use a digitizer or an oscilloscope in my next application? These are interesting questions and the best way to start to answer these is the look up the dictionary definition of an oscilloscope: "An electronic instrument used to measure changing electric voltages. It displays the waveforms of electric oscillations on a screen."

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.
