Rigol releases Software for Testing Switching Power Supplies
28 November 2014 – Rigol Technologies EU has released a new PC Software, which enables users to perform standard measurements on switching power supplies. This software, in combination with Rigol oscilloscopes (series DS/MSO2000A, DS4000 or DS6000) allows customers to set up small test systems, which represent a reasonably priced alternative for measuring switching power supply parameters during the development phase.
New Measurement and Graphing Capabilities for CAN FD Analysis
27 November 2014 – Teledyne LeCroy announced the addition of unique measurement and graphing capabilities to their CAN Flexible Data-Rate (FD) serial trigger and decode solution. The new CAN FD solution (CAN FD TDM) enables designers using this new standard to gain unprecedented insight in to their systems, correlating physical layer signals and protocol layer data on a single display while also measuring and plotting bus performance. These tools can be used to measure the time between two CAN or CAN FD messages, or from a message to an analog signal. These measurements can then be extracted to recreate analog waveforms.
Transmitter Testing Solution for USB 3.1
26 November 2014 – Keysight Technologies introduced transmitter (TX) test support for the USB 3.1 specification with the U7243B USB 3.1 transmitter performance validation and compliance test software. The test software allows authorized test centers to certify SuperSpeed USB and SuperSpeed USB 10-Gbps devices and gives in-house test and performance validation engineers the tools to ensure their devices comply with the USB 3.1 specification. The test software operates on Keysight’s 90000 X-, Q- and Z-Series Infiniium real-time oscilloscopes with bandwidths of 16 GHz and higher. Access to the test signals through a USB test fixture is required.
Reconfigurable 8 Channel Oscilloscope with 14-bit Resolution
25 November 2014 - National Instruments introduced with the NI PXIe-5171R a reconfigurable oscilloscope with eight calibrated analog input channels, 250 MHz bandwidth, 250 MS/s sample rate, and 14-bit resolution. The PXIe-5171R is a general-purpose module that features a user-programmable FPGA for inline signal processing, protocol decoding, and advanced trigger schemes without dead time.
Rigol introduces new 50MHz Economy Digital Oscilloscope
24 November 2014 – Rigol Technologies EU announced the expansion of their DS1000Z Mid-Range Digital Oscilloscope series with a 50 MHz version with a large 7” screen. The DS1054Z version incorporates most of Rigol’s breakthrough technologies and delivers superior performance and functions. The new model was mainly designed for first-time-users and also for education, technical schools and universities as well as teaching labs, test and physics labs.
10 Tips for selecting an Oscilloscope
The oscilloscope is one of the most important tools used in the design, repair and maintenance of electronics. Nevertheless the selection of the right type and configuration for your application is not an easy task. We listed some important points to consider.
High Bandwidth, low Noise Oscilloscope Probe for Power Integrity Measurements
21 November 2014 – Keysight Technologies introduced the industry’s highest bandwidth and lowest noise oscilloscope probe for making power integrity measurements to characterize DC power rails. The new Keysight N7020A power-rail probe specifications are tailored for a wide variety of DC power-rail measurements. Probe specifications include very low noise, a large ± 24-V offset range and 2-GHz bandwidth.

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.
