Keysight extends Duration of Instrument Service
02 June 2015 - Keysight Technologies has extended the available service period beyond the industry standard for many of its popular instruments that are no longer in production. The new Extended Service Period (ESP) program addresses a frequent request from customers who need to keep crucial test equipment operating over the life of multi-decade programs. In addition, Keysight is now offering multi-year Warranty Assurance plans that enable end users to lock in peak instrument performance for up to 10 years.
Decoding of 8b/10b Buses with Oscilloscope
26 May 2015 - added a new option to its R&S RTO oscilloscope. The new R&S RTO-K52 decoding option helps developers design, verify and debug modules with 8b/10b encoded buses up to 6.25 Gbit/s. At the push of a button, the R&S RTO uses the option's full autoset function to determine the channel, decision level and bit rate settings, allowing developers to quickly start measuring. All of these settings can be readjusted manually.
TiePie releases new Version of Cross-platform SDK
18 May 2015 - TiePie released the new Version 0.5 of the LibTiePie library for its USB oscilloscopes. LibTiePie is available for Windows and various Linux platforms, including Raspberry Pi, Beaglebone Black, RIoTboard and Wandboard Dual. LibTiePie supports the USB oscilloscopes Handyscope HS5, Handyprobe HP3, Handyscope HS4 and Handyscope HS4 DIFF.
New PicoScope drivers for MATLAB
15 May 2015 - Pico Technology updated the MATLAB Instrument Driver package for the PicoScope 3000 Series to support the new PicoScope 3000D and 3000D MSO oscilloscopes. The MATLAB Generic Instrument Driver allows to acquire data from the PicoScope 3000 Series High-Performance Oscilloscopes and control the signal generator. The data could be processed in MATLAB using functions from Toolboxes such as the Signal Processing Toolbox.
Rohde & Schwarz received 2015 Global Frost & Sullivan Award
12 May 2015 - Based on its recent analysis of the oscilloscopes market, Frost & Sullivan recognises Rohde & Schwarz with the 2015 Global Frost & Sullivan Award for Competitive Strategy Innovation and Leadership. Within just five years of entering the oscilloscope market, Rohde & Schwarz developed an impressive product portfolio that helped it expand its footprint globally. Recognising early on that penetrating this market would be a challenge, Rohde & Schwarz focused on making value additions to its solutions by offering new capabilities and/or enhancing existing solutions.
TiePie updates its Multi Channel Oscilloscope Software
11 May 2015 - TiePie engineeing offers the newversion 1.32.1 of the Multi Channel oscilloscope software for download. A demo version is also available, which can be used without connecting measuring instruments. Many changes have been made to add new functionality and to improve basic operations in the software.
Yokogawa releases new Firmware for its ScopeCorder Instruments
08 May 2015 - Yokogawa has released firmware Version 3.20 for the DL850 ScopeCorder series of instruments, which combine the features of a high-speed oscilloscope and those of a traditional data acquisition recorder in a single, portable instrument. A key feature of the new firmware is direct file saving into the Mathworks MATLAB(R) data analysis and visualisation environment, offering users quicker and easier import of measurement data.

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.
