USB 3.1 Compliance Test with Tektronix DPO/MSO70000 Oscilloscopes
23 January 2015 - Tektronix released a comprehensive set of USB 3.1 compliance test solutions that allows designers to quickly verify designs against the latest USB specifications and achieve fast time to market while minimizing costs. The new release expands Tektronix' already extensive USB 3.1 and USB 2.0 test capabilities to include a new USB 3.1 receiver test solution supporting the 10 Gb/s data rate, a new USB Power Delivery test solution and a new USB Type-C cable test solution.
WLAN Digital Storage Oscilloscope
21 January 2015 - Velleman offers the world's first WLAN dual channel digital storage oscilloscope. The WFS210 is a compact, portable battery powered fully featured two channel oscilloscope. Instead of a built-in screen it uses a tablet (iOS, Android) or a PC (Windows) to display the measurements. Data exchange between the tablet and the oscilloscope is via WLAN.
USB Oscilloscopes - Product Overview (Low-end)
USB oscilloscopes are are becoming increasingly popular. Nevertheless there is a wide range of instruments available starting from less than one hundred up to several thousands of dollars. The following comparison chart provides a list of products with some important selection criteria. The list covers products in the low-end price range from 100 to 500 USD and with a bandwidth of at least 50 MHz. Most of USB PC scopes are pure digital oscilloscopes (DSO) but some offer also mixed-signal functions (MSO) or even additional features such as arbitrary waveform generator (AWG), logic analyzer, protocol analyzer or spectrum analyzer.
Keysight adds Touch Screen and Zone Triggering to Mainstream Oscilloscopes
14 January 2015 – Keysight Technologies introduced InfiniiVision 3000T X-Series digital-storage and mixed signal oscilloscopes with intuitive graphical triggering capability. This new oscilloscope series delivers capacitive touch screens and zone triggering to the mainstream oscilloscope market for the first time. The scopes help engineers overcome usability and triggering challenges and improve their problem-solving capability and productivity.

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.
