Transmitter Testing Software for USB 3.1 Type-CTM Designs
12 May 2016 - Keysight Technologies introduced the U7243B USB 3.1 transmitter performance validation and compliance test software for the USB 3.1 Type-C specification. The test software allows authorized test centers to test USB 3.1 Gen2 SuperSpeed Plus 10 Gbps devices with Type-C implementations and gives in-house test and performance validation engineers the tools to ensure devices comply with the USB 3.1 Gen2 Type-C specification.
100G Ethernet Compliance Test Software
10 May 2016 - Keysight Technologies introduced a comprehensive compliance application software for testing electrical characteristics of 100G four-lane attachment unit interface (CAUI-4) networking applications. The software supports the IEEE 802.3bm standard, which accommodates optical networking advances and enables higher density applications.
First CXPI Triggering and Decode Options for Oscilloscopes
05 May 2016 - Keysight Technologies announced the clock extension peripheral interface (CXPI) decoding and triggering options for its InfiniiVision 3000T and 4000 X-Series oscilloscopes. These are the only oscilloscopes available today that can decode and trigger on the CXPI bus. These new capabilities improve engineers’ efficiency in debugging the physical layer of CXPI serial buses, which are used primarily in automotive applications.
Measure high Frequency Motor Drive Common-Mode Currents
03 May 2016 - Power Electronic Measurements (PEM) Ltd launched new non-contact current probes for measuring HF common mode currents in Variable Frequency Drives (VSDs) used to control AC motors. The new CMC series of current probes, using Rogowski technology, empower engineers to assess the magnitude of the threat posed by HF common-mode currents, that can damage motor bearings and interfere with nearby electrical equipment.
USB Oscilloscopes provide Functionality of six Instruments
28 April 2016 - Pico Technology expanded its 2000 Series PicoScope PC based oscilloscopes with new models. The PicoScope two-channel, four-channel and mixed-signal models have the functionality of an oscilloscope plus a logic analyzer (on MSO models), spectrum analyzer, function generator, arbitrary waveform generator, and serial bus analyzer with support for 15 protocols included as standard. They are USB-powered and come in an ultra-portable package that can be easily transported in a laptop bag.
1GSa/s Sample Rate USB Oscilloscope
19 April 2016 - On the 87th China Electronics fair in Shenzhen (08 April to 10 April) Hantek launched a new four channel 1GSa/s sample rate USB oscilloscope. The Hantek 6XX4 series features a bandwidth of up to 250 MHz, with optional extra single-channel signal generator and vehicle test functions.
Oscilloscope Firmware Update adds PAM-4 BER and MultiScope Support
08 April 2016 – Keysight Technologies introduced two software updates for its real-time oscilloscope products. The software updates are currently available in the Infiniium oscilloscope firmware version 5.60. The N8827A PAM-4 analysis software update adds bit error ratio (BER) capabilities for 4-level pulse amplitude modulation (PAM-4) based signals. The N8834A MultiScope software update adds support for Keysight’s InfiniiVision oscilloscopes.

Oscilloscope Probes – Vital Link in the Measurement Chain
Signal measurement results can only be as accurate as the test and measurement tools in use. As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit. This article looks at voltage probing considerations for embedded system and digital design debugging applications.

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.
