Three new Modules for Yokogawa’s ScopeCorder Family
22 October 2015 -Yokogawa added new products to the range of plug-in measurement modules for Yokogawa’s DL850E/DL850EV ScopeCorder family, bringing the total number of modules available to 19. The new units are the 720211 high-speed (100 MS/s) 12-bit isolation module, the 720243 SENT monitor module (available only for the DL850EV Vehicle Edition ScopeCorder) and the 720254 4-channel 1 MS/s 16-bit isolation module.
Fully Automated MIPI M-PHY Transmitter Test Solution for Mobile Storage Devices
21 October 2015 – Tektronix announced the industry’s first fully automated physical layer transmitter test solution for the MIPI M-PHY 3.1 specification and Conformance Test Suite (CTS) 3.1. The solution supports M-PHY High Speed Gears 1, 2 and 3, PWM Mode (G0-G7), and SYS Mode and offers the industry’s lowest noise solution for M-PHY measurements when used with Tektronix DPO70000SX or MSO/DPO70000DX oscilloscopes and P7600 series probes.
Open Source USB Oscilloscope supports multiple Operating Systems
12 October 2015 - LabNation launched its open source USB oscilloscope, SmartScope. The development was funded by a Kickstarter campaign commenced in 2014. SmartScope runs on multiple operating systems and platforms such as smartphones, tablets and PCs. The lightweight SmartScope is powered directly from the host’s USB interface and combines the multiple functions of an oscilloscope, logic analyser and a waveform generator in an aluminium case measuring just 110.0 x 64.0 x 24.2 mm.
Tektronix offers PAM4 Analysis Solution for Real Time and Equivalent Time Oscilloscopes
05 October 2015 - Tektronix announced that its comprehensive set of analysis tools for emerging PAM4 modulation now operates on both DPO70000SX 70 GHz real time and DSA8300 equivalent time oscilloscopes. PAM4 is being adopted in the latest 400 Gigabit Ethernet standard by the IEEE P802.3bs working group for 400G (typically 8 x 50G) electrical and optical interfaces. Compared to traditional NRZ that uses two-level signaling, the four-level scheme used in PAM4 significantly increases signal complexity and places new demands on test equipment for performance and noise sensitivity.
Anritsu becomes Sales Representative for Teledyne LeCroy in UK and Ireland
02 October 2015 – Anritsu Corporation and Teledyne LeCroy have signed an agreement providing for Anritsu to become an authorised reseller of Teledyne LeCroy products in the UK and Ireland. Under this agreement Anritsu will provide the local sales and support service for Teledyne LeCroy in UK and Ireland, including customer demonstrations and technical support. The agreement also includes the transfer of Teledyne LeCroy sales staff in UK to Anritsu EMEA Ltd.
Tektronix expands ATI High Performance Oscilloscope Family with 50 GHz Model
30 September 2015 - Tektronix announced the expansion of its DPO70000SX Performance Oscilloscope Series to include 50 GHz and 23 GHz models. By extending the flagship 70 GHz model, the new 50 GHz product is ideal for engineers and researchers who want to take advantage of the superior low-noise performance of the patented asynchronous time interleaving (ATI) architecture for technologies such as 28 GBaud PAM4 and Kband frequency testing.
Ultra-Wide Bandwidth 5G Backhaul Signal Analysis
29 September 2015 – Tektronix implemented the SignalVu software on its family of DPO70000SX ATI Performance Oscilloscopes. This will allow researchers and others engaged in developing next generation wide- and ultra-wide bandwidth technologies such as 5G, cellular backhaul and radar to perform RF modulation measurements with unprecedented margins of error.

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.
