Tests show how trucks can reuse engine heat for power
Working with automotive manufacturer Scania, researchers from KTH Royal Institute of Technology have been testing semi trucks equipped with a system that converts exhaust heat into power — through a process called thermoelectric generation (TEG). The voltage produced by the system can power the truck and reduce the strain on the engine, explains researcher Arash Risseh.
Test solution targets 802.11ax high-efficiency wireless
An early access version of the WLAN Measurement Suite with support for the IEEE 802.11ax (draft 0.1) high-efficiency wireless draft standard has been announced by National Instruments. The WLAN Measurement Suite, combined with NI’s RF vector signal transceiver (VST), empowers engineers to measure the performance of their 802.11ax designs confidently in the presence of significant new changes to the 802.11 physical layer specification.
Detecting of partial discharge (PD) in rotating machines
A newly launched solution from HVPD enables the detection of partial discharge (PD) in rotating machines. The PDS Insight Machines’ technology can be used to detect and trend PD - a common cause of electrical failures in critical assets.
Driving the future of mobile computing
A 64-bit ARM v8-A processor test chip based on TSMC’s 10FinFET process technology has been introduced by ARM. Simulation benchmarks show power and efficiency gains relative to TSMC’s 16FinFET+ process technology, which is currently used to implement chips powering many of today’s premium smartphones.
64 GBaud BERT simplifies characterisation of PAM-4 devices
Keysight Technologies has introduced a M8040A high performance BERT for testing PAM-4 and NRZ devices that operate up to 64 GBaud. Engineers in validation labs and R&D who characterise receivers on the physical layer for the next generation of data centre interconnects will benefit from simplified test setups and repeatable and accurate results.
Arbitrary signal generators feature 125 MSa/s sample rate
Two new Arbitrary/Function Signal Generators, the SFG-205 and SFG-210 have been added to its line of educational and industrial test instruments by Global Specialties.The SFG-20X Series are single channel function/arbitrary waveform generators, capable of generating either a 5MHz sine wave (SFG-205) or a 10MHz sine wave (SFG-210).
Measuring solvent vapour permeability
Water and other vapours can permeate through the actual fabric of adhesives or mastics, sometimes in large volume. This can cause a huge variety of adhesion problems, including failure – water and its vapour are now thought to be the world’s most damaging contaminant.
500MHz switch card added to functional test platform
Two new products have been added to the GENASYS functional test platform by Marvin Test Systems (MTS). Building on the performance architecture of the GENASYS switching subsystem, MTS has added the GX7017 Integrated GENASYS Chassis to the GENASYS product line providing digital, analogue and high performance switching capability within a single, compact, 6U PXI chassis footprint.
Low noise filter expands power source output range to 500mA
A new high current ultra-low noise filter for Keysight Technologies’ B2961A and B962A 6.5 digit Low Noise Power Source can supply up to 500 mA while maintaining 10 µVrms and 1nVrms/√Hz (at 10 kHz) noise performance. With a starting price of less than $10K, the B2961A and B2962A are claimed to be the world’s only low-cost standalone power sources capable of sourcing at ultra-low noise levels.
Handheld wireless tester has 802.11ac capability
The next generation of the AirCheck handheld wireless tester has been released by Netscout Systems. The tool is available through Netscout’s CONNECT360 global channel partner program, and includes important new enhancements, such as troubleshooting and diagnosing Wi-Fi networks built using the increasingly adopted 802.11ac standard, access point backhaul testing, and free access to the Link-Live Cloud dashboard for more effective results ma...
