Test and measurement engineers looking to speed up and simplify calibration of their fleet of test and measurement equipment have a powerful new tool with the upgraded version of the popular cloud-based asset management software CalWeb. Managing large fleets of test and measurement equipment for calibration services can be a time-consuming, manual process. CalWeb solves […]
Test and Measurement Tips
Signal creation/analysis tool speeds development process for RF components
The new R&S VSESIM-VSS signal creation and analysis tool speeds the development process for RF components. It is particularly useful for the wireless, automotive, and aerospace and defense industries as well as for manufacturers of active components and systems. New wireless and satellite technologies offer ever wider frequency ranges and involve increasingly demanding requirements. Realistic […]
Don’t touch that! Things they don’t teach you in circuits lab
The domain of most electronics engineers these days is confined to voltage levels ranging from microvolts on up to a few hundred volts. But when electronic equipment fails or there’s a problem with facility wiring, these same engineers may, in a pinch, be called upon to do basic troubleshooting of power levels far beyond their […]
1U-high chassis includes dual ac input and monitoring
A new option is available for the 1U high OpenVPX, CompactPCI, and VME64x enclosures for power and monitoring. The 1U chassis supports various configurations of 3U/6U OpenVPX, or 6U CompactPCI or VME64x backplanes. The enclosure provides dual, non-redundant ac inputs with 12-V power which can be converted to 5 and 3.3 V as well. A […]

ABI BoardMaster is a unique, versatile, self-contained, and easy-to-use electronics test system, housed in a convenient 19-in rack case. It is an all-in-one unit featuring a comprehensive set of built-in test instruments, complete with a built-in Windows 10 PC and special software, […]
FPGA-based instruments: Inside the Moku benchtop test gear
The roots of the venerable Moku:Lab, Moku:Go and Moku:Pro test gear from Liquid Instruments can be traced back to a sophisticated interferometer set to orbit the earth. As part of his PhD work, Liquid Instruments CEO Daniel Shaddock documented the design of the control system for the LIGO mirror, which had to be stabilized at […]
Broadband VNA system provides single-sweep coverage up to 125 GHz
The VectorStar ME7838AX/EX series is the first vector network analyzer (VNA) broadband system to offer single-sweep coverage up to 125 GHz/110 GHz with guaranteed and typical specifications. The VectorStar ME7838AX/EX system’s ability to sweep and provide characterized data through 125 GHz provide design engineers with the ability to significantly and confidently improve their device models […]
Power-and-ground-only VPX backplanes target system designs based on open standards
Power- and ground-only VPX backplanes include flexible design options that meet the needs of today’s high-speed, open standards-based system architectures. These include OpenVPX, CMOSS- and HOST-compliant hardware as well as systems aligned to The Open Group Sensor System Open Architecture (SOSA) Technical Standard or even custom designs. System designers can cost-effectively test and build open […]
Server-grade PXIe controller designed for hybrid PXI Express-based testing systems
A server-grade PXIe controller, the Intel Xeon E-2276ME-based PXIe-3988, combines state-of-the-art Intel Core processors and up to 64 GB of DDR4 2400-MHz memory. The PXIe-3988 employs multiple computing engines on a single processor and can run four independent tasks simultaneously. Specifically designed for PXI Express-based testing systems, the PXIe-3988 provides a rugged and stable platform […]
How to look at magnetic domains
A central concept in magnetism is the domain, discovered in 1906 by Pierre-Ernest Weiss. He theorized that in any magnetically permeable material, a large number of mostly microscopic regions existed as separate walled-off entities. In each of these entities, called domains, the atomic moments align in parallel when magnetized. But the alignment of individual domains […]
