There are dozens of free PCB-layout and schematic packages available on the Web. Often they are stripped-down versions of more complex packages available for licensing. Often, the process of upgrading from freeware to more sophisticated versions is pretty easy. If your circuit needs are generally confined to relatively straightforward two-layer boards, here are a few […]
Test and Measurement Tips
Waveguide Gunn diode oscillators are mechanically tunable
A new line of waveguide Gunn diode oscillators are candidates for electronic warfare, electronic countermeasures, microwave radio systems, military and commercial communications systems and more. Pasternack’s new mechanically tunable waveguide Gunn diode oscillators cover WR-90, WR-42 and WR-28 waveguide sizes and support X, K and Ka bands. All models in this line operate at 50 […]
Catch that glitch: Finding race conditions
Among the problems circuit designers have to contend with in their fast and complex electronic environment are race conditions. The term used to be exclusively applied to electronic logic problems but has now been adopted by software engineers working on multithreaded programs. Briefly, software race conditions arise in multithreaded software when multiple threads attempt to […]
Analyzer/exerciser/jammer platform for PCI Express 5.0 handles multiple users
The VIAVI Xgig 5P16 platform now supports analyzer bifurcation and multi-user functionality, enabling multiple users and simultaneous tests on a single platform. These enhancements allow simultaneous protocol analysis for PCI Express® (PCIe) 5.0 data traffic at all layers of the stack, speeding time-to-market and controlling total cost of ownership (TCO) for development and production of […]
12U 75 kW, 16U 100 kW programmable dc supplies provide up to 6 kVdc, 8 kA dc
New models for the TS Series MagnaDC programmable power supply line expand it to 75 kW in 12U (21-in high) and 100 kW in 16U (28-in high), voltage ratings up to 6,000 Vdc floating, and current ratings up to 8,000 Adc. The new 75-kW 12U and 100 kW 16U TS Series models occupy less than […]
Software lets data loggers/scopes stream data to cloud storage
The PicoLog Cloud data logging software enables any Pico data logger or real-time oscilloscope to save data to a local disk or stream the capture directly to a secure online Cloud store. Uers can set up and control captures on a source PC and then remotely view them on any number of client devices running […]
T&M asset management software includes equipment management, barcode creation
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 […]
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 […]
