Test and measurement with LabVIEW

July 20, 2018 By David Herres Leave a Comment

LabVIEW is an awesome product created and maintained by National Instruments. It consists of systems engineering relating to test, measurement and control of instrumentation, devices and machinery, and it is currently used worldwide in numerous applications. Rather than endless lines of textual coding, LabVIEW has a simple graphic interface where devices such as an oscilloscope […]

Interoperability testing for the Internet of Things

June 25, 2018 By Lee Teschler Leave a Comment

The Internet of Things might also be thought of as the internet of interoperable things. A systematic testing regime can help uncover problems when devices work in concert. DELMAR HOWARD, INTERTEK GROUP PLC The Internet of Things (IoT) is growing at an exponential rate. In three years, the number of IoT-enabled products is expected to […]

Measuring energy without getting fooled

October 5, 2017 By David Herres Leave a Comment

energy power time

James Prescott Joule, in formulating what is now known as Joule’s Law, found that various forms of energy such as mechanical, electrical and heat are essentially identical and can be changed one into the other. His work formed the theoretical basis for the First Law of Thermodynamics. Joule further investigated the phenomenon of magnetostriction. He […]

When waveform read-outs come from a SPICE simulator

November 8, 2016 By David Herres 1 Comment

spice probe display

In a simpler time there wasn’t a great need for electronic simulation because equipment composed of discrete components could easily be bread boarded and powered up to try out ideas. This approach is now unfeasible thanks to billion-component ICs, multi-gigahertz bandwidth requirements, parasitic impedances, and electromagnetic interference issues. Rather than manually building and testing multiple […]

Basics of modeling transistors

October 16, 2014 By David Herres Leave a Comment

PNP symbols

By David Herres All transistors operate according to the exact same physical principles as diodes, the only difference being that they have greater complexity because there are additional P-N and N-P junctions and accordingly more terminals. As with simple diodes, a transistor junction conducts when it is forward biased and does not conduct when it is reverse […]
