Solar cells have been increasing in efficiency since their invention. Perovskite looks to provide the next increase at a reasonable cost.
Engineers usually perform and assess Monte Carlo analysis incorrectly, which can result in wrong design decisions.
It only takes 3µA of current to fail an EMC test, and a connector can produce that much.
As products emerge and networks assemble, the test-equipment industry must keep up with standards, production, and deployment.
Ransom’s speech at EDI Con 2018 encompasses life, economics, values, and responsibility and it comes with a request.
The enclosures around your electronics must survive impacts, high temperatures, and general abuse. Models can uncover hidden defects not visible inside your molded parts.
In another case of failed capacitors, this classic meter needed some power-supply capacitors replaced, and the diodes that came with them.
You need both mathematical equations and simulation, often in tandem, to produce accurate worst-case analysis. You also need accurate model correlation, which often takes work, before applying tolerances.
When developing satellite electronics, testing occurs throughout all stages of spacecraft development, from characterising the performance of parts to validating proof-of-concepts at prototyping, and post-launch in-orbit verification.
At Transcat's Rochester, N.Y. lab, we gave an HP 34401A DMM a checkup. The meter's readings were disappointing, but it was a worthwhile reality check.
