March Dine and Learn
by Dan Lubar
A big supporter of innovation, Dan Lubar is a cross-disciplinary electrical engineer w/30 years of experience. Dan is a subject matter expert in today's "shortlist" of key fast-moving technology innovations: wireless(both fixed & mobile), electric utility transition (changing business models & infrastructure), and the twin software innovations of distributed trust infrastructure (aka Blockchain), and AI, what Dan likes to call "Big Data-driven machine learning", which has never really been possible until recently.

Satellite Navigation and Sensing
by Dr. Jade Morton
Satellite-based navigation has impacted nearly every aspect of our modern society. Yet, this powerful technology relies on extremely low power, vulnerable signals traversing a vast space to reach receivers on the Earth surface or near-Earth space environments. Many complex elements interfere with the signals along their propagation path, including plasma in the upper atmosphere, water vapor in the lower troposphere, as well as physical objects and electromagnetic sources in the user environments. These nuisance factors degrade and limit navigation systems performance. Understanding their effects on navigation signals is the pre-requisite for developing robust navigation technologies that can mitigate these elements impact.

The Right Time for Compliance Testing
|
Although a necessity, compliance testing is usually held off until an electronic device has gone through several design iterations. In fact, the product may be "ready for production" by the time compliance testing is even considered. In this case, it's probably too late. On the other hand, if the design is not yet resembling the final form factor and in its representative enclosure, then it's probably too early.
Despite the design engineers having used best practices and performed verification and validation testing, regulatory tests are difficult to pass on the first try. It is usually the case that some modifications to the design are required in order to pass. Knowing the design's shortcomings as early as possible saves time and cost in the product development cycle.
CEPD offers engineering support to our customers with regulatory compliance. We recommend that our customers perform engineering testing when the following are ready:
- The functional bugs have been resolved for the first hardware revision
- The unit's software is nearly completed
- The design resembles the final form factor
Following these steps allows for issues to be identified and debugged at the test lab and on the bench before going to the next revision.
So, when is the right time? The short answer is: As early as possible with the first revision of representative electronics and mechanical components.
Call CEPD! We are here to help you through the design, testing, and continuing support of your product! -CC
