We live in a world of high connectivity and our expectations of uninterrupted communications are equally high. These expectations are top-of-mind for embedded application developers at every stage of development. As such, just putting the hardware components of the application together and firing them up is not enough. Once the design parts (HW and SW) are integrated, then the full system testing beyond that of mere functionality begins.
The results of RF emissions and susceptibility testing help designers modify their application to keep end-users’ expectations in mind. However, test results are only as good as the test set-up. Knowing what frequencies line up with each of the signals of the applications computing core is key. So, it’s highly advisable to always consult your hardware vendor when setting up testing. Application engineering teams (like those at Kontron) have incredible knowledge no only with respect to the hardware the vendor provides but also about the various places and circumstances in which the hardware is used. They are here to help and not taking advantage of such a resource would be unwise to say the least.
Attached is a list of the clock frequencies needed when conducting RF emissions and susceptibility test on an application based on a computer-on-module solution with the Intel® Core™ Duo processor (i.e. the Kontron ETXexpress-CD module) at the system core.
Information such as this and much more is at the fingertips of vendor application engineering teams. So, make sure that consulting them is on your test set up checklist.
