Abstract
A variety of electromagnetic interference (EMI) issues can emerge during the development of an astronomical instrument impacting project scope, budget and schedule. Furthermore, if the problem is detected at the observatory it would lead to delay the commissioning of the instrument or can degrade the instrument operation performance. To reduce the interference at levels that no longer represent a problem, namely, to achieve the instrument’s electromagnetic compatibility (EMC) its developers need to tackle the problem in an integrated approach along the entire project cycle development, starting at the early stages. In this paper we dig into some reported EMI issues related to astronomical instrumentation and the proactive measures taken in some observatories to preserve EMC. We present the main practices to achieve EMC, from the electrical engineering perspective, and we identify the key aspects that the project team needs to take into account from the systems engineering and project management perspectives.
