Fundamentals of Building a Test System: Rack Layout and Thermal Profiling

Every minute of every day, new projects are placed on the desks of test engineers with the expectation they develop measurement systems that not only meet specification requirements and release deadlines but also offer high quality and reliability. In an ideal world, engineers have the time and resources to perform in-depth research, modeling, and simulation to produce perfect systems. Unfortunately, real-world project schedules do not typically permit the time and resources to develop perfect systems. In a System Integration Study performed by Control Engineering in August of 2014, only 67 percent of system projects were completed on time and within budget. In a world of tight release schedules and demanding project timelines, it is important to consider the aspects of a measurement system that can impact the quality of measurements, which, in turn, can increase risk to schedule, cost, and performance. These aspects range from the instrumentation selected to the quality of the connections and cables to the implementation of the measurement methodology. An overlooked area, however, is the impact thermals can have on measurement quality and measurement system reliability.


This guide equips you with the knowledge to learn more about your design to avoid risk. By learning how thermals impact measurement quality, see basic design approaches, and explore thermal modeling tools for designing a rack measurement system.


Ensure you’re creating a successful automated functional test system with this guide on Rack Layout and Thermal Profiling.
