![]() Test objectives are uniquely determined by the equipment design. The objective of all EMC tests is to verify that the EUT meets its functional requirements in an adverse EM environment. Essentially, five steps are involved in performing an EMC test regardless of whether it is for design/development or for formal acceptance:įor this article, each step of the test plan is considered independently, but keep in mind that all five steps are interlinked. But it would help if the planning organization had an EMC-knowledgeable engineer to do the work and act as the mentor for the other designers. In any case, test planning is important, and if prayer is an element of the plan, then the plan is flawed.Ĭreating a sound EMC testing program isn’t that difficult. If the EUT is a $20 hand-held game with a digital display, it is not likely to receive the same level of scrutiny as a $600,000,000 interplanetary spacecraft-especially in the area of susceptibility. ![]() When the testing was finally completed, it had taken about four days to do the job, but there never were any in-the-field failures.Ī test effort primarily is a function of the amount of risk that the manufacturer or customer is willing to accept. After accounting for the time required to run a full equipment cycle for each mode at each receiver bandwidth and antenna position and calculating that it would take 13.46 years to perform all the testing for the data set they wanted, the company changed its requirements. ![]()
