How Do I Measure and Compare Feedthrough Filter Performance?
Have you ever wondered how to test feedthrough filters to verify their actual performance versus their ratings, or to compare multiple filter options to select the best performer? Is it possible to perform measurement on filtering performance through the MHz and GHz range without having the full-scale system and large test chamber available?
In this week’s featured White Paper from NexTek, we will guide you through the process of performing your own filter performance measurements! Beginning with the basics of filtering measurement, moving on to the construction of a suitable small-scale DUT Chamber, and finishing with a detailed review of the pluses and minuses associated with the example test chamber design…this article should answer all of your questions about RFI/EMI filter measurement!
Perform accurate comparisons without requiring the filter be installed into a full-scale system for testing, saving time and money during the component selection and comparison segments of product development. You will be an expert by the time you finish the article, especially since the article includes a sample test chamber drawing that you can build yourself!
