MIL-STD-461

MIL-STD-461 is a U.S. military standard that sets forth the requirements for the control of electromagnetic interference (EMI) in electronic and electrical equipment used in defense applications. The standard specifies how equipment should be tested for both emissions (the unwanted electromagnetic energy it generates) and susceptibility (its resilience to external electromagnetic interference). It encompasses various revisions to address evolving technology and requirements, ensuring that military equipment performs reliably in the electromagnetic environment it will encounter. Essentially, MIL-STD-461 aims to ensure compatibility and prevent interference between electronic systems used in military operations.
