The special EMI/EMC testing tools are the instruments and software used to check whether a product complies with EMI and EMC standards. The assessment process involves measuring how well an item can work without causing electromagnetic interference or signals accidentally and how well it can resist disturbances from external sources. During this testing, some commonly used EMI equipment included spectrum analyzers, signal generators, near-field probes, and EMI receivers. This would ensure that the electronics meet the required rules and function well in various kinds of environments.
