Making final EMC measurements can take a long time. It is extremely inefficient to take a final measurement at every frequency in the compliance frequency range, whether there is an emission or not. Prescans are used to generate a suspect list of emissions from a device under test (DUT), allowing you to focus final measurement efforts only on frequencies with known emissions, saving time and money.

EMC risk assessment and testing, if performed during the design cycle of a product’s development phase, will aid in the identification of any components emitting electromagnetic properties. An EMC pre-scan of a product for electromagnetic emissions results in product modification to eliminate emissions prior to the required formal EMC test.
