Why conduct an EMC prescan?
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.
- Pre-scan your device early to avoid FCC certification delays.
- Consider FCC restrictions for radio devices.
- Fix any design flaws to pass FCC tests with some headroom.
How can a prescan help prepare a product for formal testing?
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.
Understanding the common technical causes of initial EMC test failures is essential for anticipating potential delays and staying informed during the pre-compliance phase:
-Insufficient familiarity with EMC principles
-Failure to implement EMC principles effectively
-Misapplication of EMC regulations
-Unforeseen interactions among circuit elements
-Integration of noncompliant modules or subassemblies into the final product
-Uncontrolled environmental conditions such as humidity, temperature, and altitude leading to varied test results
-Testing power supplies separately instead of within the full product context
-Overlooking conducted RF from cables at low frequencies or radiated RF at high frequencies.
