The test fixture then exposes the specimen to controlled levels of electromagnetic radiation within a specific frequency range. The frequency range is crucial as it simulates different environmental conditions encountered in real-world applications.
After exposure, engineers analyze the performance of the component or system using specialized equipment such as spectrum analyzers and field strength meters. Any anomalies detected during this analysis are documented for further investigation. This process helps identify potential areas for improvement and ensures that the final product meets all required specifications.
The SAE J1113 12 Radiated Immunity Stripline Test is not just a compliance requirement but also a valuable tool in ensuring long-term reliability and safety of automotive components and systems.
