New System to Enhance Automotive Electronics Testing
Munich, Wednesday, 5 March 2025.
A multifunctional immunity test system simulates electromagnetic disturbances, aiding manufacturers in meeting ISO 7637 and CISPR 25 standards for electronic product reliability.
Advanced Testing Capabilities
The newly developed system offers comprehensive testing parameters, including voltage ranges from -100V to +200V and pulse durations from 10 microseconds to 200 milliseconds [1]. Significantly, the system integrates electrostatic discharge (ESD) testing capabilities up to ±15 kV, aligning with IEC 61000-4-2 requirements [2]. This integration enables manufacturers to conduct thorough electromagnetic compatibility assessments in a single testing environment.
Industry Standard Compliance
The testing system has been specifically designed to meet rigorous European automotive standards, particularly ISO 7637 and CISPR 25 [1]. For automotive electronics manufacturers, this comprehensive testing capability is crucial as it evaluates components ranging from Engine Control Units (ECUs) to Advanced Driver-Assistance Systems (ADAS) [1]. The system’s capabilities extend to RF conducted immunity testing across frequencies from 4 kHz to 1 GHz, as demonstrated by the latest NSG 4070D implementation [3].
Market Impact and Implementation
Early adoption case studies demonstrate significant benefits for manufacturers. One automotive lighting manufacturer has already integrated this testing protocol, leading to early identification of LED driver circuit vulnerabilities before mass production [1]. The system’s implementation is particularly relevant for the European market, where electromagnetic compatibility testing facilities must maintain compliance with updated standards. Testing services now encompass a broader range of components, including instrument clusters, seat control units, and telemetrics control units [5].
Future Implications
The system’s versatility extends beyond basic compliance testing, incorporating advanced features such as real-time monitoring and remote control capabilities [3]. This technological advancement arrives at a crucial time when automotive electronics are becoming increasingly sophisticated, requiring more comprehensive testing protocols [5]. The integration of multiple testing capabilities into a single system represents a significant efficiency improvement for manufacturers, potentially reducing testing time and associated costs [1][3].
