Talk to Our Experts

Overview

Reliable immunity and susceptibility testing plays a vital role in safeguarding electronic systems from external electromagnetic disturbances. This content provides an in-depth look at the importance, methodologies, and tools used to verify system robustness under real-world interference conditions. These testing strategies are essential to ensuring that devices, systems, and infrastructures function reliably when exposed to radiated or conducted RF energy, ESD, power surges, or electrical fast transients (EFT).

EMISIforDataCenters, a leading B2B provider across North America, helps organizations proactively reduce system vulnerabilities and achieve regulatory compliance. By leveraging cutting-edge solutions, we offer structured immunity and susceptibility testing frameworks tailored for sectors where electromagnetic compatibility (EMC) is mission-critical. Businesses gain the insights they need to validate performance, increase product reliability, and accelerate time-to-market while meeting U.S. and Canadian EMC standards.

Case Study

United State

Case Study 1: Electronics Startup Reduces Certification Delays

A Tier 4 data center in Chicago implemented EMISIforDataCenters’ immunity testing strategy after experiencing data loss during RF exposure events. Utilizing GAO Tek’s portable conducted immunity testers and ESD simulators, the facility identified and hardened susceptible power distribution units and high-speed data interconnects. Post-upgrade audits showed a 92% drop in incident reports related to electromagnetic disturbances.

United State

U.S. Case Study 2: Aerospace Control Systems EMC Qualification

A defense contractor in Florida engaged EMISIforDataCenters to validate its aircraft control units under strict EMC conditions. Using radiated field immunity test setups from GAO Tek, systems were subjected to 10 V/m field strength across 80 MHz–2 GHz. We supported automated test cycles and delivered full compliance documentation to MIL-STD-461G requirements, enabling rapid program certification.

Canadian Case Study: Telecom Infrastructure Immunity Audit

A major telecom provider in Ontario faced recurring signal degradation during equipment rollouts. EMISIforDataCenters deployed GAO RFID monitoring sensors combined with ESD and EFT simulation tools from GAO Tek. Within weeks, we helped reconfigure the grounding and shielding of critical subsystems, ensuring full ICES-003 and IEC 61000 compliance.
