Arcade manufacturers conduct rigorous electromagnetic interference (EMI) testing to ensure their products meet international regulatory standards and prevent disruptions to other electronic devices. This process begins during the design phase with proper shielding, grounding, and component layout to minimize EMI emissions. Manufacturers use specialized testing chambers equipped with spectrum analyzers and antennas to measure radiated and conducted emissions across frequency ranges. Products are tested under operational conditions simulating actual arcade environments, with engineers checking for emissions that exceed limits set by regulations such as the FCC Part 15 in the United States and CISPR standards internationally. Additionally, manufacturers perform immunity testing to ensure arcade machines can withstand external EMI from other devices. Failed units undergo redesign with additional shielding, ferrite beads, or filter circuits before retesting. This comprehensive testing process guarantees that arcade games operate reliably without interfering with nearby electronics while maintaining their own performance stability in electrically noisy environments.
