Services
EMC Testing
EMC Testing ensures devices meet electromagnetic compatibility standards, preventing interference in Aerospace, Defense, and Commercial applications. Our ISO/IEC 17025-accredited labs use advanced systems for compliance with FCC, CE, and MIL-STD requirements. Clients benefit from tailored solutions for radiated and conducted emissions, ensuring product reliability in complex environments.
Lightning Testing
Lightning Testing evaluates equipment resilience to direct and indirect lightning effects, critical for Aerospace and Defense systems. Our Anaheim facility features custom waveform generators and a 32x64-foot ground plane for high-voltage testing. Clients receive precise certification to RTCA DO-160 and MIL-STD-464 standards, ensuring safety and compliance for aircraft and ground systems.
Environmental Testing
Environmental Testing assesses product performance under extreme conditions like vibration, temperature, and humidity. We test to MIL-STD-810 and RTCA/DO-160 standards for Aerospace, Automotive, and Medical industries. Our facilities simulate real-world stresses, including thermal shock and acoustic noise, ensuring durability and regulatory compliance for global markets.
HIRF Testing
HIRF Testing validates aircraft systems against high-intensity radiated fields using RF Reverberation Chambers. Our labs achieve field strengths up to 25,000V/m, meeting RTCA DO-160G and MIL-STD-464 requirements. Clients gain certification for avionics and flight control systems, ensuring operational safety in high-frequency environments through automated, real-time data monitoring.
Product Safety Testing
Product Safety Testing ensures compliance with FCC, UL, CE, and CSA standards for Consumer, Medical, and Industrial equipment. We conduct ESD, shielding effectiveness, and radiated susceptibility tests to 62368 and 60601-1 standards. Clients receive comprehensive consulting to address safety and regulatory challenges, streamlining global market access for electronic devices.
