Ametek OCS 500N6.1

The Ametek OCS 500N6.1 is an EMC test instrument that generates damped oscillatory waves and ring waves to evaluate the electromagnetic compatibility of electronic equipment. It simulates transient disturbances on power, control, and signal lines, assessing device robustness under electrical stress conditions. The instrument supports testing per IEC 61000-4-18, IEC 61000-4-12, ANSI/IEEE C62.41, and IEC 61000-4-10 standards, making it essential for laboratory, industrial, and research environments requiring rigorous EMC validation.
