IEEE C37.90.1-2012 Compliant Damped-Oscillatory Wave Simulator

Damped Oscillatory Wave Simulator (SWCS) IEEE C37.90.1-2012 Compliant Damped-Oscillatory Wave Simulator

This simulator generates high-frequency noise with a fast repetition rate that occurs when switches and other switching devices are turned ON/OFF, simulating the noise to evaluate the immunity of electronic and electrical equipment.
It can perform tests compliant with IEC 61000-4-18 (2006), the power standard B-402 (2007), and the IEEE C37.90-2012 standard.
