The Schaffner NSG 432 is a classic, handheld electrostatic discharge (ESD) simulator designed for testing electronic equipment's electromagnetic compatibility (EMC) against ESD events. Capable of generating air discharges up to 25 kV, it features a modular design with interchangeable RC networks to comply with early and modern testing standards such as IEC 801-2 and IEC 1000-4-2.
