Teseq INA 420

Description 

The Teseq INA 420 is a fast rise time discharge tip developed for use with the NSG 435 electrostatic discharge simulator. It produces a rise time below 400 picoseconds, enabling engineers to apply exceptionally fast transient pulses during diagnostic, development, and susceptibility testing. The accessory replaces the standard discharge tip and extends the NSG 435’s capabilities beyond conventional IEC 61000-4-2 testing. Its sharp pulse characteristics help identify sensitive circuits, evaluate high-frequency responses, and investigate potential weaknesses in electronic equipment, components, and assemblies. Designed for straightforward installation, the INA 420 supports efficient laboratory testing without requiring a separate pulse generator. It is a practical accessory for engineers seeking controlled, repeatable fast transient excitation when troubleshooting designs or assessing electromagnetic immunity performance.
