Electrostatic Discharge (ESD) tests are used to verify complete systems and duplicate disturbances in installations. These tests contribute to identify immunity failures caused by bad cabling or system composition, as well as grounding problems. Teseq’s ESD simulators fulfill the requirements of all major ESD standards. Thanks to stabilized HV output all Teseq simulators exceed this need by far and guarantee optimized reproducibility of tests. The basic models are type-approved and calibrated to IEC/EN 61000-4-2. A comprehensive range of additional network modules are available for testing to various standards including ISO 10605.
