European EMC test house Teseq has introduced a new ESD simulator, dubbed the NSG 438A, that includes an integrated discharge relay circuit to dissipate residual voltage in conventional ESD testing and ungrounded equipment under test (EUT) applications.

The relay in the new simulator provides unique controlled and reproducible discharge and observation time periods along with a discharge operation that is programmable in three separate time segments. It can also be retrofitted into any existing Teseq NSG 438 or NSG 439. By connecting a 1M? resistor from the EUT to ground for a controlled time segment that dissipates the residual voltage, the NSG 438A has set new benchmarks in flexibility and reproducibility of EMC testing.
