ESD simulator features common discharge networks

The NSG 438 simulation system group includes 150pF/330ohm, 150pF/2kohm, 330pF/2kohm and 330pF/330ohm discharge networks.

The NSG 438 ESD simulation system group fulfills many automotive and industry test standard requirements including ISO 10605.

With over 20 optional discharge networks, the simulation system also meets several other industry test standard requirements including IEC, ANSI and SAE.

The NSG 438 contains pre-programmed settings for IEC/EN 61000-4-2 and ISO 10605 to ensure the simulator is set up correctly and the proper discharge network is installed.

The simulator's built-in ISO calibration self-test feature saves time by eliminating extra calibration and functional measurements prior to starting a test procedure.

In addition, the NSG 438 meets the proposed new requirements indicated by ANSI and IEC, which require a more precise definition of calibration methods and tighter specifications for pulse parameters.

With a wide range of discharge networks and rigid and flexible tips available, the simulator meets diverse applications in the automotive, consumer electronics, telecommunications, medical, aerospace and defence industries.

The NSG 438 features pulse voltages of up to 30kV, which support demanding research and development test procedures to determine immunity limits.

The simulator offers adjustable pulse repetition rate ranges from 0.04s to 300s.

A random generator function is also provided for non-standard interference immunity tests, in which the controlled statistical repetition rate of pulse triggering is programmed in either pulse or time mode.

To enable accurate discharge detection and to eliminate faulty discharge counts over a wider operating voltage range, the NSG 438 contains variable threshold selection.

Useful for long test runs, the counter or present counter is incremented or decremented when a discharge is detected.

In addition, the detection feature can be switched off when testing EUTs with non-conductive surfaces, such as plastic housings.

Users can create and store test conditions in the instrument's memory, resulting in retrieval of the settings remaining on the menu prior to shutdown as well as saved test conditions.

With a safety interlock, the simulator can only be activated as a result of an intentional action by the user; otherwise it switches off automatically for safety purposes.

The NSG 438 is powered by a high-energy battery pack for prolonged performance.

The group, like the base model, comes with a traceable calibration certificate and two-year warranty.
