The industry workhouse, the Teseq (Schaffner) NSG 438 30kV ESD simulating gun system is easy to use with a colored touchscreen and easily interchangeable discharge networks. Ergonomic design and advanced functionality. The NSG 438 ESD simulator is designed to sit comfortably in the operator’s hand, with operating conditions constantly displayed and accessible on a bright, clear color touch display.

Teseq NSG 438 Overview:

The NSG 438 comprehensively fulfills virtually all international standard requirements. Based on over 60 optional discharge networks, the NSG 438 can meet any of today’s automotive manufacturers’ standards in addition to these common compliance standards:

  • IEC/EN 61000-4-2
  • ISO 10605
  • EN 61000-6-1
  • EN 61000-6-2
  • RTCA/DO-160 Section 25
  • Mil-STD-461G CS118 (March 2015 Draft)
  • ITU-T K2

The simulator is simple, convenient and safe to use. The whole range of parameter settings including polarity selection, freely adjustable pulse repetition, counter functions and discharge detection is available up to the maximum discharge voltage.

The touch display and keypad for parameter input shows the precise functional and test data with user-selectable language for convenient and safe operation worldwide. The simulator contains variable threshold selection for accurate discharge detection. This detection feature can be switched off when testing EUT’s with non-conductive surfaces, such as plastic housings. Pre-programmed settings for IEC 61000-4-2 and ISO 10605 ensure that the simulator is automatically set up correctly and the appropriate discharge network is installed. The actual RC value is displayed at all times. Molded HV discharge networks in solid cases eliminate ionization and leakage current effects. Precisely tuned combinations of RC components guarantee wave shape parameters to be within tolerances. A unique activity log is included so that the types and numbers of ESD simulations can be easily scrolled through to check what has been tested and in what timeframe.
