VG 96903 Conducted Immunity to NEMP

Montena develops and manufactures high voltage pulse generators for NEMP (Nuclear Electromagnetic Pulse) / HEMP tests according to the standards DIN VG 96903-70, VG 96903-78, VG 96903-79 and VG 96903-80.

Part 70: Galvanic injection of NEMP disturbing quantities into cable terminals and cable shields of equipment

Part 78: Direct injection of NEMP disturbing quantities to cables and cable harnesses of multi-application equipment

Part 79: Testing of Multi-application Protective Devices (MAPD) for Immunity to NEMP Interference

Part 80: Testing of antenna terminals against NEMP and lightning interference.

All generators have a remote control unit providing indications and settings of the charging voltage and pulse triggering as well as an interlock switch for safety. USB and RS232 interfaces are available for control software applications.


  • Compact and robust construction
  • Complete set of accessories for test and measurement

Montena design can be adapted to customers’ requirements to fulfil other standards.
