Pulsed Current Injection
MIL-STD-188-125 PCI

Fixed and mobile ground-based mission critical C4I systems (command, control, communications, computer, and intelligence) require full functionality and network interoperability during and after exposure to HEMP environments. Hardening requirements include stringent shielding, electrical POE (Point Of Entry) protection and special protective measures.

Montena has developed a full range of pulse generators according to MIL-STD -188-125-1 & 2. This standard describes the pulsed current injection (PCI) tests, simulating the currents induced in cables exposed to NEMP pulses. The systems provided cover the short pulse (E1), intermediate (E2) and long pulse (E3) tests. A charge line pulser is also available for antenna line testing. Accessories such as current injection and measuring probes, coupling and decoupling networks, fiber optic links, etc.. are delivered with the equipment. A PC software application drives all the instruments for a simple and effective operation.


  • Unique fully compliant test solution to cover the entire standard requirements
  • Transportable for on-site verification tests
  • Control and pulse management software package to simplify the test procedure
