MIL-STD 461 CS115

DEPARTMENT OF DEFENSE INTERFACE STANDARD

MIL-STD 461 CS115 Conducted Susceptibility, Bulk Cable Injection, Impulse Excitation

This test procedure is used to verify the ability of the EUT to withstand impulse signals coupled onto EUT associated cabling.

Applicability

This requirement is applicable to all aircraft, space, and ground system interconnecting cables, including power cables. The requirement is also applicable for surface ship and submarine subsystems and equipment when specified by the procuring activity.

Limit

The EUT shall not exhibit any malfunction, degradation of performance, or deviation from specified indications, beyond the tolerances indicated in the individual equipment or subsystems specification, when subjected to a pre-calibrated signal having rise and fall times, pulse width, and amplitude as specified on Figure CS115-1 at a 30 Hz rate for one minute.
