MIL-STD 461 CS116 Conducted Susceptibility, Damped Sinusoidal Transients, Cables and Power Leads

This test procedure is used to verify the ability of the EUT to withstand damped sinusoidal transients coupled onto EUT associated cables and power leads.

Applicability

This requirement is applicable from 10 kHz to 100 MHz for all interconnecting cables, including power cables, and individual high side power leads. Power returns and neutrals need not be tested individually. For submarine applications, this requirement is applicable only to cables and leads external to or that exit the pressure hull.

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 subsystem specification, when subjected to a signal having the waveform shown on Figure CS116-1 and having a maximum current as specified on Figure CS116-2. The limit is applicable across the entire specified frequency range. Compliance shall be demonstrated at the following frequencies: 0.01, 0.1, 1, 10, 30, and 100 MHz. If there are other frequencies known to be critical to the equipment installation, such as platform resonances, compliance shall also be demonstrated at those frequencies. The test signal repetition rate shall be no greater than one pulse per second and no less than one pulse every two seconds. The pulses shall be applied for a period of five minutes.
