Conducted Susceptibility

MIL STD 461 – Conducted Susceptibility

 

CS101 Conducted Susceptibility – Power Leads, 30 Hz to 150 kHz

This requirement is applicable to equipment and subsystem AC, limited to current draws ≤ 100 amperes per phase, and DC input power leads, not including returns. If the EUT is DC operated, this requirement is applicable over the frequency range of 30 Hz to 150 kHz. If the EUT is AC operated, this requirement is applicable starting from the second harmonic of the EUT power frequency and extending to 150 kHz. This test procedure is used to verify the ability of the EUT to withstand signals coupled onto input power leads.

 

CS103 Conducted Susceptibility – Antenna Port, Intermodulation, 15 kHz to 10 GHz

This receiver front-end susceptibility requirement is applicable to equipment and subsystems, such as communications receivers, RF amplifiers, transceivers, radar receivers, acoustic receivers, and electronic warfare receivers as specified in the individual procurement specification. This test procedure is used to determine the presence of intermodulation products that may be caused by undesired signals at the EUT antenna input terminals.

 

CS104 Conducted Susceptibility – Antenna Port, Rejection of Undesired Signals, 30 Hz to 20 GHz

This receiver front-end susceptibility requirement is applicable to equipment and subsystems, such as communications receivers, RF amplifiers, transceivers, radar receivers, acoustic receivers, and electronic warfare receivers as specified in the individual procurement specification. This test procedure is used to determine the presence of spurious responses that may be caused by undesired signals at the EUT antenna input terminals.

 

CS105 Conducted Susceptibility – Antenna Port, Cross-Modulation, 30 Hz to 20 GHz

This receiver front-end susceptibility requirement is applicable only to receivers that normally process amplitude-modulated RF signals, as specified in the individual procurement specification. This test procedure is used to determine the presence of cross-modulation products that may be caused by undesired signals at the EUT antenna terminals.

 

CS106 Conducted Susceptibility – Transients, Power Leads

This requirement is applicable to submarine and surface ship equipment and subsystem AC and DC input power leads, not including grounds and neutrals.

 

CS109 Conducted Susceptibility – Structure Current, 60 Hz to 100 kHz

This requirement is applicable to equipment and subsystems that have an operating frequency range of 100 kHz or less and an operating sensitivity of 1 μV or less (such as 0.5 μV). Handheld equipment is exempt from this requirement. This procedure is used to verify the ability of the EUT to withstand structure currents.

 

CS114 Conducted Susceptibility – Bulk Cable Injection, 10 kHz to 200 MHz

This requirement is applicable to all interconnecting cables, including power cables. This test procedure is used to verify the ability of the EUT to withstand RF signals coupled onto EUT associated cabling.

 

CS115 Conducted Susceptibility – Bulk Cable Injection, Impulse Excitation

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

 

CS116 Conducted Susceptibility – Damped Sinusoidal Transients, Cables and Power Leads, 10 kHz to 100 MHz

This requirement is applicable to all interconnecting cables, including power cables, and individual high side power leads. Power returns and neutrals need not be tested individually. 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.
