MIL-STD-461G 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. 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.

 

Required Test Equipment:


Pulse generator, 50 ohm, charged line (coaxial)
• Current injection probe
• Drive cable, 50 ohm, 2 meters, 0.5 dB or less insertion loss at 500 MHz
• Current probe
• Calibration fixture: coaxial transmission line with 50 ohm characteristic impedance, coaxial connections on both ends, and              space for an injection probe around the center conductor.
• Oscilloscope, 50 ohm input impedance
• Attenuators, 50 ohm
• Coaxial loads, 50 ohm
• LISNs
