MIL-STD-461 CS118

CS118 is a standard under the subcategory of conducted susceptibility within the umbrella standard of MIL-STD-461. This standard applies to electrical, electronic, and electromechanical subsystems and equipment that have a man-machine interface. Equipment that interfaces with or controls ordnance items are not included in this standard. The purpose of CS118 is to establish the ability of the equipment under test (EUT) to withstand personnel borne electrostatic discharge (ESD) in a powered-up configuration.

Test equipment needed for CS118 requirements:

• ESD Generator, adjustable from ±2kV to ±15kV (minimum range), and Table X for simplified ESD generator characteristics.
• ESD network, 150 picofarads (pF) capacitance (330 ohm) discharge resistance.
• Contact discharge tip Figure CS118-2.
• Air discharge tip Figure CS118-2.
• Electrostatic voltmeter.
• Oscilloscope, single event bandwidth ≥ 1 GHz.
• ESD current target, input resistance 2 ±5% ohms, Figure CS118-3.
• Attenuator, 20 dB.
• Coaxial cable (50 ohm) impedance, ≤ 1 meter.
• Metallic ground plane.
• Ionizer or one (1) megohm resistor (1MΩ±10%).
