MIL-STD-461E  Overview - eEngineer


MIL-STD-461E: DOD Interface Standard Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment (August 20, 1999)

Consolidates MIL-STD-461D and MIL-STD-462D into one Standard. EUT hardware and software must be representative of production. Susceptibility scan rates and the frequency of measurement system test checks were revised.

Conducted Emissions

CE101: is no longer applicable to shipboard equipment

CE101: 30 Hz - 10 kHz (Power Leads)
CE102: 10 kHz - 10 MHz (Power Leads)
CE106: 10 kHz - 40 GHz (Antenna Terminals)

Conducted Susceptibility

CS101: applicability and limits were extended to 150 kHz
CS109: measurement procedures were revised
CS114: limits were revised
CS115: applicability was revised for several equipment classes
CS116: measurement procedures were revised; applicability was revised for several equipment classes

CS101: 30 Hz - 150 kHz (Power Leads)
CS103: 15 kHz - 10 GHz (Ant Port Intermod)
CS104: 30 Hz - 20 GHz (Ant Port Rejection of Undesired Signals)
CS105: 30 Hz - 20 GHz (Ant Port Cross Modulation)
CS109: 60 Hz - 100 kHz (Structure Current)
CS114: 10 kHz - 200 MHz (Bulk Cable Injection)
CS115: Spikes, Impulse (Bulk Cable Injection)
CS116: 10 kHz - 100 MHz (Sinusoidal Transients - Cables & Power Leads)

Radiated Emissions

RE101: the 50 cm requirement was deleted; limits are more stringent
RE102: limits were revised for submarine equipment

RE101: 30 Hz - 100 kHz (Magnetic Field)
RE102: 10 kHz - 18 GHz (Electric Field)
RE103: 10 kHz - 40 GHz (Antenna Spurious & Harmonics)

Radiated Susceptibility

RS101: limits were revised for Navy applications; added an alternative test using the Helmholtz coil
RS103: added use of mode-tuned reverberation chambers above 200 MHz
RS105: limits were revised for consistency with IEC Standards

RS101: 30 Hz - 100 kHz (Magnetic Field - Equipment & Cables
RS103: 2 MHz - 40 GHz (1000 Hz Square Wave Mod; Electric Field - Equipt & Cables)
RS105: Electromagnetic Field Transients
