Military EMC Tests
Electromagnetic compatibility tests for military devices and systems according to the MIL-STD-461 standard. Mandatory tests for the acceptance of military devices.
Electromagnetic Compatibility (EMC/EMI)
Defined as the ability of a device, equipment, or system unit to operate in its own electromagnetic environment without causing electromagnetic distortion beyond tolerance to this environment and without being affected by a certain level of electromagnetic distortion.
Critical: EMC/EMI is one of the most important features that must be provided for military devices, and the acceptance of a military device that fails EMC/EMI tests cannot be completed.
MIL-STD-461 Standard
The fundamental standard for military electromagnetic compatibility tests at the device and subsystem level.
All Platforms
The only standard applicable to all military applications, including air, sea, and land platforms.
Standard Development Process
First EMC/EMI studies began
MIL-STD-461, 462, and 463 were published
MIL-STD-462 was merged with MIL-STD-461
MIL-STD-461 continues to be used as the basic standard
Four Main Test Groups
Electromagnetic tests in MIL-STD-461 are divided into four groups
Radiated Susceptibility
Resistance to electromagnetic signals coming from the external environment
Radiated Emission
Electromagnetic emission made by the device to the external environment
Conducted Emission
Electromagnetic emission conducted through cables
Conducted Susceptibility
Resistance to signals coming through cables
Conducted Emission Tests
Emission tests conducted by the device to the external environment via power and signal cables
Power Leads, 30 Hz - 10 kHz
Power Leads, 10 kHz - 10 MHz
Antenna Terminal, 10 kHz - 40 GHz
Conducted Susceptibility Tests
Resistance tests against unwanted signals coming through power and signal cables
Power Leads, 30 Hz - 150 kHz
Antenna Input, Intermodulation, 15 kHz - 10 GHz
Antenna Input, Rejection of Undesired Signals, 30 Hz - 20 GHz
Antenna Input, Cross-Modulation, 30 Hz - 20 GHz
Transients, Power Leads
Structure Current, 60 Hz - 100 kHz
Cable Injection, 10 kHz - 200 MHz
Cable Injection, Pulse
Damped Sinusoidal Transients, 10 kHz - 100 MHz
Radiated Emission Tests
Electromagnetic emission tests conducted by the device to the external environment via radiation
Magnetic Field, 30 Hz - 100 kHz
Electric Field, 10 kHz - 18 GHz
Antenna Harmonic Outputs, 10 kHz - 40 GHz
Radiated Susceptibility Tests
Resistance tests against unwanted signals coming from the external environment via radiation
Magnetic Field, 30 Hz - 100 kHz
Electric Field, 2 MHz - 40 GHz
Transient Electromagnetic Field
Test Success Criteria
Emission Tests (CE/RE)
The emission made by the device must remain below the limit value given in the standard at every frequency.
Susceptibility Tests (CS/RS)
At every frequency, the electromagnetic signal given at the limit value specified in the standard must not cause degradation in the operation of the device.
