Military EMC Testing

MET’s Military EMC Testing capabilities and experience are unmatched in North America. On both coasts, MET Labs performs 200 V/m Radiated Immunity test requirements per MIL-STD-461 and RTCA DO-160 in-house.

Military EMC TestingMET Laboratories provides accurate and repeatable military EMC test results due to:

  • Knowledgable and experienced personnel following a well-designed process
  • The use of “State-of-the-Art” test equipment

Every test engineer at MET Laboratories utilizes the latest in advanced test equipment: RF Shielded enclosures, Digital Phosphorus Oscilloscopes, Radio Frequency (RF) Signal Generators, High Power RF Amplifiers (200V/m), Rhode & Swartz and Agilent PSA Series Spectrum Analyzers, Transient Generators, Power Generators, Test Antenna Systems, and Environmental Simulation Test Equipment.

MET has designed and constructed custom Hemholtz Coils for magnetic immunity testing. The system is capable of generating magnetic fields from DC to 100kHz in excess of 180 dBpT. These fields exceed requirements for Army/Navy RS101, DoD-STD 1399 (pt.070), RTCA DO-160 and various ANSI and European specifications.

This equipment is utilized in our 3 meter, 5 meter and 10 meter ambient-free chambers on both coasts. MET also utilizes a state-of-the-art reverberation chamber that generates 27,000 V/m from 80 MHz to 18 GHz.

Following are the military EMC tests that MET Labs is accredited to perform for top military defense contractors:

MIL-STD-461/462 including all test methods:

  • Conducted emissions: CE101, CE102, CE106
  • Conducted susceptibility: CS101, CS103, CS104, CS105, CS106 CS109, CS114, CS115, CS116
  • Radiated emissions: RE101, RE102, RE103 (up to 40 GHz)
  • Radiated susceptibility: RS101, RS103 (200 V/m up to 40 GHz), RS105 (50,000 V/m)

Note: MIL-STD-461 emission test limits are 20 times more stringent than FCC limits, and as a result, can be difficult for manufactures to obtain MIL-STD compliance. If needed for EMC compliance, our Test Engineers, who are skilled at debugging, can offer ‘real-time’ technical assistance to modify your product’s electrical or mechanical interface to meet the stringent emission or susceptibility MIL-STD test limits.
