Compliance testing to EMI / EMC specifications is performed in a laboratory environment. Most clients require an EMI control plan to start the EMI test process.

Test plans are written for the EMC tests before the initiation of compliance testing. After the customer/client approves the test plan, the equipment begins the test process. HCT America Engineering provides complete testing solutions as well as formal test reports required by the purchasing agencies of the government.

HCT America Engineering Military / Aerospace Compliance Testing

//

Equipment intended for use in the Military and Aerospace sectors must be tested for compliance with various standards, such as MIL-STD 461 / 462 EMI / EMC specifications, RTCA DO-160G, and Space Station SSP 30328. HCT America Engineering has extensive experience with these standards going back to the establishment of the company as HCT America Engineering in 1970 (Fremont, California).

Emissions testing to 18 GHz electric radiated fields, as well as conducted emissions on power mains and interconnect lines are measured from the equipment under test while configured in a typical system configuration. Various conducted susceptibility tests, including Radiated Susceptibility to 18 GHz and 100 V/M, are performed on the equipment under test as dictated by its intended operational environment.

HCT America Engineering has collected the most extensive variety MIL-STD specific test equipment in the Bay Area. We offer consultation on Test Plan design, as well as failure mitigation. Contact Bob Cole at 510-405-5172 to discuss your MIL-STD or Aerospace requirements. We have worked with clients such as Lockheed Missiles and Space, EDO RSS, CPU Technology, and UC Berkeley Space Sciences Lab to deliver test results in an expedited manner for US Navy, NASA, and DoD. As well as various Space Shuttle payload projects for NASA Ames Research.

STANDARD

DESCRIPTION

RTCA DO-160D/E/F/G RTCA DO-160D/E/F is published by RTCA, Inc.; manufacturers of commercial avionics equipment selling products in the United States, Europe, and around the globe must meet RTCA requirements
MIL-STD-461C/D/E/F/G MIL-STD-461C/D/E/F establishes the design requirements for the control of the electromagnetic emission and susceptibility characteristics of equipment and subsystems used by agencies of the U.S. Department of Defense
EUROCAE/ED-14D EUROCAE/ED-14D is the European Union version of RTCA DO-160D
Def-Stan 59-41 Def-Stan 59-41 is the United Kingdom’s Ministry of Defense EMC standard, similar to MIL-STD-461

1.5M MIL-STD 461 Semi-Anechoic Chamber

Our Regulatory Compliance Test Lab has over 35 years of history in the Silicon Valley as a premier provider of MIL-STD Compliance testing. Our Semi-Anechoic Chamber and control rooms were specifically designed to meet MIL STD 461 specifications.

For the purpose of comparison, full anechoic chambers are designed for unidirectional energy absorption.

Semi-anechoic chambers have a solid floor that provides a work surface for supporting Equipment Under Test (EUT’s), such as rack systems, large equipment, or motorized vehicles; Rather than the raised floor or grille over absorbent tiles, found in full anechoic chambers. This floor is part of the chamber (Faraday Cage) blocking unwanted, ambient, RF signals. Absorbers may be placed on the floor during certain emissions and immunity tests.HCT America Engineering's MIL-STD chamber is designed to meet these requirements:

Typical frequency range: 10 Hz - 40GHz. Military standards will vary from country to country but are often quite similar. Chamber requirements are typically set by the particular standard. MIL-STD semi-anechoic chamber requirements are significantly different than those designed for commercial product standards.HCT America Engineering was established as a MIL-STD testing facility in 1975. We have since expanded into the commercial and industrial EMI/EMC testing markets.
