MIL STD 461F Training

The MIL-STD-461F standard (upgraded to MIL-STD-461G) establishes interface and associated verification requirements for the control of the electromagnetic interference (EMI) emission and susceptibility characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use by activities and agencies of the DoD.

MIL-STD-461 contains about 20 test parameters, of which 10-12 are relevant for the majority of the products. The standard is very systematic, with set terms for the different test parameters.

All emission test parameters have E as the last letter. For example: RE – Radiated Emission for all radiated emission tests. Likewise, immunity parameters are referred to with an S for Susceptibility, which is the standard’s term for vulnerability. Susceptibility is the inverse expression for immunity. For example: Conducted Susceptibility for conducted immunity tests. In addition, the tests have 3-digit serial numbers.

Experts in this field report that MIL-STD-461 testing is important for safety and mission success. Space-constrained programs and applications that utilize numerous embedded computer systems are growing in number which means the propensity for EMI between them is growing as well.

MIL-STD-461 is a tried-and-true electromagnetic testing standard dating back as far as 1967, when the DoD first issued the document to establish EM compatibility requirements for defense technology as parts of its Electromagnetic Compatibility Program.

In general, the MIL-STD-461 document is applied to electrical or electronic systems such as rugged servers and workstations used in military programs and applications.

An MIL-STD-461 certification ensures that a system doesn’t suffer from EM interference or disrupt other devices near it.

Each MIL-STD-461 requirement is identified by three-digit number succeeding a two-letter combination. For example:

  • Conducted emissionsrequirements are designated by CE
  • Radiated emissionsrequirements are designated by RE
  • Conducted susceptibilityrequirements are designated by CS
  • Radiated susceptibilityrequirements are designated by RS

Conducted emissions refer to EM energy generated by a system or device and transmitted through its power cord via an electric current.

This standard is best suited for items that have the following features:

  • Electronic enclosures that are no larger than an equipment rack
  • Electrical interconnections that are discrete wiring harnesses between enclosures
  • Electrical power input derived from prime power sources

However, this standard is not directly applied to items such as modules located inside electronic enclosures or entire platforms. But the principles in this standard may be useful as a basis for developing suitable requirements for those applications.

Data item requirements are also included.

MIL STD 461F Training Course Description

MIL STD 461F training provides the information and skills required to implement MIL-STD 461F. This standard regulates boundary and relevant verification criteria for the regulation of the electromagnetic interference (EMI) emission and vulnerability features of electronic, electrical, and electromechanical instruments and subsystems planned or acquired for application by actions and organizations of the Department of Defense (DoD). The stated equipment and subsystems could be applied individually or as a joint sector of other subsystems or systems.

New updates on MIL-STD-461G has been added to the course. The MIL STD Revision G (MIL-STD-461G) has affected several existing tests, procedures and testing methodology, as well as adding new tests and test procedures not referenced in the past and previous specs.

MIL STD 461F Training

MIL STD 461F is perfect for elements possessing the following features: electronic enclosures that are no greater than an equipment rack, electrical interconnections that are distinct wiring harnesses between enclosures, and electrical power input originated from major power sources. This standard should not be directly used for the items such as modules placed within electronic enclosures or the whole platforms. The rules in this standard may be valuable as a foundation for emerging appropriate criteria for those applications. Data item requirements are also discussed.

TONEX Training Format

MIL STD 461F training will be delivered as a combination of both theory and practice. Students will learn about the theory of this standard via lectures and presentations. Each module is followed by practical activities including labs, small/group activities, and hands-on workshops.
