Military Systems and Components Testing

As recognized testing partner IB-Lenhardt AG provides design and delivering of EMC and RF testing programmes for your communications and short range radar systems. You benefit from our support from the initial test plan development on through the final test reporting.

Military Defense Industry

Accredited EMC and RF Testing Services

The armament and defense industry produces more and more high-tech components and systems such as software defined portable radios, drones, fusion goggles as well as radio remote ignition systems and tactical on-board radios, that must be able to withstand the highest levels of stress and be absolutely accurate, reliable and secure in the field. This is accompanied by highest demands on development, verification and testing of the military defense equipment.

In order to avoid risks from special influences from the military environment for the safety and operation of tactical communication and radar systems, complex procedures are used in the testing of military defense systems, to ensure that the characteristics of these radiocommunication systems are within the limits of the standard.

Defense Communication Equipment

Robustness and reliability are key requirements for military, tactical and law enforcement radios.

Voice and Data Communication

Electromagnetic Compatibility Testing

EMC Testing for the Military Defense Industry

As your reliable partner for electromagnetic compatibility (EMC) testing, IB-Lenhardt AG and its subsidiary IBL-Lab GmbH offer comprehensive EMC testing according to military standards to meet the requirements for military communication systems and components at an early stage of development.

The analysis of emissions and immunity provides information about the potentially unwanted propagation and reception of electromagnetic energy and high-frequency interference. EMC testing is mandatory to ensure electromagnetic compatibility of components and mitigate vulnerability to outside sources.

You can be sure that your project is in the best hands with us - with our many years of experience and comprehensive EMC testing know-how, we support you from the very beginning.

Radio Frequency Testing

High-End Military Radio Equipment

Instruments used in tactical communications radio segments are required to cover a wide range of applications and complex technologies. Testing these high-end military radio equipment requires know-how, high-quality equipment and competent engineers to verify single analog and digital components.

Performing MIL-STD testing for suppliers of military systems, sub-systems, and components includes among others interoperability and coexistence tests. With the measurement solutions from Rohde & Schwarz we offer the highest performance and reliability.

IB-Lenhardt AG and IBL-Lab GmbH enable radio frequency qualification according to international standards, and customization for private or national security standards.


European and International Military Standards

DEF-STAN 59-41

The requirements of this Standard apply to the limitation of propagated electromagnetic energy, whether conducted or radiated, and to the limitation of the susceptibility of electrical and electronic equipment, sub-systems and systems to such energy.

DEF-STAN 59-411

This Standard outlines the typical electromagnetic environmental requirements for electrical/electronic equipment used in the Services and guidance is given covering documentation which ensures management and control procedures are implemented during all acquisition stages of any given project.


Requirements for the control of Electromagnetic Interference Characteristics of Subsystems and Equipment (11-DEC-2015): This standard 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 Department of Defense (DoD). Such equipment and subsystems may be used independently or as an integral part of other subsystems or systems. 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, and electrical power input derived from prime power sources. This standard should not be directly applied to items such as modules located inside electronic enclosures or entire platforms. The principles in this standard may be useful as a basis for developing suitable requirements for those applications. Data item requirements are also included.


Measurement of Electromagnetic Interference Characteristics (11 JAN 1993) [S/S BY MIL-STD-461E]: This standard establishes techniques to be used for the measurement and determination of the electromagnetic interference characteristics (emission and susceptibility) of electrical, electronic, and electromechanical equipment, as required by MIL-STD-461


Electromagnetic Environmental Effects, Requirements for Systems (01 DEC 2010): This standard establishes electromagnetic environmental effects (E3) interface requirements and verification criteria for airborne, sea, space, and ground systems, including associated ordnance.


Aircraft Electric Power Characteristics (12 MAR 2004): This standard establishes the requirements and characteristics of aircraft electric power provided at the input terminals of electric utilization equipment. MIL-HDBK-704-1 through-8 defines test methods and procedures for determining airborne utilization equipment compliance with the electric power characteristics requirements defined herein. Electromagnetic interference and voltage spikes are not covered by this standard.


Environmental Engineering Considerations and Laboratory Tests (31-JAN-2019) (65 MB): This Standard contains materiel acquisition program planning and engineering direction for considering the influences that environmental stresses have on materiel throughout all phases of its service life. It is important to note that this document does not impose design or test specifications. Rather, it describes the environmental tailoring process that results in realistic materiel designs and test methods based on materiel system performance requirements. Figure 1-1 summarizes this direction.


Characteristics of 28 Volt DC Electrical Systems in Military Vehicles (22-MAR-2013): This standard covers the limits of transient voltage characteristics and steady state limits of the 28 volt (V) direct current (dc) electric power circuits of military vehicles.
