Modern computers operate in a "noisy" electromagnetic environment, with interference created by radio and radar equipment, microwave transmitters, other computers, and various electronic devices. On top of this, computers in systems environments such as vehicles or containers have to manage extraordinary levels of interference (irradiation/emission) generated by the device itself as well as other military equipment, such as IED jammers. In recent years, in the context of networked operations management, protection against electromagnetic interference has gained tremendous importance.
EMC requirements vary widely from one application to the other (e.g., land vehicles versus aircrafts) and even within specific application cases (e.g., on-deck and below-deck on naval ships). The MIL-STD 461 standard therefore specifies a wide range of requirements for an equally wide variety of environments.
Many applications only require compliance with "commercial" EMC standards, which is why roda computer offers customers the option of dispensing with further modifications to cut costs on the selected platform; however, it is important to note that most military applications require a high level of protection against EMC interference.
Therefore, roda computer takes the EMC properties of its products very seriously. In addition to certifications by an independent laboratory, regular product tests are carried out in an in-house test environment.
