The purpose of this document is to provide guidelines for the use of automatic test equipment (ATE) for the measurement of electromagnetic emissions of electronic, electrical, and electro-mechanical equipment. It is intended to be a companion document to ANSI C63.2-19961 and ANSI C63.4-2003 for making accurate and repeatable automated emissions measurements from 9 kHz to 1 GHz according to commercial Electromagnetic Interference (EMI) regulations. As such, it addresses automated measurement… read more processes, automatic test equipment, and measurement integrity aspects. Furthermore, the importance of a test plan will be outlined. Although intended for automatic testing, these guidelines also apply to semiautomatic measurements where only parts of a test may be automated. read less

FM and television broadcast receivers are frequently potential sources of interference to other FM and television broadcast receivers as well as to receivers in other services. In the range of 300 kc to 25 Mc, this interference can arise from high-level receiver signals such as the IF and, in television receivers, the horizontal deflection system. This standard defines a method for obtaining a measure of the interference conducted by the power line from these various interference sources in the… read more frequency range of 300 kc to 25 Mc. It supersedes and replaces the following three standards: IRE Standards on Receivers: Methods of Measurement of Interference Output of Television Receivers in the Range of 300 to 10,000 kc, 1954 (54 IRE 17.S1), IRE Standards on Methods of Measurement of the Conducted Interference Output of Broadcast and Television Receivers in the Runge of 300 kc to 25 Mc, 1956 (56 IRE 27.S1), and 'Supplement to IRE Standards on Receivers: Methods of Measurement of Interference Output of Television Receivers in the Range of 300 to 10,000 kc, 1954 (54 IRE 17. SI) (58 IRE 27. SI). This standard describes standard input signals, the equipment set-up and measurement techniques. read less

This recommended practice describes a procedure that electric utility companies and others may use to respond to reports of interference to radio and/or television reception. It describes procedures to determine if a reported noise is harmful interference to a licensed radio service. It describes modern noise-locating techniques and equipment and protocols that use time-domain noise signatures to investigate and identify radio noise in the field.

This standard establishes interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of replaceable electronic modules. Such equipment is used only as an integral part of other subsystems or systems, and may not be used independently. This standard is best suited for items that have the following features: removable/replaceable electronic circuit card modules that plug into an equipment rack or frame, with… read more electrical interconnections primarily through edge connectors that interface directly with a backplane, and electrical power input derived from the backplane power sources. This standard should not be directly applied to equipment that can be used independently as a stand-alone system or subsystem (separate box intra-connected by a wire harness to other boxes of a subsystem), or to entire system platforms. It is assumed that the rack/frame equipment with its full complement of REMs is tested in some configuration to an equipment EMI standard such as MIL-STD-461E. This standard is best suited for situations where the qualification of the REM is more effective than requalification of the rack/frame equipment with the new REM. read less

This recommended practice establishes appropriate electromagnetic (EM) threat levels, protection methods, monitoring techniques, and test techniques for specific classes of computer equipment. This equipment is expected to be accessible to the public at ranges less than 100 m, and the loss of operation of the equipment due to intentional electromagnetic interference (IEMI) is expected to cause losses (both financial and of confidence) to businesses operating computer equipment, which are… read more providing services to the public or to private companies. The principle class of equipment to be considered in this recommended practice includes fixed (non-mobile) computer equipment. Examples include automated teller machines (ATMs); electronic cash registers at stores; computer equipment in banks and at airports; computer equipment controlling traffic flow; computer equipment controlling communications or allowing Internet access; computer equipment providing police, fire, and security services; computer equipment controlling the operation of the power grid (including smart meters); computer equipment operating in hospitals; etc. read less

This guide identifies the mechanisms and analytical approach for ac interference effects on conductive linear facilities due to the operation of co-located electric transmission lines. The common mechanisms for ac interference, including magnetic inductive coupling, capacitive coupling, and conductive voltage transfer through soil are discussed. Included are general guidelines and considerations for performing detailed ac interference analyses, with sections specific to the analysis of co-… read more located pipeline and railroad facilities. This guide does not dictate specific compliance limits, direct when an ac interference analysis must be performed, or cover other issues that may need to be considered in joint-use corridors, such as effects due to lightning striking the line or dc corrosion on structures. read less
