IEEE 2718-2023

IEEE 2718-2023 is a technical guide for near field characterization of unintentional stochastic radiators, helping engineers describe and evaluate electromagnetic behavior close to the source. In the context of fields, waves, and electromagnetics, it supports more consistent measurement and interpretation of emissions that may not be fully predictable. This can be useful when comparing test results, improving repeatability, and reducing uncertainty in near-field assessments for complex electrical systems.

Overview of IEEE 2718-2023

This standard focuses on methods and considerations for characterizing unintentional stochastic radiators in the near field, where electromagnetic fields can vary significantly with position. IEEE 2718-2023 is relevant to measurement planning, data interpretation, and the technical language used to describe stochastic emission behavior. It is aimed at situations where conventional far-field assumptions may not adequately represent the source, making near-field analysis important for accurate engineering evaluation and documentation.

Typical use cases

IEEE 2718-2023 may be used when assessing electronic devices, assemblies, or subsystems that produce unintended electromagnetic emissions with variable behavior. It is particularly relevant for near-field measurement setups, lab characterization work, prototype evaluation, and troubleshooting of complex equipment where source behavior is not easily repeatable. The guide can also support work involving antennas, probes, instrumentation, and other electromagnetics test arrangements used to observe localized field patterns.

Why it matters

For engineering teams, IEEE 2718-2023 helps improve consistency in how near-field emissions are characterized and communicated. That matters when comparing test results across labs, supporting design decisions, and reducing the risk of misinterpreting stochastic behavior as a stable signature. By offering a common technical basis, the standard can aid compliance efforts, refine test practices, and support more reliable procurement and performance review for systems with unintentional electromagnetic emissions.
