IEEE C63.2-2023

C63.2-2023 is an American National Standard for electromagnetic interference and field strength measuring instrumentation used in the 9 kHz to 40 GHz range. It defines technical expectations for measurement equipment and related performance characteristics, helping users obtain more consistent results across a wide span of frequencies. For engineers working in fields, waves, and electromagnetics, this standard supports more reliable testing, comparison, and compliance-focused instrumentation selection.

C63.2-2023 overview

This standard addresses the specifications that apply to instrumentation used for measuring electromagnetic interference and field strength across low-frequency through microwave ranges. In practical terms, C63.2-2023 helps establish a clearer basis for how measuring devices should perform when evaluating emissions, field levels, and related electromagnetic conditions. The document is especially relevant where measurement accuracy, repeatability, and defined instrument behavior are important to technical assessments and conformity work.

Typical use cases

C63.2-2023 is commonly used when selecting or evaluating instruments for EMI measurements, field-strength surveys, and laboratory or site testing over the 9 kHz to 40 GHz range. It is relevant to test benches, calibration activities, receiver and antenna-based measurement setups, and other workflows that depend on controlled instrumentation performance. Organizations involved in electromagnetic compatibility work, power and energy systems, and applied RF engineering may use it to support consistent measurement practice.

Why this standard matters

Clear instrumentation requirements help reduce measurement ambiguity, especially when results are used for compliance decisions or engineering comparisons. C63.2-2023 supports better procurement, testing consistency, and design control by giving users a defined technical reference for EMI and field-strength measurement equipment. That can lower the risk of mismatched instruments, improve repeatability between test environments, and make it easier to compare data gathered by different teams or facilities. For regulated or quality-driven work, that consistency is valuable.
