Full title and description

Specification for radio disturbance and immunity measuring apparatus and methods — Part 1-5: Radio disturbance and immunity measuring apparatus — Antenna calibration sites and reference test sites for 5 MHz to 18 GHz. This publication is available as CISPR 16-1-5:2014 consolidated with Amendment 1 (2016) — Edition 2.1 (consolidated 16 December 2016).

Abstract

CISPR 16-1-5 defines requirements, specifications and validation procedures for antenna calibration sites (CALTS) and reference test sites (REFTS) used in EMC measurements and antenna calibrations. It covers site geometry and physical characteristics, site validation methods (including site attenuation and antenna factors), uncertainty considerations and criteria for site compliance over the frequency ranges covered (5 MHz to 18 GHz for CALTS/REFTS and 30 MHz to 1 000 MHz for some REFTS uses). The consolidated 2016 edition incorporates the 2014 base publication and the 2016 amendment.

Scope

This part of CISPR 16 specifies the technical requirements and validation procedures for antenna calibration sites (CALTS) and reference test sites (REFTS) used for antenna calibration and site validation in EMC radiated disturbance and immunity testing. It addresses site design (ground plane size and conductivity, site dimensions), recommended antenna characteristics and positioning, validation methods (site attenuation, validation by comparison, verification of field uniformity), measurement step sizes and uncertainty considerations, and specific procedures for different frequency ranges (notably 5 MHz to 18 GHz and 30 MHz to 1 000 MHz where applicable). The consolidated edition includes amendments that extend and clarify validation methods and measurement requirements.

Key topics and requirements

• Definitions and terms for antennas, measurement sites and calibration concepts (CALTS, REFTS, FAR, SIL, VP, etc.).
• Physical site requirements: minimum ground plane size, site clearances, boundaries and measures to minimise reflections.
• Validation procedures: site attenuation measurement methods, comparison techniques, and site-compliance criteria for various frequency ranges.
• Antenna calibration: recommended antenna types, calibration distances, antenna factor determination and documentation.
• Uncertainty and measurement step-size guidance for swept-frequency measurements and swept-step resolution.
• Extended validation content introduced by the 2016 amendment (clarifications and additions for 5 MHz–18 GHz, FAR and FAR-related methods).

Typical use and users

Used by EMC laboratories, antenna calibration facilities, accreditation bodies, test-site designers and manufacturers requiring validated radiated-emission and immunity test sites. Also referenced by product standards and national/regional regulatory bodies when assessing or accrediting EMC test facilities and when performing antenna calibrations. Test engineers, metrologists and quality managers use it to design, validate and document compliant calibration and reference sites.

FAQ

Q: What is this standard?

A: CISPR 16-1-5 is the CISPR/IEC basic EMC standard that specifies requirements and validation procedures for antenna calibration sites and reference test sites used in radiated emission and immunity measurements. The consolidated 2016 release includes the 2014 base publication plus the 2016 amendment.

Q: What does it cover?

A: It covers site physical characteristics, measurement geometries and distances, antenna considerations and calibration methods, validation procedures (site attenuation, field uniformity), allowable measurement step sizes and guidance on evaluating and reporting uncertainty for site and antenna calibration measurements across the covered frequency ranges.

Q: Who typically uses it?

A: EMC test laboratories, antenna calibration laboratories, accreditation bodies, test equipment manufacturers, product standards writers and regulatory authorities that rely on validated radiated test sites for compliance testing and for establishing traceable antenna calibrations. Test engineers and metrology staff rely on it for procedures and acceptance criteria.

Q: Is it current or superseded?

A: The consolidated edition (CISPR 16-1-5:2014+A1:2016, Edition 2.1) remains the published consolidated version; the IEC webstore lists the consolidated 2016 CSV with a stability/maintenance reference (stability date displayed on the IEC record). Users should check the IEC or their national body for any later amendments, corrigenda or newer editions after 16 December 2016.

Q: Is it part of a series?

A: Yes — it is one part of the CISPR 16 series ("Specification for radio disturbance and immunity measuring apparatus and methods"), which includes multiple parts covering measuring apparatus, ancillary equipment, site validation and uncertainty guidance (e.g., CISPR 16-1-1, 16-1-4, 16-1-6, 16-4-1).

Q: What are the key keywords?

A: Antenna calibration, calibration site (CALTS), reference test site (REFTS), site validation, antenna factor (AF), site attenuation, measurement uncertainty, EMC, radiated emissions, immunity testing.
