--- Added "Standard Antenna Method" (see 5.2.5);

--- Added "Measurement method of antenna radiation pattern above 1 GHz and its measurement uncertainty assessment" (see Appendix I).

This document is equivalent to CISPR16-1-6.2022 "Radio disturbance and immunity measurement equipment and measurement methods specification 1-6 Part 1: EMC antenna calibration of radio disturbance and immunity measuring equipment.

The following minimal editorial changes were made to this document.

--- As CISPR16-1-6.2022 incorporates the amendment sheet, the formulas, figures and tables are numbered in sequence starting from 5.2.3.

---Corrected the following errors in CISPR16-1-6.2022.

- The uncertainty source in Table 11, "Difference in distance between STA and AUC measurements", corresponds to the standard uncertainty correction.

0.02;

- The contents of paragraphs 2 and 3 in 9.5.1.4 are repeated, and paragraph 2 is deleted;

- Fa(h,p) in B.4.2.2 and B.4.3.2 is corrected to Fa(h,H);

- Z in Figure C.1 is corrected to Z0;

- Figure D.3 shows the measurement data for the case of 1.5m to 2.5m spacing, but the measurement data for 3m is given in the text.

To ensure accuracy, 3m was corrected to 2.5m.

Introduction

To standardize electromagnetic compatibility measurements, consider measurement uncertainties and provide background information related to measurements, as well as to provide electromagnetic compatibility product classification GB/T (Z) 6113 lays the technical foundation for the formulation and revision of the standard. It specifies the radio disturbance and immunity measurement equipment, measurement methods, measurement uncertainty, the first part is the specification of radio disturbance and immunity measurement equipment.

Part 2 is the specification of radio disturbance and immunity measurement methods; Part 3 is the radio disturbance and immunity measurement technical report;

Radio disturbance and immunity measuring equipment and Measurement method specifications Part 1-6.Radio disturbance and immunity Measuring equipment EMC antenna calibration

1 Scope

This document gives the antenna calibration procedure and related information when determining the antenna factor (AF) for antennas used for radiated disturbance measurements.

According to IEC Guide 107, CISPR 16-1-6 is the basic electromagnetic compatibility (EMC) standard used by IEC product committees.

AF is affected by the surrounding environment and its spatial position relative to the source of the emission. This document is concerned with antenna calibration, which aims to provide Free space AF in the boresight direction, applicable to the frequency range of 9kHz~18GHz, including antenna types. monopole antenna, loop antenna, Dipole antennas, biconical antennas, log-periodic dipole array (LPDA) antennas, composite antennas, and horn antennas.

This document also serves as a guide for the evaluation of the measurement uncertainty for each calibration method, calibration arrangement and measuring equipment used for calibration.
