GB/T 6113.106-2018 Specification for radio disturbance and immunity measuring apparatus and methods—Part 1-6:Radio disturbance and immunity measuring apparatus—EMC antenna calibration

Scope

This part of GB/T 6113 provides the antenna calibration procedure and related information for determining the antenna factor (AF) when measuring radiation disturbance. Note: According to IEC Guide 107, CISPR 1616 is the basic electromagnetic compatibility (EMC) standard used by IEC product committees. As stated in IEC Guide 107, it is the responsibility of product committees to determine the applicability of EMC standards. CISPR and its sub-technical committees (corresponding to the SAC/TC 79 Technical Committee and its sub-technical committees in China) cooperate with these product committees in evaluating the value of specific tests for their particular products. The aforementioned product committees correspond to the relevant product technical committees in China. AF is influenced by the surrounding environment and its spatial position relative to the transmitting source. The antenna calibration addressed in this part aims to provide the free-space AF in the direction of the antenna's axis, applicable to the frequency range of 9 kHz to 18 GHz, including antenna types such as monopole antennas, loop antennas, dipole antennas, dual-cone antennas, logarithmic-periodic dipole array (LPDA) antennas, composite antennas, and horn antennas. This part can also serve as a guide for evaluating the measurement uncertainty of each calibration method, calibration setup, and calibration measurement equipment.
