GB/T 6113.104-2016 Specification for radio disturbance and immunity measuring apparatus and methods—Part 1-4:Radio disturbance and immunity measuring apparatus—Antennas and test sites for radiated disturbance measurements
Specification for radio disturbance and immunity measuring apparatus and methods—Part 1-4:Radio disturbance and immunity measuring apparatus—Antennas and test sites for radiated disturbance measurements
This part of GB/T 6113 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications for antennas and test sites are included.
Note: in accordance with IEC Guide 107, CISPR 16-1-1 is a basic EMC publication for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC standard. CISPR and its sub-committees (corresponding to Technical Committee SAC/TC 79 and its sub-committees in China) are prepared to co-operate with product committees in the evaluation of the value of particular tests for specific products. The above product committees correspond to the relevant product technical committees in China.
The requirements of this publication apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating range of the measuring equipment.
Methods of radiated disturbance measurement are covered in GB/T 6113.203, and further information on radio disturbance is given in GB/Z 6113.3. Uncertainties, statistics and limit modeling are covered in Part 4 of GB/T 6113.

3 Terms, definitions and abbreviations
For the purposes of this document, the following terms, definitions and abbreviations apply, as well as those of GB/T 6113.101-2016, GB/T 6113.105-2008 and GB/T 4365-2003.
3.1 Terms and definitions
3.1.1
antenna
that part of a transmitting or receiving system that is designed to transmit or to receive electromagnetic waves in a specified way
Note 1: In the context of this standard, the balun is a part of the antenna.
Note 2: This term covers various devices such as the wire antenna, free-space-resonant dipole, hybrid antenna and horn antenna.
3.1.2
balun
passive electrical network for the transformation from a balanced to an unbalanced transmission line or device or vice versa
3.1.3
calibration test site; CALTS
open area test site with metallic ground plane and tightly specified site attenuation performance in horizontal and vertical E-field (electric field) polarization
Note 1: A CALTS is used for determining the free-space antenna factor of an antenna.
Note 2: Site attenuation measurements of a CALTS are used for comparison to corresponding site attenuation measurements of a compliance test site, in order to evaluate the performance of the compliance test site.
3.1.4
common mode absorption device; CMAD
device that may be applied on cables leaving the test volume in radiated emission measurements to reduce the compliance uncertainty
3.1.5
compliance test site; COMTS
environment that assures valid, repeatable measurement results of the disturbance field strength from EUT for comparison to a compliance limit
