Specification for Radio Disturbance and Immunity Measuring Apparatus and Methods - Part 2-1.Methods of Measurement of Disturbances and Immunity - Conducted Disturbance Measurements1 ScopeGB/T 6113 is designated a basic standard, which specifies the methods of measurement of disturbance phenomena in general in the frequency range 9 kHz to 18 GHz and especially of conducted disturbance phenomena in the frequency range 9 kHz to 30 MHz. With a CDNE, the frequency range is 9 kHz to 300 Hz.2 Normative ReferencesThe following documents are indispensable to the application of this document. In terms of references with a specified date, only versions with a specified date are applicable to this Document. In terms of references without a specified date, the latest version (including all the modifications) is applicable to this Document. GB/T 6113.101-2016 Specification for Radio Disturbance and Immunity Measuring Apparatus and Methods of Measurement - Part 1-1.Radio Disturbance and Immunity Measuring Apparatus - Measuring Equipment (CISPR 16-1-1.2010, IDT)3 Terms, Definitions and Abbreviationsnetwork used to measure (or inject) asymmetric (common mode) voltages on unshielded symmetric signal (e.g. telecommunication) lines while rejecting the symmetric (differential mode) signal4 Types of Disturbance to be MeasuredDepending on the types of disturbance, measurements may be carried out using a measuring receiver with. Measuring receivers incorporating these detectors are specified in GB/T 6113.101-2016.5 Connection of Measuring EquipmentThe artificial network (AN) shall be connected to the reference ground by a low RF impedance, e.g. by direct bonding of the case of the AN to the reference ground of a shielded room, or with a low impedance conductor as short and as wide as practical (the maximum length to width ratio of which is 3.1, and the inductance of which is less than approximately 50 nH corresponding to an impedance of less than approximately 10 Ω at 30 MHz). An in situ test of the voltage division factor as explained in Appendix E is recommended.6 General Measurement Requirements and ConditionsThe measurement signal-to-noise ratio with respect to ambient noise shall meet the following requirements. Should the ambient noise level exceed the required level, it shall be recorded in the test report. The measuring receiver shall be kept tuned to the discrete frequency under investigation and retuned if the frequency fluctuates. Where not specified in the product standard, the EUT shall be configured as described in the following paragraphs.7 Measurement of Disturbances Conducted Along Leads, 9 kHz to 30 MHzThe common mode, differential and unsymmetric mode impedances of actual networks, such as of power mains and telecommunication networks, are location dependent and, in general, time varying.8 Automated Measurement of DisturbancesThe second step in the overall measurement procedure is used to reduce the number of signals collected during prescan and thus aimed at further reduction of the overall measurement time. These processes can accomplish different tasks, e.g. 9 Test Set-up and Measurement Procedure Using the CDNE in the Frequency Range 30 MHz to 300 MHz In general, the level of asymmetric voltage is higher than the level of unintentional symmetric voltage. Therefore, a minimum longitudinal conversion loss (LCL) value of 20 dB is adequate to prevent any influences of the symmetric voltage on the measurement results. The CDNE, with a defined minimum LCL of 20 dB, is not appropriate for EUTs with an intentional differential mode on the mains network. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
