EMI radiation interference(30MHz~300MHz) CDNE test method introduce by newest CISRP-15:2018

EMC test, also known as electromagnetic compatibility, refers to the comprehensive evaluation of electromagnetic interference EMI and anti-interference capability EMS of electronic products. It is one of the most important indicators of product quality. EMC measurement consists of test sites and test instruments The purpose of EMI test is to detect the impact of electromagnetic radiation generated by electrical products on human body, power grid in public places and other electrical products in normal operation.

CISPR (International Special Committee on radio interference) is the abbreviation of the International Special Committee on radio interference, which is mainly responsible for the preparation of standard specifications for EMI radio signal protection test of all types of electrical appliances >9khz The Basic EMC standards of IEC and CISPR are the cornerstone of EMC standards.

The latest version of lamp product standard CISPR15:2018 edition 9.0 has been released on may15,2018. The ninth version replaces the eighth version published in 2013 and its revised version a1:2015. This version is a technical version with major technical changes compared with the previous version.

CISPR -15:2018 all re edited, modified and reorganized, and the restrictions on power supply and battery operating equipment are removed in the scope of application. The frequency of radiation test has been extended, and the limit value of 300MHz to 1GHz radiation disturbance has been increased. The limit value of load end has changed (refer to 6.b in this paper), and the limit value of CDNE has also changed The new standard specifies the new CDNE method, which is only applicable to EUT with clock whose frequency is less than or equal to 30 MHz; For CDNE method, the maximum EUT size is 3m x 1m x 1m (length x width x height), and the test limit (qp/ quasi peak) of CDNE method is more strict.

Therefore, LISUN Launched EMI receiver system for EMI (Electromagnetic Interference) radiation conduction or conducted emissions testing. The EMI-9KB EMI receiver is produced by the full closure structure and strong electro-conductibility material, which has high shielding effect. Due to the new technology for the EMI Test System, it solved the instrument self-EMI problem. The test results are according to the international format test report. The EMI Test System EMI-9KB fully meets CISPR15:2018, CISPR16-1, GB17743, FCC, EN55015 and EN55022.

System Configurations:
• EMI-9KC Test System includes: EMI-9KC EMI Receiver built-in Attenuator (9K-1GHz), LISN-A Artificial Network Power (16A with RS-232 communicate), CDNE-M316 Coupling/Decoupling Network for Emission, 3pcs Isolation Transformers and cables.
• EMI-9KB Test System includes: EMI-9KB EMI Receiver (9K-300MHz), LISN-A Artificial Network Power (5A), CDNE-M316 Coupling/Decoupling Network for Emission, 3pcs Isolation Transformers, Attenuator and cables.
