About:

The CDN-M2/M3 coupling and decoupling network is designed according to the requirements of the National Standard of the People's Republic of China GB/T17626.6-2008/IEC61000-4-6:2006 for the CDN-M2/M3 coupling and decoupling network (CDN -M2 double line, CDN-M3 three line). This instrument combines CDN-M2 and CDN-M3 into one; according to the different needs of the user, the user can conveniently select through the buttons on the upper panel of the instrument.

Coupling and decoupling devices are used to properly couple disturbance signals to various cables connected to the equipment under test; and to prevent test signals from affecting non-device equipment and systems under test; according to GB/T17626.6-2008/IEC61000-4 -6: 2006; CDN coupling and decoupling networks are used to measure the performance of the conducted disturbance immunity of the equipment under test in the range of 9k ~ 80MHz.

Coupling and decoupling devices (i.e. CDN) can be used for 30M~300MHz radiation disturbance measurement of electrical lighting equipment; according to the national standard of the People's Republic of China GB17743-2007/CISPR15:2005; for specific measurement methods, please refer to the above standards (will be introduced in detail in the application ).
