The M-series Coupling/Decoupling Networks (CDNs) are designed specifically for conducted disturbance immunity tests performed on power lines according to IEC 61000-4-6.
It should be noted that, in most cases, the total number of power line conductors for the Equipment Under Test (EUT), including line(s), neutral and safety ground, must be equal to the number of lines integral to the CDN.
M-series CDNs provide a means by which common mode RF energy can be coupled onto the EUT power lines while maintaining the required impedance over the ground plane, without interruption of input power. Common mode decoupling is also employed to minimize interference to the power source and/or auxiliary equipment.
The frequency range ofthe testis from 150 kHz up to either 80 or 230 MHz.The test level is typically 1, 3 or 10 Vrms with the test signal 80%, AM modulated with a 1 kHz tone.
