IEC/EN 61000-4-31, with the title “Testing and measurement techniques–AC mains ports broadband
conducted disturbance immunity test“, specifies the testing in the frequency range 150 kHz to 80 MHz.
Teseq offers with CDND M316-16 a specific coupling/decoupling network for this standard requirement.
The CDND M316-16 provides a longitudinal conversion loss (LCL) of 16 dB in order to inject the common
mode signal as well as the differential mode signal to the EUT port. It can be used for both application
with and without protective earth connection
