The customer did the conducted tests for 30 to 45 MHz and the radiation is very high. It would be better to use LEONI's 647-4 shield. It exceeded the limit by about 6dB, but failed to pass level 3.If LEONI DACAR 546 unshielded twisted pair is used, the radiation exceeds the limit of 20dB.Please provide the following related documentation and optimization configuration.

The application  is DVR and the OEM is oversea truck brand.

Best regards,

Wenting
