ISO3082: ISO3082 conduction anti-interference test problem

Hi Jerry,

Thanks for posting on our forums. Happy for our team to look into this for you and follow-up.

Can you help by sharing some additional details please:

1) What data rate are you running this at?

2) Just wish to double confirm that this is a conducted immunity test and not a radiated immunity test? If it is indeed conducted immunity, can you please share where is the injection point and w.r.t which ground domain?  This will help us during the schematic review.

3) Is there flexibility to upgrade to the ISO1410B and/or putting Y-caps in parallel to the device? Some of this depends on #1 and #2 above, so we'd just to check and align on the setup first before we go too deep.

4) Is there a CISPR or IEC standard that you are trying to meet?

Regards, Abhi

1: The baud rate is 9600

2：this is a conducted immunity test 

Jerry,

To reiterate Abhi's question, can you please share where is the injection point and which ground is being used for the test? 

Conducted immunity performance is highly dependent on the system level design rather than just depending on the IC. To maximize Conducted Immunity performance, we suggest using the ISO1410 instead of the ISO3082. Is this possible for you?

Respectfully,

Lucas
