That, by itself, is evidence valid under the current EMC directive as a justification for not testing. I realise that you want to measure various things yourself, anyway, even if the Directive doesn't require it. Since you made an AMN that works, you could also make an ISN, but the examples given in CISPR 16 and 22 may not have suitable component values for RS-485. -- OOO - Own Opinions Only.
