This is what @b4nt doesn't get.
An audio device that passes all tests but does show some signal in the analog path due to injection on some test(s) but does not fail or enter a mode it should not be in can totally pass EMC testing. When a manufacturer states he allows 10mV on the output and all nasties remain below that point then its a pass.
Some weeks ago, you dind't even know or understand a DAC has output stages, lines buffers. You still want to give me scholar or expert lessons?
The standards describe at first precise sets of usual and commonly accepted signals boxes have to be tested agains for CE conpliance (or others). What is the point with that? What, as expert you are, would you additionnaly feed to this boxes to test ther immunity - and to check there is no impact in audio?
As an example: the 90° test Amir finally added, to satisfy @audio2design (but he is still complaining, wouldn't sign the check for that).
