The worse case could be 20LOG(N), where N is the number of power supplies. It
depends on the impedance of the source driving the 50 ohm LISN impedance. If
the source impedance is high (like 500 ohms) the voltages can add linearly.
If the source impedances are low (like 25 ohms) then voltage will

Forgive me for the following (perhaps) silly question, but I'm not an
expert in these topics.
I need to perform conducted emission test (220Vac port) according to
EN55011,
on an industrial power driver (25 kHz Switch Mode Inverter).
Depending upon the application, one to ten drivers

You won't find the 61000-4-X standards on the OJ list because they are
only methods with (typically) a range of test levels and pass criteria,
from which the actual product requirements are then intended to be
specifically chosen and referenced in teh product-specific standards.

Alan et al

There are no standards under the Automotive EMC Directive: it contains its
own requirements. All you should list is the Directive number itself.
