You don't HAVE to do any testing at all. What you have to do is decide what tests YOU need to do to be sure that your product meets the Essential Requirements of the Directive. You may well decide that you do need to apply EN 55022 and EN 55024 in respect of the data port. > > > >My product also has many different field circuits. > >For CISPR 22 does each circuit group need a LISN or just the Ethernet >port and the power supply when testing? Again, you have to decide. It seems to me that you need to connect these ports to auxiliary equipments or to suitable dummy loads. I'm not sure that LISNs are appropriate for such circuits. -- OOO - Own Opinions Only.
