For what it is worth, IF the resistive device is connected to the active device by screened cable and the screening keeps active device emissions within the cable, then the resistive device might act as the antenna and radiate the active devices emissions....
Like a parallel port printer switch did when the box in which the switch was housed was made of plastic - after all the switch was passive!

Is that reasoning sound? It's passive, so it doesn't emit, and I hardly think it could lack immunity, so it's 'EMC benign' and is exempt from the Directive (see 'Whereas (9)' in the new Directive. > >The latest twist in the tail is that the devices are to be marketed to >long term elder care facilities.
