Hi, >My initial question was: >Is there a need to have a license to posses and operate EMC >measurement tools?
It seems evident that (in very short form): - deliberate transmission outside.... not allowed. - for reception.... ok, as long as you don't do anything with any information you might gain from listening to ambients, I don't need a license. Its evident also that for pre-compliance testing any kind of help, locate and test devices (or measurement tools) can be used without the need to go to full compliance testing equipment with anechoic chambers, etc.. Now let me put a more wide open question: When do I need a license for a measurement tools? For instance, is a RF sweep generator a transmitter? Is a wide band RF radiation tracing probe a receiver? This bring me unavoidable to the general questions: What's the definition of a measurement tools in contrast to radio communication equipment who govern, I believe, the requirements for licenses. Where are the transition limits or definitions differences between radio com and measurement tools? What regulation, rule or any other specification defines what is a measurement tool?
